摘要
构建了基于光伏发电、风力发电以及蓄电池储能的多电源直流微网系统。归纳总结出了系统的九种工作模式,提出了包括最大功率跟踪控制、蓄电池充放电控制和直流微网系统的整体协调控制策略。根据分布式电源、电网、负载和蓄电池的工作情况,进行不同模式之间的转换,并完成相应的控制策略,实现了多电源供电的微网系统运营的可靠性。最后通过仿真证实了控制方案的可行性。
This article presents a muhi-power supply DC Micro-grid system based on photovohaic power generation, wind power and battery energy storage. It sums up 9 modes of operation of the system, and presents an overall coordinated control strategy including maximum power tracking control, charge and discharge control for battery, and DC micro-grid system. Based on operational conditions of the distributed power, power grid, the work load and the battery, this control scheme realizes conversion between different modes and completes corresponding control strategies to realize operational reliability of the multi-powered micro-grid system. Finally, the simulation proves the feasibility of the control scheme.
