Abstract

The invention provides a distributed energy management method and system for a solar charging station. The method comprises the steps of calculating a maximum total charging power provided by a solarpower station; and calculating the charging power of each charging pile with the optimal charging power by taking the maximum total charging power provided by the solar power station as a limit. The technical solution provided by the invention uses the Starkberg game to solve the power distribution solution of an electric vehicle without any centralized controller to ensure the safety of privacy information of the electric vehicle and ensure the stable charge state of energy storage batteries in the charging station, so that a more stable, reliable and efficient charging service is provided for electric vehicle users, and the algorithm is universal.

Description

technical field [0001] The invention belongs to the field of energy management of solar charging stations, and in particular relates to a distributed energy management method and system of solar charging stations. Background technique [0002] With the energy crisis and environmental pollution problems attracting more and more attention, electric vehicles with energy saving and environmental protection characteristics have become the development direction of the global automobile industry. To promote electric vehicles into people's daily life, we must first solve the charging problem of electric vehicles. If electric vehicles are directly connected to the main power grid for charging, the load on the power system will be greatly increased. In order to avoid the impact on the main power grid, a feasible solution is to build solar charging stations that can operate independently. At the same time, solar energy, as a clean and environmentally friendly renewable energy, can well...
