Abstract

This work deals with neural network control algorithm-based grid connected to solar photo voltaic (PV) system consisting of DC-AC converter. The reference solar-grid current for three-leg VSC are estimated using neural network control algorithm. The neural network control algorithm based solar PV system is modeled in MATLAB R2018a along with SIMULINK.. This study presents an artificial neural network-based controller for regulating the level of active and reactive power output. First, the three phase currents from the VSI are measured and compared with the three reference currents. The neural network is trained to have minimum output error. It was concluded that the power output from the system was found to be190 KVA in case of system having no intelligent controller and 700 KVA in case of system with AAN based control. The voltage of output is maintained to be 20 kV in the grid system for analysis purpose. Thus the proposed control is expected to be implemented in the renewable energy resources for better output.

Highlights

Solar photovoltaic (PV) energy conversion system has shown increase at a moderate annual rate of 60% in the last five years
After making two inverter controls for the system output active power and reactive power are to be studied and further are compared with those modelled with neural network
Artificial neural network technology has the potential to provide an improved method of deriving nonlinear models This study presents an artificial neural network-based controller for regulating the level of active and reactive power output

Summary

Introduction

Solar photovoltaic (PV) energy conversion system has shown increase at a moderate annual rate of 60% in the last five years. This is possible because of alternate clean energy sources, reduction of cost, and efficiency increase of PV modules and subsidy scheme of political regulations. PV installation is classified according to their functional and operating requirements named standalone and grid connected.
