Model Predictive Load Frequency Control of Isolated Micro-Grid with Electrical Vehicles

摘要

This paper design the load frequency controller based on model predictive control (MPC) for micro-grid with electrical vehicles. The MPC controller is designed by minimizing the objective function. Meanwhile, the limitations of the output power increment and the output power increment rate of each subsystem are also considered in this paper. The simulation results show that when the system is subjected to a load step fluctuation, the proposed MPC can reasonably allocate the output of each subsystem, and quickly eliminate the frequency fluctuation, while respecting the equivalent EVs and diesel power system constraints.
