光伏-储能联合微网系统工程方案设计

Conceptual design for the project of microgrid system interconnected with photovoltaic generation & energy storage

提出分布式发电光伏-储能联合微网系统总体设计方案,进行了并网光伏发电系统、储能系统和微网控制管理系统设计。重点介绍了光伏电池阵列、并网逆变器、储能装置充放电系统、储能系统容量规划、微网电网结构、光储联合微网系统整合运行等设计内容。本工程将建设一个分布式光伏电源、储能系统友好接入电网,实现微电网双向潮流环境下控制保护协调工作的系统。

This paper proposes a design scheme of the distributed photovoltaic generation, energy storage and microgrid sytem, and designs grid connected PV system, energy storage system and microgrid control system. It highlights the design of photovoltaic module matrix, grid-conneded inverter, energy storage charging and discharging system, capacity of the energy storage, architecture of the microgrid, the integrated microgrid system operation and control, etc. The demonstration project will realize PV and energy storage system synchronization in power grid as well as the coordination of control and protection of the two-way power flow microgrid.
