Voltage and Real Power Loss Analysis Incorporating CE-SSSC with VS-SVC Combination through Fruit Fly Optimization
Authors: , ,
Abstract: This paper focuses an application of Fruit fly Optimization Algorithm based voltage stability enhancement and minimization of real power loss incorporating the combination of Series – Shunt flexible AC transmission system (FACTS) controllers named as Static Synchronous Series Compensator (SSSC) combined with Static Var Compensator (SVC). A new circuit element model of SSSC (CE-SSSC) with variable susceptance model of SVC (VS-SVC) is utilized to control the line power flows and bus voltage magnitudes respectively for real power loss minimization and voltage stability limit improvement. The line quality proximity index (LQP) is used to assess the voltage stability of a power system. The values of Voltage profile improvement, real power loss minimization and the location and size of FACTS devices were optimized Fruit fly Optimization Algorithm (FOA). The results are obtained from three power system test cases (IEEE 14 bus, IEEE 30 bus, IEEE 57 bus) and one practical case such as Indian Utility Neyveli Thermal Power Station (IUNTPS) 23 bus system and compare with other leading evolutionary techniques such as Shuffled Frog Leaping Algorithm (SFLA), Differential Evolution (DE), Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) under three different cases such as normal loading, critical loading and single line outage conditions.
