Transmission Network Loss Reduction and Voltage Profile Improvement Using Network Restructuring and Optimal DG Placement

This paper introduced a method using hybrid combination of network restructuring and optimal placement optimally sized distributed generators (DG) to reduce loss improve voltage profile in practical transmission for scenario high load demand period ten years. A study is performed four cases which includes the test without considering DG restructuring, units proposed grid parameter oriented harmony search algorithm (GPOHSA) GPOHSA. Network achieved by addition new 400 kV Grid-substation (GSS) 220 GSS along with associated system. GPOHSA obtained modification conventional (HSA) where coordinates are used locating individuals an objective space. Performance Improvement Indicators such as real power reduction indicator (SPLRI), reactive (SQLRI) summation node deviation (SNVDRI) evaluate performance each case study. The investment return assessed pay back investments incurred units. It established that effective meet increased time years reduced losses improved profile. Investment on will be recovered 4 Effectiveness better relative genetic (GA) unit placement. MATLAB software India.
