Dynamic Self Adjusting FACTS-Switched Filter Compensation Schemes for Wind-Smart Grid Interface Systems
Abstract
This paper validates a number of Flexible AC transmission system (FACTS) filter compensator devices on voltage stabilization and reactive power compensation in a distribution network with embedded wind energy conversion system (WECS). The FACTS filter compensator schemes provide Better voltage stabilization, improved power quality, Interface security, efficient utilization, minimum harmonics levels and energy loss minimization of electricity networks with reactive power and FACTS control, while satisfying the network operating voltage. A novel optimal modified PID controller based on Asymmetrical Switched Pulse Width Modulation (ASPWM) for a set of FACTS devices has been developed for enhancing the dynamic performance of a power system with wind power generation in a wide range of transient conditions including wind gusts. The low cost FACTS filter compensator devices are tested for standalone system (No AC Grid interface) and for AC-Grid interface. The paper presents the application of Multi Objective Particle Swarm Optimization (MOPSO) and Multi Objective Genetic Algorithm (MOGA) techniques in online optimal modified PID controller gain adjusting that dynamically minimize the global dynamic error.
