Optimal siting and sizing of multiple type DGs for the performance enhancement of Distribution System using Differential Evolution Algorithm

Abstract

The necessity of Distributed Generation (DG) in the modern power system has increased greatly. Optimal placement and sizing of DGs have a significant impact on the objectives of voltage stability enhancement, real and reactive power loss minimization and power system security and reliability. Different types of DGs such as Type I, Type II, Type III and Type IVare placed. The optimal placement of these DGs is found using Voltage Stability Index (VSI). The optimal sizing of these DGs is done using Differential Evolution (DE) algorithm. MATLAB simulation is carried out in standard IEEE 33-bus test system. The test is performed for various combinations of different types of DG. The results show that the voltage stability index along with Differential Evolution algorithm provides better voltage profile and power loss minimization as compared to the system without DG.

IEEE-69 Distribution Network Performance Improvement by Simultaneously Optimal Distributed Generation Sizing and Location Using PSO Algorithm

“…The simulation results show that the modified PSO obtained the minimum power loss and the best voltage profile compared to other heuristic search techniques. While the author in (Karuppiah, 2021), evaluated the active and reactive power loss, voltage stability enhancement in addition to power system reliability and security after integrated DGs into the network. Different types of DGs were placed based on the Voltage Stability Index (VSI) using the Differential Evolution (DE) algorithm.…”
