摘　　要：风能本身的间歇性与无规律性,使得风电大规模并网后对电网造成的负面影响愈来愈显著,而储能装置能有效改善间歇式电源的波动,因此可以利用储能装置和风机构成风储联合发电系统,提高分布式能源的可控性和稳定性。储能系统作为主控单元,储能充电采用V/f控制放电和PQ控制策略,借助PSCAD/EMTDC仿真软件,搭建了风储联合系统各单元模型,实现了风储系统在储能作为电源和负载2种模式下的稳定、可靠运行,仿真结果验证了所建风机、储能模型的可靠性及控制策略的有效性。The intermittent and non-regularity of wind power make the negative effect be more and more obvious when the large scale of the wind power is connected to the grid. The energy storage device can effectively improve the intermittent power fluctuation, therefore wind power and energy storage cogeneration system which is consisted of energy storage and wind turbine has been used to raise the controllability and stability of distributed power supply. The energy storage system was used as the main control unit, the energy storage charge was controlled by V/f while discharge by using PQ control strategy. By means of simulation software PSCAD/ EMTDC, each unit modet of wind power and energy storage cogeneration system were set up. The stable and reliable co-operation was achieved under the condition of wind power and energy storage as source or energy storage. Simulation results verified the accuracy and effectiveness of the models and control strategies in this paper.
