The integrated operation of wind power and energy storages is the development trend of wind power station. Compared with the energy storage and wind power separately dispatched by the system

the utilization ratio of wind power is improved through the integration of wind farms and energy storages. Based on the operation characteristics of battery energy storage system and the failure mechanism of wind power generators of the integrated station

the loss of load and wind abandoning risk indicators of the integrated operation of wind power and energy storage are built up. A multi-objective optimization dispatch model with the minimum coal consumption of thermal power unit

minimum risk and minimum wind curtailment capacity is proposed. The contradiction in the operation of power system is solved among the risk and coal consumption and wind consumption capacity. The computation example verifies that the model improves the economic efficiency and wind power utilization clearly in the operation of the power system after integration

even though the risk increases a little compared with the traditional unified operation of wind power and energy storage.
