Optimal Placement of Static Compensators for Global Voltage Sag Mitigation and Power System Performance Improvement

摘要

This study presents a new multi-objective approach for optimal placement of Static Compensator (STATCOM) for global (overall) voltage sag mitigation as well as for power system performance improvement. The problem is formulated as a non linear constrained multi-objective optimization problem and solved using Genetic Algorithm (GA). The proposed method determines optimal locations of STATCOMs which simultaneously minimizes the overall voltage sags at network buses, bus voltage deviation and system real power loss and maximizes the voltage stability margin of the system. The proposed approach has been applied on IEEE 24-bus Reliability Test System (RTS) and IEEE 57-bus test systems. The details of implementation and simulation results are presented. The application results are promising and encouraging.
