摘　　要：新型电力系统中储能装机规模的大幅提升,为电化学储能电站参与电网多样化调控功能提供了基础。针对储能电站缺乏一套完善可靠的适用于大电网的仿真模型问题,开展了储能电站机电暂态及中长期动态仿真的建模研究及程序开发,覆盖了正常工况、故障穿越工况、频率支撑以及参与自动发电控制系统(automatic generation control,AGC)二次调频等储能参与大电网调控的典型应用场景。提出了故障穿越期间的功率控制策略模型以及储能参与AGC二次调频模型,并基于实际工程录波曲线及某省级电网案例完成了仿真模型的正确性对比及功能性验证。仿真结果表明,所构建的仿真模型可以适用于大电网多场景的动态仿真,并具有较高的准确性。The increasing capacity of BESS in the new power systems provides a basis for energy storage power stations to participate in the diversified regulation and control functions of the power grid.The electromechanical transient and long-term dynamic simulation modeling and programming of BESS are carried out to upgrade the incomplete model of BESS in large-scaled power systems,covering the typical application scenarios such as the normal operation,fault ride-through,frequency supporting and the participation in the AGC secondary frequency regulation conditions.The article proposes the power control strategy model under the fault ride-through conditions as well as the secondary frequency regulation model in the AGC.The validation and functionality of the simulation model are verified based on the actual recording curves and a provincial power grid case.The simulation results show that the model constructed in this paper can be applied to multi-scenario dynamic simulation of the large power grids with high accuracy.
