The Faculty of Engineering at The University of Western Ontario (UWO), in its Strategic Research Plan, has committed to develop a world-class power systems engineering research and education program. As a part of this endeavour, the Faculty has recently recruited three internationally known faculty members, one being a Hydro One senior industrial research chair in power systems. This, in addition to the recently announced NSERC-UNENE Senior Industrial Research Chair in the area of power systems, has made UWO one of the leading centres for power systems engineering research in Canada and around the world. This Power Systems Engineering group resides within the Department of Electrical and Computer Engineering at the University of Western Ontario.
Electric industry restructuring, emerging competitive electricity markets and anticipated rapid growth of alternative energy generation have led to the emergence of many new research opportunities. The key challenges lie in the domain of conditioning, control, protection and operation of the interconnections between the alternate energy generators and the existing electric power grids. Similar research challenges also exist in interfacing alternate energy sources, such as, fuel cells for use in vehicular transportation systems. The expertise and strength of the group lies in power electronic (ac-dc) conditioning technologies, control systems and protection techniques, and is thus very well positioned to perform pioneering research in the abovementioned areas. Although, the group has been established very recently, intensive industry collaborations in above areas have already been established, mainly because of the unique capabilities of this group. The following paragraphs provide brief information about the areas of strength, faculty members, laboratory facilities and collaborations.
AREAS OF STRENGTH
The power systems engineering research group at Western aims at providing innovative solutions for interfacing and interconnecting alternative energy sources, such as, fuel cells, to the emerging electric grids and future transportation systems. Emphasis is on the application of power electronics, computers, digital signal processing, and communication technologies. The group specifically focuses on:
- Cost effective design and implementation of power electronic ac-dc converters/conditioners for low/medium power applications incorporating alternate energy sources and for high power applications employing Flexible AC Transmission System (FACTS) technology
- Integrated control and protection of both the interface and the electric grid
- Unified control and protection of power electronic interface for emerging transportation systems
- Real time voltage and power regulation including power factor improvement; power quality enhancement
- Nuclear power plant control and instrumentation
- Computer-based relays and protection systems
- Smart metering technologies in deregulated systems
- Demand side management, modeling, controllability, communication aspects
The group's expertise is unique for providing cutting-edge technology solutions and setting standards and practices for safe and efficient operation of the power systems of the future that will have high penetration of alternate energy sources.
At present, the group has four internationally known researchers and another faculty member will be added to the group very soon. There are more than thirty graduate students working in the group. There exists a critical mass at Western in this area of importance to the province of Ontario. The group members are:
Since the inception of the Power Systems Engineering Group, the members of the group have been successful in securing funding from various sources to establish state-of-the-art research facilities that do not exist at any other University in Ontario. These facilities are indispensable for conducting research in the areas of interconnection and interface of energy sources to the electric power grid. Specifically, these include:
- Real time simulation of power systems with a Real Time Digital Simulator (RTDS) and a Real Time Playback (RTP) Simulator. These simulators are ideal tools for thoroughly designing, studying, and testing control and protection schemes. They perform the entire system simulation in a “computational time period” which is equivalent to the “real time of occurrence” of the physical phenomena. The importance of these Simulators lie in the fact that any control and protection strategies validated on it will be readily accepted by industry for implementation.
- State-of-the-Art power system protection laboratory with a host of modern protective relays for studying the protection aspects of interconnections of energy sources with the electric grid; and transmission and distribution systems.
- Commercial grade software packages for performing comprehensive and specialized studies related to power system stability, electromagnetic transients, fault studies, etc.
- Facilities for designing, implementing and testing power electronic converters/conditioners, power system protection devices and Flexible AC Transmission System (FACTS) controllers.
- An array of computing and networking facilities for studying IT applications in modern power systems having alternate energy sources.
The above facilities are relocated in the new $ 27.4 million Thompson Engineering Building, a novel research and teaching facility designed to effectively support the new strategic direction of the Faculty of Engineering.
