Abstract
In order to research the effect of collaborative utilization of energy storage and wind power on wind power grid- connected and carbon emission, this paper discussed the correlation between wind power output and load and effect of wind power connected into power grid on peak load regulation ability of power grid. For the coordination of operation of wind power and energy storage systems, select the collaborative utilization of centralized pumped storage and wind power, investigate the effect of pumped storage participation in peak load regulation and its capacity allocation on grid accommodation of wind power by wind power utilization and quantity proportion, and analyze the cause for low utilization of pumped storage power station as the pumping capacity increases. The research finds that grid accommodation of wind power varies with seasons and under the condition of large wind power installed capacity and exceeding grid accommodation of wind power with conventional power source participating in peak load regulation, the function of pumped storage can show up and collaborative utilization of pumped storage and wind power is an effective means to realize the large-scale wind power grid-connected. Therefore, wind power utilization and quantity proportion and carbon emission reduction benefit, improved by increasing pumped storage per unit capacity, decline as pumping capacity increases, so the pumped storage utilization is lower, and other peak load regulation measures shall be taken, such as time-of-use power price and charging of electric vehicles, to cover the shortage of single peak load regulation.
