Abstract

Aiming at using the energy storage to improve the friendliness of wind power to its grid system, a strategy based on energy storage to stabilize the wind power output fluctuations was given. A regional power grid load and wind power output data of Large-scale wind power grid were counted and analyzed, the Time-domain distribution law of load and wind power output was obtained, the strategy using energy storage to coordinate active power output of the wind farm and load power fluctuations of its power grid system was proposed, And the corresponding mathematical model was established. Made the simulation based on the power system analysis software DIgSILENT-POWERFACTORY13.1, The results show that the modified active power output of wind power through using energy storage can track the load curve variation. the synthesizer output of grid-connected wind power energy storage on the power system can play the role of "load shifting", Energy storage improves the friendliness of wind power to its grid system at a lower cost.
