Modeling of an Autonomous Microgrid for Frequency Stability Analysis

Abstract

This paper presents a reduced-order model for an autonomous microgrid (MG) consisting of a micro hydro power plant (MHPP), a wind power plant (WPP), and a battery energy storage system (BESS). The model is developed for frequency stability analysis. The BESS controls the active power flow in the MG by using a properly tuned frequency controller. The model is developed with the purpose of frequency stability analysis of the MG. The results are focused on frequency response for variable load and variable wind speed.
