Load Frequency Control for EVs based Smart Grid System using PID and MPC

For the Smart Grid (SG) reliability and security, a proficient LFC scheme is highly imperative. However, due to large oscillations, the LFC obligation is not fully viable. Thus, to overcome this inadequacy, an EVs system is employed in the SG that regulates both the frequency and tie-line power variations. The dispersed nature of the EV system facilitates the LFC in compensating the volume insufficiency. In this paper, a comprehensive analysis has been conducted that appraises the impact of load disturbance on the EVs based SG system. Four different control areas are taken for observation and changes in load are anticipated at various sampling times. Matlab-based simulations are carried out that compared the consequences of the load disturbance when the system adapted the PID, Ce-MPC and De-PMC controllers. Simulation outcomes also considered the influences of each control area on its neighbouring area that is coupled through a tie-line. From the results, it is concluded that the De-MPC has edged over other controllers in term of parameter control and improves the stability of the EVs based SG.
