摘要
复合储能是保障微电网安全稳定的关键技术之一,本文根据储能电源的各自运行优势特点,提出了基于上层下垂-下层倒下垂的分层协调控制策略,上层全钒液流电池储能运用自主下垂控制,超级电容运用倒下垂控制策略,以增加系统稳定性、减少系统建设成本、增加实际工程可行性为优化目标,应用PSCAD专业软件对系统进行模拟仿真,仿真验证本文所采用的控制策略可控制微电网稳定运行,对微电网大容量储能系统的配置与设计提供有价值的参考和帮助。
Composite energy storage is the guarantee of micro power grid security and stability of one of the key technologies,according to their respective operation advantages of energy storage power characteristics,based on the drooping of the upper,lower down sagging layered coordination control strategy,the upper all vanadium flow batteries energy storage using autonomous droop control,super capacitor using the drooping down,with the aim to optimize the system stability,which can realize to reduce construction cost and increase the actual project feasibility,applied PSCAD software system for simulation,simulation in this paper,the control strategy is adopted to control the stability of power grid,is the power of micro grid power generation capacity of energy storage system protection design and configuration provide help and reference value.
