Root cause analysis and forensic studies of renewable energy resources

To move towards the net-zero carbon emission goal, it is vital to ensure system reliability while increasing the penetration of Inverter Based Renewable (IBR) energy resources on the grid. Although several studies were performed to elaborate on and enhance the performance of these IBR units, network operators still observed the unexpected performance or tripping of these units. This unexpected/unplanned outage of these units especially for the utility-scale (several MW) will result in a less reliable power system. Hence, accurate and detailed forensic studies are necessary to investigate the incident, propose mitigation solutions, and ensure such an incident will not happen. In this presentation, the required steps for performing these studies will be presented. The differences between phasor domain software and Electro Magnetic Transient (EMT) software and the selection of the appropriate software will be discussed.

One major challenge for power system studies for renewable energy resources is the accurate simulation and software modeling of these units. This presentation will also discuss the challenges of detailed modeling of IBR units in well-known simulation platforms. Hence, in this presentation, we provide the recent development of these units where the actual hardware codes can be extracted and used in the power system studies software.

Several root-cause analyses and mitigation solutions will be presented. In addition, some suggestions will be made for generation interconnection studies before energization that can enhance the visibility of IBR behavior and avoid unexpected outages.


Dr. Sam Maleki is Electric Power Engineers (EPE) principal power system specialist with over 12 years of experience in transient and dynamic power system studies. His expertise includes steady-state and dynamic simulation in the phasor domain and Electro Magnetic Transient (EMT) studies. Sam received his Ph.D. degree from the University of Western Ontario, London, Ontario, Canada. He received his master’s degree from the University of UNITEN Malaysia and his bachelor’s degree from Chamran University, Iran. His main interest is power system studies in EMT software with a focus on power system stability and transient studies. He has done several studies globally on HVDC, FACTS, SSR studies, TRV, TOV, Transformers and lines energization, small signal, and transient stability, stabilizers coordination for large power systems, etc. Sam is currently with EPE consulting working on generator interconnection studies and power system failure forensic analysis. He is also leading the automation of complex and time-consuming studies which help the teams to perform a mass number of simulations and optimization without the need for human supervision.
