Analysis of Frequency Stability in Low Inertia Power Systems Using EV Charging Battery

Modern energy systems supported by renewable energy often have low inertia, which can lead to frequency fluctuations and instability in the power system. On the other hand, there has been significant progress in electric vehicle (EV) technology development. Therefore, a battery technology for charging electric vehicles is proposed to assist the power system in improving frequency stability. This EV charging battery technology works by controlling the charging rate of EV batteries during load fluctuations and frequency fluctuations in the power system. The purpose of this research is to analyze the use of EV charging batteries in enhancing frequency stability in an interconnected power system of two areas after disturbances such as load changes and the addition of renewable energy-based generators such as solar and wind power plants. This research is conducted using MATLAB Simulink modeling.
