Sliding mode controller design for frequency regulation in an interconnected power system

Abstract In this paper, a Sliding mode controller design method for frequency regulation in an interconnected power system is presented. A sliding surface having four parameters has been selected the load control (LFC) model. order to achieve optimal result, parameter of obtained by grey wolf optimization (GWO) and particle swarm (PSO) techniques. The objective function considered as integral square error deviation tie-line exchange. validated through simulation single area well multi-area system. performance also analyzed parametric variation random loading patterns. proposed better than recently reported methods. via GWO 88.91% improvement peak value over Anwar Pan case study 1 similar observed different studies taken from literature.
