الملخص:In order to overcome the ever-challenging environmental issues caused by greenhouse gas emission, conventional energy sources are gradually being replaced by renewable energy sources. However, the increasing penetration of renewable energy sources leads to the decrease of power system inertia, since renewable sources barely contribute to the inertial response. To tackle this problem, a hybrid energy storage system (HESS), which is composed of the battery and the supercapacitor, is proposed in this project to enhance the system frequency control performance. Besides, a sizing method for the HESS under system contingencies is also presented with the consideration of system cost and operation standards. Furthermore, the battery used for improving secondary frequency control performance in normal operation scenarios with the consideration of SoC regulation is also investigated The effectiveness of the proposed HESS control method is verified through simulations for both contingencies and normal operation scenarios.
