Abstract

This paper endeavours an investigation of voltage and frequency (VF) based BESS (battery energy storage system) controller used in micro grid for analyzing the optimum capability of plant under transient conditions. Micro grid is formed by using three hydro power plants feeding linear and non linear loads. The BESS VF controller used is for load balancing, harmonic suppression, load leveling and neutral current minimization. The proposed BESS controller permits the selection of an optimized battery voltage level and allows independent current control of each phase. The main emphasis is given on maintaining constant voltage and frequency within the micro grid under transient conditions. Micro grid with power plant and BESS controller is modeled in MATLAB/Simulink using Sim Power System Library.
