Micro-grid can be used as a supplement to power supply of large power grids. Combined with smart park, users can easily manage the micro-grid. In the tourist scenic area, the local distributed new energy is mainly used to provide energy for the system. The micro-grid control system as the core of the system controls the optimal operation of the entire smart park. In order to ensure the efficient operation of the entire system, the energy management system is needed for smart control and automatic scheduling. In the grid-connected mode, the main-grid complements the system energy and charges the park energy storage device. In the island mode, the distributed energy is fully used to provide energy for the smart park system. The energy power fluctuates greatly, and the energy management system needs to schedule the micro-grid energy, energy storage system, electric vehicle load and so on, and power quality needs to be monitored. Use of micro-grid control system in the smart parking deploying photovoltaic power generation, wind power generation, charging and exchanging devices and other devices, real-time monitoring of the park of cars, charging cars automatically complete charging, automatic processing of visitor cars into and out of smart park, and improve work efficiency.
