| Abstract |
PV Generator at the end of the distribution line affects the direction of the line current and causes voltage increase. Various DER outputs connected to the distribution system have different control characteristics for each connection point. The DER connection point can greatly influence the inverter function and parameter settings. The smart inverter model presented in this paper is a model of simultaneously considering voltage stability of DER linked distribution systems and analyzed at PCC with Matlab-COM. The PCC Voltage when finally stabilized after using Volt-Var function can be adjusted more when there is a margin for the reactive power output. Dynamic Voltage Error Compensation (DVEC) algorithm presented in this paper that automatically refers volt-var curve and measured moving average voltage and finally compensate reactive power output of smart inverter. |
