园区光储充微电网系统关键技术研究

Research on key technologies of PV-Storage-Charging sta-tion micro-grid system in the park

以满足将来电网消纳规模化可再生能源的需求出发,研究适合工商业园区推广应用的光储充微电网系统关键技术。首先论述园区光储充微电网的必要性,然后搭建了园区光储充微电网的系统架构,以及各系统通信方式的说明。研究园区光储充微电网的顺序控制策略,包括并网模式和离网模式以及并离网切换技术。最后在园区光储充微电网的经济性,从直接体现和间接体现进行建模分析和论述。

In order to meet the demand of grid absorbing large-scale renewable energy in the future,the key technologies of PV-Storage-Charging station micro-grid system suitable for industrial and commercial parks are studied.Firstly,it discusses the necessity of the micro-grid of PV-Storage-Charging station in the park,and then builds the system architecture of the mi-cro-grid of PV-Storage-Charging station in the park,and the description of the communication methods of each system.The sequential control strategy of the micro-grid of PV-StorageCharging station in the park is studied,including grid-connected mode and off-grid mode and off-grid switching technology.Finally,the economics of the microgrid in PV-Storage-Charging station in the park is modeled and analyzed from direct and indirect manifestation.
