BUILDING A CONTROL SYSTEM FOR A SOLAR PANEL GRID-CONNECTED INVERTER USING DPC ALGORITHM

Abstract

This paper presents the development of the Direct Power Control (DPC) control
algorithm for the power electronic converter in a grid-connected solar energy
system. The main objective of the paper is to control the three-phase grid-connected
inverter in order to meet the requirements of reactive power control at a specific
node of the low-voltage distribution grid, ensuring voltage balance while
maximizing the power output from solar panels to the grid. The research results were
validated through simulation using Matlab Simulink software, which yielded
promising outcomes and clearly show their readiness for practical applications.
