摘要:

为明确混合型储能快速频率支撑对新型电力系统动态特性的影响,寻找不同场景下混合型储能系统的最佳频率控制策略,提出一种具有通用性的混合型储能系统动态建模方法,并基于该模型设计了适用于蓄电池与飞轮储能组成的混合型储能系统的PI、H及滑模控制策略。通过算例分析比较了不同控制策略下该混合储能系统对电网的频率支持能力。结果显示,当蓄电池采用H控制,飞轮储能系统采用滑模控制时可实现最佳频率支撑效果。

关键词: 储能系统, 混合型储能系统, 鲁棒控制, 最优控制

Abstract:

In order to study the influence of hybrid energy storage system with fast frequency response on the dynamics of the new power system, and find the best control strategies for different scenarios, a generalized dynamic model of the hybrid energy storage system is proposed. On the basis of this model, the PI, H∞ and sliding mode controllers for the hybrid energy storage system consisting of battery and flywheel energy storage are designed. A case study serves to compare the different control strategies of the hybrid energy system. The results show that the combination of battery with H∞ control and flywheel with sliding mode control has the best frequency support capability.

Key words: energy storage system, hybrid energy storage system, robust control, optimal control
