Abstract: Power supply structure has undergone tremendous changes with the increasing proportion of renewable energy in the power system. The high permeability, randomness and uncertainty of the output of renewable energy cause problems increasingly prominent, such as demand of power system peak-shaving resources on both power supply and load side. Firstly, this paper summarizes temporal and spatial distribution characteristics of renewable energy, and explains the peak-shaving problem of power system with high proportion of renewable energy. Then, the equipment, characteristics and development trend of various peak-shaving energy storage types are summarized. The paper also elaborates the peak-shaving modes of the demand side in the power system, including demand response construction, power market and auxiliary peak-shaving service market, and enhancing power transmission capacity. Finally, the future research prospects of peak-shaving of power system with high proportion of renewable energy are discussed and prospected.
