LFC System of Multi-Area Interconnected Power Systems using TVAC-PSO based Controller

چکیده
This article presents a Particle Swarm Optimization with timevarying acceleration coefficients (TVAC-PSO) technique for the design of Integral (I) controller for the Load Frequency Control (LFC) system. The LFC modeling is carried out for Multi-area interconnected power systems (MAIPS). The power system comprises non-reheat thermal unit in each control area. The controller gains have been optimized using an efficient TVAC-PSO technique. Two MAIPS models have been considered for the LFC analysis. The dynamic responses have been obtained by giving step load perturbation (SLP) in control area-1. Area frequency and tie line power deviations settle with zero steady state errors. Area frequencies and tie line powers attain their corresponding nominal values. The dynamic responses obtained are as per the LFC requirements.
