Control Techniques and Simulation for the MPPT Control of a Standalone Solar Photo-Voltaic Hybrid System

Abstract

In this system we used A Control Algorithm. It deals with the nature of energy generated by PV array and provides power quality improvement. A wind-solar hybrid power generator system consisting of photovoltaic modules controlled by MPPT method and connected to a DC-DC boost converter, a grid-connected wind turbine coupled with a permanent magnet synchronous generator (PMSG). Battery energy storage system is integrated to DG set for coordinate load management and power flow in the system. There are some algorithms which we used like harmonic elimination, load balancing, reactive power compensation this algorithm are used under three phase linear and nonlinear loads. A four leg VSC provides neutral current compensation with battery energy storage system. This system is analyzed under different loading conditions using MATLAB/SIMULINK and it is validated to a prototype of the system. The aim of this paper is to review the current state of the design, operation and control requirement of the standalone PV solar-wind hybrid energy systems with conventional backup source i.e. diesel or grid. It also highlights the future development and to increase the attractiveness of the system.
