Abstract

This study develops a comprehensive Small Signal Stability Analysis (SSSA) framework model for solar Photo-voltaics (PV) and Battery Energy Storage System (BESS) integrated islanded microgrids. This model incorporates dispatchable Distributed Generators (DG), and solar PV energy source and BESS. The proposed SSSA analytical model investigates the stability of a microgrid when varying PV output power and BESS output power that are integrated into the microgrid system. The development of this analytical model utilizes the latest microgrid modeling methodologies where dynamics of power converters, dynamics of loads, primary (droop) control method and secondary control method are systematically integrated. In this work, modal analysis presents a full picture of the stability of the microgrid with a diverse range of parameters. The proposed SSSA model developed in this study, with great scalability and applicability, can serve as a useful tool for microgrid establishment and analyses in determining the optimal uptake of solar PV energy, sizing of BESS, and also the control parameters for the purpose of maximizing the stability of a microgrid.
