Optimal Deployment of Energy Storage for Providing Peak Regulation Service in Smart Grid with Renewable Energy Sources. In: Xue, Y., Zheng, Y., Rahman, S. (eds) Proceedings of PURPLE MOUNTAIN FORUM 2019-International Forum on Smart Grid Protection and Control. PMF PMF 2019 2021. Lecture Notes in Electrical Engineering, vol 584.
Principle of the evaluation method The peak-regulation capability of a power grid refers to the ability of power supply balancing with power load, especially in the peak load and valley load periods. Specifically, the adjustment range of power supply in one day should be high enough to reach the peak load and low enough to reach the valley load.
Also, the peak-regulation capability determines the renewable energy consumption and power loads of cities by mitigating power output fluctuation in the regulation process of power grid.
A visualization method of evaluating peak-regulation capability is proposed. Effective clustering method reduces the number of unit on–off state combinations. Two typical peak-regulation problems in Chinese power grid are analyzed. Four measures are discussed to enhance the peak-regulation capability.
Then, a joint scheduling model is proposed for hybrid energy storage system to perform peak shaving and frequency regulation services to coordinate and optimize the output strategies of battery energy storage and flywheel energy storage, and minimize the total operation cost of microgrid.
