Analysis of Integrated Grid-Connected PV/Battery System under Various Operating Conditions

Abstract

In this paper, an effective controller has been designed for grid connected PV/Battery power generating system. The proposed controller is designed to solve the system's power 6 question and power quality problem..In order to stabilize the power fluctuation on the dc-link of the system due to changes in regular environment climates and load variations, the input pulse signal of the inverter is adjusted in such a way that the proposed controller is coupled with the bi-directional controller of the battery, it should provide system stability.Therefore, to test the quality of the proposed controller, two types of environmental changes have been tested in which natural change has been done on the basis of changing light of a whole day, while the second change has been tested in Delhi's 4 years of change of environment.Finally, the MATLAB/Simulink simulation results show that the proposed controller operates well on the grid-connected PV/Battery system.
