Application of SSPSO and SPSO to Optimal Power Flow Solutions along with SSC Device

摘要

Objectives: In this study, optimization techniques SSPSO and SPSO are used to minimize the total generation cost and active power loss. Methods/Analysis: The power flow analysis gives the information of magnitude of voltages, phase angles and complex power flow at each bus. Optimal Power Flow (OPF) solutions with Static Series Compensator (SSC) FACTS device in the power system to increase the total power transfer. Fast Relative Electrical Distance (F-RED) method based on Simple-Voltage Stability Index (H-index) is used to find the maximum generation supplied to the load. Findings: Comparison was made on SSPSO and SPSO methods and SPSO with SSC gives better results. The H-index is used to judge the power system is stable or unstable. F-RED gives the information, the amount of generators contribution to satisfy the loads. Novelty/ Improvement: SSPSO gives better solution results than SPSO, the methods are applied on IEEE-30 bus system. H- INDEX and F-RED are calculated for the IEEE-5 bus system.
