Observer-Based Load Frequency Control for Multi-Area Power System Considering Renewable Energy and Electric Vehicles

This paper studies the stability of multi-area systems with renewable energy and electric vehicles. First of all, the injection of renewable energy reduces the inertia of multi-area systems, by which the change rate of the system frequency deviation is accelerated. We use electric vehicles (EVs) to reduce frequency fluctuations. Since the system state is difficult to be monitored, we plan to use a...
