摘要

针对新能源电力系统各节点频率响应过程空间差异显著问题,为提升系统频率稳定性,提出一种考虑节点频率安全约束的惯量优化配置方法。首先,利用节点等效惯量指标分析各节点的频率抗干扰能力,定量表征系统惯量空间分布特性;进而,建立含同步发电机和新能源电源的系统频率响应模型,计算系统惯性中心（COI）频率指标和节点频率指标;然后,将节点等效惯量引入目标函数,分别建立考虑COI频率安全约束和节点频率安全约束的虚拟惯量优化配置模型,并提出节点等效惯量充裕程度的评价标准;最后,改进IEEE 39节点系统仿真算例分析表明,考虑节点频率安全约束进行虚拟惯量优化配置能改善系统频率响应性能并实现节点层级的系统惯量水平评价。

Abstract

Aiming at the problem of significant spatial differences in the frequency response process of each node in the new energy power system, in order to improve the frequency stability of the system, a virtual inertia optimal configuration method considering node frequency security constraints is proposed. Firstly, the frequency disturbance rejection capability of each node is analyzed by using the node equivalent inertia index, and the spatial distribution characteristics of the system inertia are quantitatively characterized. Furthermore, the system frequency response model with synchronous generators and renewable power resources is established, and the system COI frequency index and node frequency index are calculated. Then, the equivalent inertia of the node is introduced into the objective function, and the virtual inertia optimal configuration model considering the COI frequency security constraint and the node frequency security constraint is established respectively, and the evaluation standard of the equivalent inertia adequacy of the node is proposed. Finally, the improved IEEE 39-bus system simulation example analysis shows that the virtual inertia optimal configuration considering the node frequency security constraint can improve the system frequency response performance and realize the system inertia level evaluation at the node level.
