Development of Voltage Control Algorithm for Improving System Stability in Korean Distribution Grids

Problems with overvoltage and reverse energy flow arise as the percentage of distribution resources (DERs) in system rises. This paper implements a MATLAB/Simulink linked model that communicates OpenDSS engine. The point common coupling (PCC) voltage typically mitigates using inverter outputs control. However, case issues occur networks influence volt–var control effect is insufficient to reduce PCC stable range. To improve reactive effect, this proposes active power error compensation methods maximize effect. DER management (DERMS) platform was constructed analyze changing output values. DERMS data are organized based on real line (D/L) where occurred Korea analyzed. method analysis can be used develop an scheme for over described paper.
