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

Share

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.
