PHEV Participating in Load Frequency Regulation of Interconnected Smart Grid Using Integral Linear Quadratic Gaussian Control Approach

This paper proposes the high efficient integral linear quadratic gaussian (ILQG) controller design for frequency stabilization of two area tie-in smart grid (SG). In SG, the main challenge is to keep the frequency fluctuation in a acceptable range. The aim of designing the proposed control framework is to stabilize the frequency fluctuation populated with PHEV. The controller is an improved version of linear quadratic gaussian (LQG) with an integral action. The PHEV has been developed as an environmental friendly vehicle. It is normally installed in consumer side. The proposed control method is evaluated by using two area interconnected model. The proposed controller is simulated on MATLAB to measure the effectiveness of the controller. The results ensure that the introduced controller achieves robust performance for frequency stabilization of smart grid.
