POWER SYSTEMS STUDIES
Dr. Zhihong Feng leads Powertech’s technical team across a broad spectrum of power system studies—from generation and load interconnection studies, model development or validation for conventional generators and renewable resources, electromagnetic transient analysis to power system planning and operation studies. He is also responsible for business planning and development, technical training, contract negotiation, execution and delivery of projects.
Dr. Saeed Arabi brings more than 40 years of electrical engineering experience to the Power Systems team. Dr. Arabi was born in Tehran, Iran, where he received his B.Sc. degree in Electrical Engineering from Sharif University of Technology in 1974, and worked for both government and private companies before coming to Canada in 1979. He received his M.Sc. and Ph.D. degrees in Electrical Engineering from the University of Manitoba in 1981 and 1985, respectively. He has been with Powertech Labs since 1993.
Dr. Arabi’s interests include power system stability and control, Flexible AC Transmission Systems (FACTS) and High Voltage Direct Current (HVDC) transmission. He has authored numerous publications on these and other subjects.
Dr. Xianrong Wang is a Specialist Expert at Powertech and provides a broad spectrum of power system study and software development services to our electric utilities clients. His main interests include power system optimization, stability and control, modeling, and application of advanced database technologies. He has extensive experience in building power flow and dynamic simulation cases for the entire NERC Eastern-Interconnection (EI) system and many regional systems, as well as performing power system static and dynamic reductions to suit a variety of power system planning and operational study needs. Dr. Wang has expert knowledge of equipment models, simulation techniques, algorithms, and databases.
Dr. Akshaya Kumar Moharana is a senior engineer at Powertech and performs a wide range of power system studies. His consulting activities focus on composite load modeling, small-signal stability analysis, transient stability studies, transfer analysis and evaluation of security limits, Total Transfer Capability (TTC) and System Operating Limit (SOL) calculation, renewable energy integration studies, electromagnetic transient studies, and various NERC/WECC compliance studies.
Dr. Alireza Kahrobaeian is a senior engineer in Powertech’s Power Systems department. Since joining Powertech in 2014, Dr. Kahrobaeian has participated in major power system studies and model validations in North America using the DSATools™ suite of next-generation power system analysis tools for planning and operational studies.
Dr. Farhad Yahyaie is a senior engineer at Powertech and performs a wide range of power system studies including transmission planning and operation studies, dynamic reduction, evaluation of remedial action system and load shedding schemes, control system tuning, harmonics investigation, etc. Dr. Yahyaie is currently leading the consulting activities in model development and validation for renewable energy resources, including wind, solar, and other power electronic-based resources, through field testing and/or system events for compliance with NERC standards in North America or grid interconnection requirements in other countries.
