Design and Analysis of Independent Power Supply System for Three-dimensional Parking Lot.

In this paper, the average daily power consumption is calculated as an example of a three-dimensional parking lot in zhengzhou. For its features, a photo-hydrogen complementary independent power supply system is designed, including PV system, controller, energy storage system and hydrogen energy system, etc. Firstly, according to the weather information of Zhengzhou City, the average daily power generation is predicted by the PVsyst software. Secondly, the capacity of the energy storage battery and the hydrogen energy system are determined through calculation. Lastly, the simulation model of photo-hydrogen complementary independent power supply system is built by Simulink. The result shows that the photo-hydrogen complementary power supply system proposed in this paper can effectively achieve energy complementation, can ensure the reliability of power supply, and can still meet the electricity demand of the three-dimensional parking lot through hydrogen energy system power generation in continuous rainy weather.
