A Control Algorithm for a Standalone Solar Photovoltaic (Pv) -Diesel -Battery Hybrid System

Abstract

This paper presents a Standalone Solar Photovoltaic (PV)-diesel-battery hybrid system with new control algorithm. For obtaining maximum power under varying operating conditions maximum power point tracking (MPPT) algorithm is used. The battery vitality stockpiling system (BESS) is incorporated with diesel motor generator set for the organized load administration and power stream inside the system The proposed system deals with the intermittent nature of the energy generated by the PV array and it also provides power quality improvement. The PV array is integrated through a dc– dc boost converter and is controlled using a maximum power point tracking algorithm to obtain the maximum power under varying operating conditions. A four-leg voltage-source converter with BESS also provides neutral current compensation. The performance of the proposed standalone hybrid system is designed by using the simulation results.
