Title

POWER MANAGEMENT STRATEGY FOR A GRID CONNECTED WIND/PV/HYDRO/BATTERY/ HYBRID SYSTEM

Abstract

This work deals with the frequency regulation, voltage regulation, power management and load levelling of solar photovoltaic (PV)-battery-hydro-wind based micro grid (MG). In this MG, the battery capacity is reduced as compared to a system, where the battery is directly connected to the DC bus of the voltage source converter (VSC). A bidirectional DC–DC converter connects the battery to the DC bus and it controls the charging and discharging current of the battery. It also regulates the DC bus voltage of VSC, frequency and voltage of MG. The proposed system manages the power flow of different sources like wind and hydro and solar PV array. However, the load levelling is managed through the battery and wind. The battery with VSC absorbs the sudden load changes, resulting in rapid regulation of DC link voltage, frequency and voltage of MG. Therefore, the system voltage and frequency regulation allows the active power balance along with the auxiliary services such as reactive power support, source current harmonics mitigation and voltage harmonics reduction at the point of common interconnection. Advanced power technologies are being introduced to improve the characteristics of the wind turbines, and make them more suitable for integration into the power grid. Mathematical model of DFIG with current control loop using PI controller is designed to maximize the power extracted from the wind. Simulation results In MATLAB/SIMULINK show the effectiveness of the strategy Proposed.
