2020 - Rik W. De Doncker

Rik De Doncker

Dedicated to realizing a more efficient and integrated power grid, the groundbreaking power distribution and conversion concepts of Rik De Doncker have been integral to advances in power quality, energy savings, the use of renewable power sources, and development of electric vehicles (EVs). In 1988, during his postdoc at the University of Wisconsin, Madison, he developed a bidirectional DC-to-DC converter for the energy supply systems of the NASA space station. Now known as the dual-active bridge converter, it is one of the most efficient high-power, isolated DC-to-DC converters, and a 7-MW version was recently tested in a 5 kV multiterminal DC grid. His patented work on the auxiliary resonant commutated pole converter (ARCP) resulted in a high-power, yet highly efficient converter capable of pulse-width modulation. Multimegawatt ARCP converters have found use in uninterruptable power supplies, locomotive applications, and ship propulsion systems. His medium-voltage static transfer switch developed in 1993 was commissioned at more than 25 installations in the United States that are still operational today, keeping power up during voltage sags. His patented EV battery interface was licensed by General Electric and is used in the majority of golf carts and hybrid EVs worldwide, providing improved efficiency and a reduction in hybrid vehicle battery size, weight, and cost. His concept of modular multimotor propulsion systems and modular smart batteries further improved the interoperability of EVs with 150-kW DC fast chargers. This multimotor concept has also been implemented in the Audi Q6 eTron propulsion drive. As director of the Institute for Power Electronics and Electrical Drives at RWTH Aachen University, Germany, his current R&D activities focus on power electronic converters for, among others, household appliances, EV propulsion systems, switched reluctance drives, DC battery chargers and high power-density wide bandgap power converters. He is also director of the E.ON Energy Research Center of RWTH, where he conducts research on medium-voltage grid connected inverters and DC transformers. He founded the Center for Flexible Electrical Networks at RWTH to research hybrid interconnected smart distribution grids for massive decentralized and renewable power generation systems.

An IEEE Fellow and the member of the German Academy of Science and Technology (ACATECH), De Doncker is currently Professor at RWTH Aachen University, Aachen, Germany.

2019 - Lionel O. Barthold

Lionel O. Barthold

Lionel O. Barthold’s continued advancements to power transmission technologies have played a prominent role in the reliable and efficient operation of today’s high-voltage transmission systems. His early work on transmission system design parameters ranged from circuit breaker reclosing times to insulation levels of both lines and high-voltage equipment. He was an early proponent of statistical methods in insulation coordination and developer of the digital method for transmission line radio noise prediction. As technical director of General Electric’s “Project EHV,” he redirected work to higher voltages, organized its transfer to the Electric Power Research Institute, and began work on a series of major extra-high-voltage line design reference books. He founded Power Technologies, Inc. (PTI) in 1969, which served as a technical consultant to utility companies around the world during a very rapid expansion of transmission systems at high voltages. Barthold provided the first source of advanced solution methods outside the purview of electrical equipment manufacturers and introduced the first interactive software for load-flow and dynamic analysis of large power systems (PSS/E), which remains the preeminent world resource for that purpose. PTI also established an advanced test center focusing on special challenges in transmission technology ranging from thermomechanical bending protection in underground pipe-type cables to limits to compaction of medium-voltage overhead lines and feasibility demonstrations of high capacity, high-phase-order AC power transmission. Barthold’s recent work has centered on a capacitor-based DC-to-DC transformer, which functions within a DC grid the same way a magnetic transformer does within an AC grid. This transformer has been considered as a key requirement for development of high-voltage DC macrogrids proposed as overlays to AC transmission systems and an important enabler in the shift to renewable energy sources. Other achievements include converting one of four 380-kV AC circuits on a common line from northern to central Germany to high-voltage DC to give central Germany access to a large block of North Sea wind-farm energy.

An IEEE Life Fellow and member of the U.S. National Academy of Engineers, Barthold is an inventor and consultant, Queensbury, NY, USA.

2018 - Hirofumi Akagi

Hirofumi Akagi

One of the most prolific contributors to increasing the use of power electronics to benefit power systems, Hirofumi Akagi’s pioneering work on power conversion techniques has led to energy-saving applications in industrial and residential systems and has been integral to advances in renewable energy systems, electric/hybrid vehicles, and energy storage. Akagi presented the first paper on the theory of instantaneous active and reactive power in three-phase circuits. Known as “p-q theory,” Akagi applied it to a three-phase reactive power compensator consisting of switching devices without any bulky energy storage component. He also experimentally verified innovative operating characteristics that had until then been impossible to obtain through the application of conventional reactive-power theory in single-phase circuits. Considered a fundamental theory for three-phase circuits, Akagi’s p-q theory has allowed students and power engineers to gain insight into the instantaneous concept of voltage, current, active power, and reactive power. It has provided breakthroughs in the control of static synchronous compensators and unified power flow controllers in high-voltage transmission systems,   as well as pure and hybrid active filters. Akagi’s work on developing the three-level neutral-point-clamped (NPC) inverter has impacted high-power converters for medium-voltage motor drives and grid-tied applications. Marking the beginning of multilevel converter technology, the NPC concept has been used around the world in photovoltaic inverters,  general-purpose inverters,   steel mill drives, and bullet trains. Akagi has tackled the detrimental effects of electromagnetic interference (EMI) encountered in power conversion systems with innovative research leading to active and passive filters for reducing conductive EMI and bearing current in motor-drive systems. Akagi is also well known for his innovations regarding pure and hybrid active filters for power conditioning.

