Voltage Stability Analysis for a Distribution System Integrated with Solar PV and Energy Storage for Demand Response Management
摘要
A PSSE dynamic simulation based study of IEEE-33 bus DN integrated with solar photovoltaic (PV) and ESS to analyze voltage stability, as the ancillary service (AS), and ESS are utilized to ensure grid stability for the demand response management (DRM). The ancillary services strategized to automatically support voltage drop with the DN. To validate the weakest bus VSI was used, to reconfirm the placement of PV. The fluctuation of the PV output is determined by solar irradiation. To demonstrate the fluctuation, two different scenarios were simulated namely the sunny day and cloudy day. In each scenario, the generated voltage was observed. The simulation results were used to indicate the performance of ESS as an ancillary service to ensure grid stability for DRM.
