The integrated energy project of the high-speed railway station mainly includes the distributed photovoltaic power generation system (1.284MW) on the roof of the bus building in front of the station and the waiting hall of the long-distance bus building; Photovoltaic shed of bus parking lot and bus parking lot (0.33MW); Charging station system and energy storage system (100kW/200kWh) The project consists of 1.62MW distributed photovoltaics and smart microgrids. Dc microgrid is composed of photovoltaic power generation 100kWp, energy storage system 200kWh, optical storage direct and flexible control equipment, and energy management system, which can not only directly supply power to electrical equipment, but also realize flexible interconnection with AC distribution network, and realize the monitoring of the entire system through hierarchical coordinated control.

The project energy management system (EMS) collects data of photovoltaic power generation, energy storage and electricity consumption to achieve unified data monitoring; The system operation information, fault information, power generation information, power consumption information, energy storage efficiency, battery performance and other information are comprehensively monitored and analyzed. Combined with load prediction based on historical data, peaking and valley price difference, power grid scheduling plan, emergency power supply scheme, etc., the global coordinated and optimal scheduling of energy use, energy storage and load of microgrid is realized.

The photovoltaic part of the roof of the project adopts on-site consumption, surplus electricity online and other methods, intelligent micro-grid photovoltaic power generation mainly meets the electricity demand of charging piles and LED screens and other loads, while storing additional energy into the battery for power supply. In addition, the remaining battery energy can be connected to the grid through the inverter interface. The battery can also be used to cut the peak and fill the valley, store the electric energy during the valley period, and release it during the peak period to achieve additional economic benefits.
