Load Frequency Control of Multi-Region Interconnected Power Systems with Wind Power and Electric Vehicles Based on Sliding Mode Control

In recent years, wind power systems have been used extensively, which not only improve the efficiency of current conventional generation systems, but also can save traditional fossil fuel resources. However, considering instability power, after being grid connected, it easily cause an impact on stability operation. Considering above problems, this paper considers to make full use energy storage part electric vehicles (EVs) increase Based mathematical model, studies load frequency control (LFC) problem a multi-region interconnected system with and EVs. First, since states are difficult be monitored, state observer is designed estimate state. this, integral sliding mode controller (SMC) realize LFC system. Meanwhile, obtain better performance, further analyzes optimizes parameters based Lyapunov theory. At last, simulations carried out for two regions in Simulink. The results show that controllers effective compensate demand disturbances. addition, demonstrated battery EVs play role peak-shaving valley-filling LFC.
