The invention provides an intelligent scheduling method and system for an optical storage and charging micro-grid system, and relates to the technical field of power scheduling, and the method comprises the steps: obtaining the current photovoltaic installed capacity, the current energy storage installed capacity, and the corresponding current collection time, current weather data and current electricity price, and forming a first feature vector; according to the obtained current photovoltaic power generation power sequence of the park, the obtained current charging power sequence of the charging pile system and the obtained current load power sequence of the rest loads of the park, predicted photovoltaic power generation power, predicted charging power and predicted load power corresponding to the future time period are obtained through prediction, and a second feature vector is formed; and inputting the first feature vector and the second feature vector into an intelligent scheduling model which is trained and obtained under a corresponding constraint condition by taking power utilization income maximization of the park as a target, so as to predict and obtain the predicted energy storage electric quantity of the energy storage system. And a plurality of characteristic indexes are comprehensively considered, so that the prediction accuracy is improved, and the stability and economical efficiency of the optical storage and charging micro-grid system are effectively improved.

Description

technical field [0001] The invention relates to the technical field of electric power dispatching, in particular to an intelligent dispatching method and system for an optical storage and charging microgrid system. Background technique [0002] As the global carbon emission reduction process continues to deepen, the integration of "light storage and charging" will be the core energy system or business model to further reduce carbon emissions, and it will also be an important starting point for the realization of "carbon neutrality". Photovoltaic, energy storage and charging facilities form a microgrid that interacts intelligently with the public grid based on demand. The application of the energy storage system can also alleviate the impact on the regional power grid when the charging pile is charged with high current. The "light-storage-charge" integrated charging station can not only supply green power for electric vehicles, but also realize auxiliary service functions su...

[0003] However, since the solar-storage-charging micro-grid system involves the combination of multiple systems such as photovoltaic systems, energy storage systems, and charging pile systems, and photovoltaic power generation is greatly affected by factors such as weather, the randomness and volatility of power generation The complexity, security, stability, and power requirements of the intelligent scheduling of the storage and charging system put forward higher requirements. The unreasonable scheduling of the optical storage and charging micro-grid will affect the safety and stability of the power grid and the economy of the system. Therefore, , there is an urgent need for an intelligent scheduling method that can improve the stability and economy of the optical storage charging microgrid system
