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
Dr. Amin Salmani
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.
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
