DETERMINATION OF OPTIMAL LOCATION OF SVC CONTROLLER DEVICES IN ELECTRIC TRANSMISSION SYSTEM BY USING PSO METHOD
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 2
Abstract
This paper aims to identify the optimal location for the installation of SVC controller using Particle Swarm Optimization (PSO) method to mitigate small signal oscillations in a multi machine power system reducing the power losses. The SVC is required to regulate bus voltages and control shunt capacitor banks located at the transmission system other nearby stations. This way proper capacitor switching strategy is established to reduce daily and seasonal voltage fluctuations to within acceptable limits. However, performance of any FACTS devices mainly depends upon its parameters and suitable location in the transmission system .PSO method is an efficient and general solution to solve most non linear optimization problems with nonlinear inequality constraints. In power transmission oscillations require wide area system supervision and effective control scheme for that area. For this application we are providing time delays in the wide area control loop which plays a significant role in the controller design. Based on this methodology, an innovative approach is presented considering this time delay, we can vary the power angle and making wide area damping control feasible. Only with such a control scheme, UPFC controller or SSSC and STATCOM can be applied beneficially in the future.
