COORDINATED OPTIMIZATION PEAK SHAVING METHOD FOR PLURALITY OF POWER SUPPLIES BASED ON FLUCTUATION CHARACTERISTICS OF RENEWABLE ENERGY

Disclosed is a coordinated peak shaving optimization method for a plurality of power supplies based on a fluctuation characteristic of a renewable energy source, including the following steps: s: determining a weekly generated electricity quantity of hydropower based on an available capacity and a storage capacity of an electricity quantity; s: predicting a renewable energy power generation curve and a load curve of a system weekly; s: determining a start point of peak shaving of the hydropower based on an external transmission curve, the renewable energy generation curve, and the load curve of the system and a generating capacity of the hydropower; s: determining a weekly peak shaving demand of the system; and s: establishing an optimization model with a maximum peak shaving demand. The present disclosure proposes a reasonable arrangement for peak shaving, so as to resolve an accommodation problem caused by large-scale access of a renewable energy source.
