Ideal Renewable Energy Utilization Through Sectionalization of Battery Banks in Microgrid

Abstract

Hybrid energy system consists of two or  more forms of energy sources. This dissertation presents a  control of a micro-grid which is fed by hybrid energy  sources. It is fed by wind energy, the conversion of which is  done via a setup which has a doubly fed induction generator  (DFIG) and a battery bank with a common DC bus. It is  also fed by solar energy, the conversion of which is done  using a solar photovoltaic (PV) array. The common DC bus  is used for evacuating this power via DC-DC boost  converter. A vector control of LSC is used for managing the  voltage and frequency. The setup works when wind power  source is inaccessible. The algorithm for both the energy  blocks contains a maximum power point tracking (MPPT).  The simulation for the said mode has been developed using  MATLAB. A prototype is finally implemented. The study  of the said model is then made for various inputs under  various load conditions. It is seen that the power quality  remains within the satisfactory breaking points at high  terminals.
