针对智能电网大扰动暂态稳定性能受到智能电网结构的影响,导致智能电网的运行不稳定,为此提出基于储能技术的智能电网大扰动暂态稳定性能研究。将储能电池模拟成发电机,计算发电机的有功功率和无功功率,分析储能技术改善智能电网大扰动暂态稳定性能的机理;通过定义角频率差的系数,选取智能电网中储能电池输出的功率控制信号,改善智能电网大扰动暂态稳定性能;建立反映智能电网大扰动暂态的等效模型。仿真结果表明,将储能技术应用到智能电网大扰动暂态稳定性能分析中,可以提高智能电网大扰动暂态稳定性能。
The large disturbance transient stability performance of smart grid is affected by the structure of smart grid,which leads to the instability of smart grid operation.Therefore,a large disturbance transient stability performance study of smart grid based on energy storage technology is proposed.The energy storage battery is simulated as a generator,and the active power and reactive power of the generator are calculated to analyse the mechanism of energy storage technology to improve the large disturbance transient stability performance of smart grid.By defining the coefficient of angular frequency difference,the output power control signal of energy storage battery in smart grid is selected to improve the large disturbance transient stability performance of smart grid.the equivalent model model reflecting the large disturbance transient performance of smart grid is established.The simulation results show that the application of energy storage technology to the large disturbance transient stability performance analysis of smart grid can improve the large disturbance transient stability performance of smart grid.
