Abstract

The invention relates to a hybrid energy storage optimization method and system considering an electric vehicle and photovoltaic, and aims at a power system scene containing an impact load, a hybrid energy storage capacity optimization configuration model is established, and a capacity configuration result is obtained. On the basis, electric vehicle and photovoltaic prediction data and an energy storage system model are further considered, and a two-stage optimization model is constructed. The system operation cost is reduced in the day-ahead stage, the system load fluctuation is reduced in the day-intra stage, and the economic and safe operation of the system is further realized.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging and energy storage, in particular to a hybrid energy storage optimization method and system considering electric vehicles and photovoltaics. Background technique [0002] With the gradual depletion of fossil energy and the increasingly prominent environmental problems, photovoltaic power generation has attracted great attention due to its clean and renewable advantages. On the other hand, as an emerging energy-intensive means of transportation, electric vehicles are also gradually entering the lives of the public. Vigorously promoting electric vehicles has become an important way for countries around the world to ensure energy security, save energy and reduce emissions. However, distributed resources represented by photovoltaic power generation and electric vehicles have great volatility and uncertainty, which will inevitably affect the stability and security of the distribution ...
