Reactive Power Control of Stand-Alone Hybrid Power System Using Genetic Algorithm and Particle Swarm Optimization

摘要

This paper presents automatic reactive power stabilization of a standalone wind-diesel hybrid power system. Reactive power flow equation is used to formulate a mathematical model of system. The voltage is controlled by evaluating small-signal analysis for a static VAR compensator (SVC) and an IEEE Type-1 excitation system. SVC is used to obtain a healthy voltage profile with minimum voltage oscillations to achieve the changing demand of reactive power required by the induction generator and the load. The amplifier gain of the Type-1 SVC is then optimized by employing optimization technique. A comparative study on usage of two optimization algorithms namely genetic algorithm and particle swarm algorithm is shown.