An IEEE Fellow and recipient of the 2008 IEEE Richard H. Kaufmann Award, Akagi is a Distinguished Research Professor with the Department of Electrical and Electronic Engineering at the Tokyo Institute of Technology, Tokyo, Japan.

Marian P. Kazmierkowski

With a career dedicated to improving the performance and availability of modern electric drives, Marian P. Kazmierkowski’s pioneering innovations to processing and controlling the flow of electric energy using power electronic converters have impacted applications ranging from industrial machines to transportation systems to renewable energy sources. Kazmierkowski developed the first speed sensorless vector control system for high-power current-source inverter-fed induction motor drives. He also invented current control methods for transistor voltage source inverters with reduced switching frequency that have been used in a commercial series of transistor pulse-width-modulation (PWM) inverter-fed alternating current (ac) servo drive systems manufactured in Poland. His digital-signal-processing-based sensorless control system has improved the performance of induction motors used for drives in trams, trolleys, and subways, permitting a wide range of speed and torque adjustments while enabling full utilization of the direct current voltage supply. The work done by Kazmierkowski and his team has had important implications for renewable energy applications. He has created methods for ac sensorless direct power control of three-phase grid connected PWM converters based on the concept of "virtual flux," which have been used for active and reactive power estimation. He has also developed power electronics grid interfaces for Europe’s Wave Dragon offshore ocean-wave renewable energy converter. Controllers based on his theories can also be found in photovoltaic systems and wind farm converters.

2016 - Arun Phadke

Arun G. Phadke

The pioneering work of Arun Phadke on computer-based protection equipment for providing precise, real-time data on power transmission system conditions has provided the backbone for today’s wide-area measurement and control systems used to ensure power grid reliability and prevent disruptions from leading to large-scale blackouts. Phadke developed synchrophasors for measuring the flow of electricity through the power grid. Synchrophasors are time-synchronized numbers that represent both the magnitude and phase angle of the sine waves found in electricity and are time-synchronized for accuracy. Phadke also developed the phasor measurement unit (PMU) for measuring synchrophasors. PMUs have proven to be the main tool for the monitoring, protection, and control of the grid and are considered a quantum leap over analog technology, quickly providing the information needed to maintain grid stability over a wide region. During the 1990s, Phadke helped develop the concept of adaptive relaying. Using the computing and communications capability of computer relays, this concept allows for automatic adjustment of protective relay characteristics to match prevailing power system conditions to avoid unnecessary trips of equipment as a catastrophic power system event evolves. Phadke’s efforts on advancing computer-based protective relaying began in the early 1970s when his implementation of protective algorithms in an IBM minicomputer and its subsequent installation in a 138-kV substation near Roanoke, Virginia, represented the world’s first communicating relay and fault recorder. Also, his digital symmetrical component distance relay was a significant contribution to the distance protection of transmission lines. His early work on Fourier transforms for voltage and current calculation serves as the foundation for most of the digital relays installed throughout the world today.

An IEEE Life Fellow and member of the U.S. National Academy of Engineering, Phadke is a University Distinguished Research Professor with the Faculty of Engineering at the Virginia Polytechnic Institute and State University, Blacksburg, VA, USA.

Fred Lee

A world authority on high-frequency power conversion design, modeling, and control, Fred C. Lee has pioneered technologies that provide more efficient power conversion and improved reliability in devices and systems, impacting applications ranging from personal computing and mobile devices to military and industrial equipment. Dr. Lee introduced “soft switching” technologies during the 1980s to combat the undesired switching losses, electrical and thermal stresses, and electromagnetic interference caused by high-frequency power conversion. His zero-voltage switching for resonant, quasiresonant, multiresonant, and pulse-width-modulated converters have become core components of modern power electronics equipment and systems. During the 1990s, Dr. Lee and his students developed a novel multiphase voltage regulator (VR) module for new generations of Intel microprocessors. Dr. Lee and his students have generated 25 U.S. patents addressing key areas such as power delivery architecture, modularity and scalability, control and sensing, integrated magnetics, and advanced packaging and integration. Today, every PC and server microprocessor is powered with this VR. These technologies have been further extended to high-performance graphical processors, server chipset and memory devices, networks, telecommunications, and all forms of mobile electronics. Dr. Lee has helped power electronics industries realize their full power-saving potential by overcoming the cost and reliability roadblocks caused by using nonstandard components and labor-intensive manufacturing. He and his team have developed advanced integration concepts and technologies suitable for standardization and automation using integrated power electronics modules (IPEMs) that have provided improvements in performance and cost reduction. IPEMs have been commercialized and are widely used today in powering the new generation of microprocessors, photovoltaic converters, variable-speed motor drives, and electric/hybrid vehicles.

