Study on multi-source coordinated peak shaving strategy in Jiajiu area with high proportion of renewable energy

the spatial distribution and regulation characteristics of renewable energy are analyzed separately, and by analyzing the peaking demand of renewable energy access to Xiajiu area, a multi-source coordinated peak-shaving strategy is proposed. Firstly, the equivalent load curve and hydropower output curve are used to determine the starting point of hydropower peaking. The peaking demand, the optimization model with the largest peaking demand is established, and the system optimization model is calculated by using the branch and bound algorithm to determine the unit combination scheme of the system.
