Abstract

The present invention provides a method and system for evaluating the life-cycle economics of a solar-storage-charging integrated power station. Under the scenario of using a chemical battery as an energy storage system, the annual maximum cost of a photovoltaic electric vehicle charging station considering the life-cycle cost of an energy storage battery is With revenue as the goal, establish a life-cycle revenue model for photovoltaic-storage-charge integrated power stations, use multi-population genetic algorithm to solve the established revenue model to determine the optimal photovoltaic and energy storage capacity when the revenue is maximized, and then combine to establish technical economic benefits and financial benefits The mathematical model of the indicator and the probability model establish a model to evaluate the life cycle economics of the integrated solar-storage-charger power station to evaluate the economic benefits. The method and system have established a model for evaluating the life-cycle economics of a solar-storage-charge integrated power station, and evaluated the economics under different solar-storage capacity configurations, and have better verified the effectiveness of adding battery energy storage to a photovoltaic vehicle charging station. Necessity and its possibility of optimal gain.

Description

technical field [0001] The present invention relates to, and more specifically relates to, a method and system for evaluating the life-cycle economics of an integrated solar-storage-charging power station. Background technique [0002] In recent years, the establishment of photovoltaic charging stations for electric vehicles has made great contributions to improving the environment and saving energy. However, the intermittent factor of light energy cannot instantly match the charging demand of electric vehicles. Because energy storage can be dispatched, if energy storage is added to photovoltaic vehicle charging stations, this problem can be solved very well. In battery energy storage, lithium-ion batteries and lead-acid batteries have begun commercial operation in my country. In recent years, lithium iron phosphate batteries have been gradually developed and applied in the energy storage industry due to their advantages such as long cycle life, fast charging capability an...
