【 摘 要 】

Due to the mismatch of energy production and energy demand, multiple ultra-high voltage transmission fed in the grid and reverse-peak shaving characteristics of new energy, higher requirements have been imposed on peak shaving capability of receiving-end grid with large-scale new energy. This paper investigates the planning and configuration strategy of peak shaving power source based on the characteristics of regional power source structure, the configuration strategy of peak shaving power sources, DC links and interregional peak shaving capability. Simulation results of power balance and peak shaving balance calculation from a receiving-end grid in East China demonstrate the effect of peak shaving power sources planning proposed in this paper.
