Abstract: The photovoltaic(PV)/battery hybrid energy conversion system is integrated with grid along with (i) multi functional features of micro grid side bidirectional voltage source converter(?G-VSC) ,(ii) tight voltage regulation capability of battery converter,(iii) MPPT tracking performance of high gain integrated cascaded boost converter which is having quadratic gain and less current ripples. In this paper the PV side converter is controlled by MPPT,P&O algorithm. This paper also proposes a modified instantaneous symmetrical component theory along with a PI controller to the ?G-VSC in micro grid applications with following intelligent functionalities (a) to feed the generated active power in proportional to irradiation levels into the grid (b) compensation of the reactive power, (c) load balancing and (d) mitigation of current harmonics generated by non-linear loads, if any, at the point of common coupling (PCC), thus enabling the grid to supply only sinusoidal current at unity power factor. The battery energy storage system (BESS) is regulated to balance the power between PV generation and utility grid. A new control algorithm is also proposed in this paper for the battery converter with tight DC link voltage regulation capability. The dynamic performance of battery converter is investigated and compared with conventional average current mode control (ACMC). A model of a hybrid PV Energy Conversion System is developed and simulated in MATLAB/SIMULINK environment. The effectiveness of the proposed control strategies for HGICB converter and ?G-VSC with battery energy conversion system are validated through extensive simulation studies.
