Achieving thermal power system stability using load frequency controller

Abstract

This paper focuses on load frequency control (LFC) of a single area thermal power system. The purpose of LFC is to minimize the transient varieties due to frequency deviation by ensuring zero steady state error. The frequency deviation normally caused by load perturbation. Hence, the primary goal of this paper is to design LFC for power system stability. Single area thermal power system comprises of governor framework, non-reheat turbine model and generator with load. The closed loop system performances in term of transient and steady state are observed and analyzed by injecting multifarious load perturbation. The simulation results are obtained via simulation works using MATLAB with SIMULINK toolbox.
