RESEARCH AND DESIGN OF POWER ELECTRONIC SYSTEMS APPLICATIONS IN SOLAR ENERGY SYSTEMS CONNECTED TO DISTRIBUTION GRID

Abstract

This paper presents the results of research on the application of grid connected solar power. The main content of the article is to control the inverter three-phase grid connected to meet the requirement of controlling the reactive power to zero at a node of the distribution network while maximizing the active power transmitted to the grid. The control circuits are synthesized on the dq coordinate system and verified on the simulation model by Matlab/ Simulink and Experimental model. Both simulation and experimental prototype on 5kW Grid converter have been built to show the acceptable good results and also the practical ready on implementation. The simulation results show the rationality of the control strategies used.
