Ideal Location for Dg to Advance Their Voltage Profile Using Statcom and Renewable Vitality Sources

Integration of photovoltaic (PV) inverters within power distribution networks using static synchronous compensators (PV-STATCOM) during night time has currently been explored as a method to enhance network performance. The strategic placement of PV-STATCOM devices in distribution systems aims to simultaneously reduce electrical energy losses and enhance voltage profiles while considering fluctuating 24hour load conditions. The influence of installing different numbers of PV-STATCOM units on distribution networks is examined. Virtual STATCOM is widely recognized for improving the voltage stability of weak buses in an 8-bus system. This study focuses on the modeling and simulation of a closed-loop controlled three-phase voltage source inverter-based Virtual STATCOM within such a system. The performance of Virtual STATCOM is analyzed using closed-loop PID and Model Predictive Control (MPC) strategies, and their respective outcomes are compared. The comparison is based on timedomain response parameters such as peak time, rise time, settling time, and steady-state error, using MATLAB. Additionally, the study evaluates real and reactive power performance, in addition to general harmonic distortion (THD) at every bus within the network.
