IEEE PELS & PES Chapter Meeting: Real-time Small Signal Stability Assessment of the Power Electronic-based Components in Distribution Systems

on October 9, 2019 from 6:00 PM to 8:00 PM

Speaker Dr. Amin Salmani
Topic Info

Power Electronic-based Components (PECs) such as Solid State Transformers (SSTs), power electronic-based converters, and motor drives provide highly useful features such as, load regulation, high power factor injection, and improved transient performance for Power Electronic-based Distribution Systems (PEDS). This is especially the case in contemporary power systems and large scale smart grids, which have high penetrations of renewable energy resources. However, the drawback is that they can operate as negative impedances while connected to the Constant Power Loads (CPLs) and CPLs are prone to small-signal instability due to their high power factor and constant-power nature in the system. Therefore, small-signal stability of the PEDS plays a prominent role in the different stages of systems analysis. In this presentation, a new small-signal stability analysis method, based on d-q impedance measurement and Generalized Nyquist Criterion (GNC), is discussed. Furthermore, the stability of an SST connected to an ideal source and programmable AC load is comprehensively investigated under various loading conditions and through Power Hardware-In-the-Loop (PHIL) experimentation.

Speaker Bio

Dr. Amin Salmani has more than 10 years of hands-on experience with solution development, evaluation, design, implementation, and advisory service in energy and power industry with focus on “Power Electronics Applications, Emerging Technologies, Microgrids, and Advanced Energy Storage Systems”.

Dr. Salmani has provided consulting services to two of California’s utilities (PG&E and SDG&E) and has worked for different power systems solution providers (such as Varentec Inc.). In his current role, Amin is a Principal Engineer in DER group at SDG&E.

Amin’s profound insight on energy and power business and technology was acquired through handling projects for SDG&E EPIC Program and grid modernization projects as well as technology development and system integration in Varentec. Amin is licensed Professional Engineer (PE) in the State of California, senior member of IEEE (SMIEEE), and his enhanced analytical thinking and problem-solving ability is backed by a PhD in power systems (FSU, 2014) and proved by 9 registered patents and 20 technical publications.