2013 - Hermann W. Dommel

Hermann W. Dommel

Hermann W. Dommel’s development of landmark computer methods for analyzing and modeling the effects of electromagnetic transients and optimizing power flow in power systems has played a critical role in advancing the electric power grid. His pioneering work during the 1960s set the foundation for the electromagnetic transients program (EMTP) software that has become an indispensable tool in the power industry. Electromagnetic transients can occur due to network switching, system faults, or lightning and can cause power surges detrimental to the electric grid. Dr. Dommel’s EMTP technology, which can be found in well-known commercial software packages today, helps utility companies predict these surges for more reliable and efficient operation. Dr. Dommel’s development, further enhancement, and support of the technology have earned him recognition as the “Father of EMTP.” Dr. Dommel also developed methods for optimal power flow with W.F. Tinney in 1968 that were quickly implemented in power system operations centers for real-time monitoring and analysis of the power grid. The paper detailing this work (published in the IEEE Transactions on Power Apparatus and Systems) was voted the fifth-most important paper concerning 20th Century power system analysis. Dr. Dommel’s optimal power flow solutions still play an important role in the efficient operation of large power systems.

An IEEE Fellow, Dr. Dommel’s many honors include the IEEE Power and Energy Society’s Charles Concordia Power Systems Engineering Award (2011). Dr. Dommel is a Professor Emeritus with the University of British Columbia’s Department of Electrical and Computer Engineering, Vancouver, BC, Canada.

The pioneering inventions and leadership of Edmund O. Schweitzer, III, in bringing computer-based protection and control methods to the marketplace have revolutionized safety, reliability, and efficiency in generating, transmitting, and distributing electric power. Dr. Schweitzer envisioned the concept of the “smart grid” long before the term was popularized, recognizing early in his career the importance of computer technology for power protection and control. Microprocessor-based methods, such as digital protective relays, use microcontrollers and software to detect electrical faults in a power system. Digital methods enable engineers to locate power outages more quickly and protect against widespread loss of service compared to traditional electromechanical protective relays. Dr. Schweitzer was not deterred by those in the industry who told him that applying digital technology to power systems was impractical. He founded Schweitzer Engineering Laboratories (SEL) in 1982 to develop and manufacture digital protective relays, driving his research to commercial application. Schweitzer’s innovations have allowed engineers of all backgrounds to monitor, control, and protect power systems in ways not previously imagined. The application of Schweitzer’s digital technology as replacement equipment or in new installations has led to reduced design work in protection and control systems, flexible operation options, and increased reliability, resulting in reduced cost. SEL equipment is in service around the world at voltages from 5 kV through 500 kV, protecting feeders, motors, transformers, capacitor banks, transmission lines, and other power apparatus.

An IEEE Fellow and member of the U.S. National Academy of Engineering, Dr. Schweitzer is currently president and chief executive officer of Schweitzer Engineering Laboratories, Pullman, Wash.

One of the earliest pioneers of digital power flow solutions for the electric power industry, William F. Tinney’s groundbreaking work during the late 1960s while with the Bonneville Power Administration enabled digital computers to solve the power flow problem. The ability to calculate the power flowing on the lines of a large grid given load and generation information is crucial to the planning, design, and reliable operation of the world’s power grids. Even with the advent of digital computers, it wasn’t until Tinney’s breakthrough solutions that computers could provide the analytical tools and services that have enabled the safe expansion of the power grid. Practically every electric power system network computer program developed over the past 40 years is based on his sparse network solution approach. Published in 1967, the sparse matrix technology concept became used worldwide in all power system computer applications requiring solution of power network equations. In 1968, with H.W. Dommel, Tinney introduced the optimal power flow problem and a method for its solution. The paper detailing this revolutionary work that was published in the IEEE Transactions on Power Apparatus and Systems (vol. 87, pp. 1866-1876) was voted the fifth-most important paper in 20th century power system analysis. Soon new power system operations centers were developed that utilized Tinney’s methods for real-time monitoring and analysis of the power grid.

An IEEE Life Fellow, Tinney worked for the Bonneville Power Administration, Portland, Ore., from 1950 to 1979. He is an independent consultant for vendors of power systems software.
