摘要
目前的储能建模研究大都关注其电磁仿真模型,难以用于大规模储能接入对系统稳定性的影响研究。该文提出了集中式储能电站的机电暂态建模方法,在电力系统分析综合程序PSASP的用户自定义(UD)模块中搭建了考虑限幅和附加功率控制的储能机电暂态仿真模型。在此基础上,提出了储能电站的自适应附加功率控制方法,并搭建了相应控制模块。不同工况下的仿真结果证明,所提模型能够准确模拟储能对电力系统的暂态支撑,所提自适应附加功率控制方案进一步提升了储能电站对系统的暂态支撑能力。
Most of the current studies on the modeling methods of the energy storage system focus on electromagnetic simulation model,which are difficult to be used to simulate the impact of the accessed large-scale energy storage system on the system stability.In this paper,we propose an electromechanical transient modeling method for mass energy storage system,and build an electromechanical transient simulation model for energy storage system considering amplitude limit part and additional power control in the user-defined(UD)module of the Power System Analysis Software Package(PSASP).Based on the electromechanical transient model,the adaptive additional power control method is proposed and the corresponding control module is built.The simulation results under different operating conditions prove that the proposed model can accurately simulate the transient support of the energy storage system to the power system,and the proposed adaptive additional power control method can further improve the transient support capability of the energy storage system.
