Optimized operation method and device for household hydrogen energy system considering flexible load

The invention provides a household hydrogen energy system optimization operation method and device considering flexible load, and the method comprises the steps: collecting the previous household load information based on a data collection method, and predicting the load demand and energy distribution; constructing a basic structure of the household hydrogen energy system based on distributed energy, and establishing a mathematical model of main components in the system; establishing a multi-objective optimization operation model by taking the minimum life cycle cost and the minimum household energy consumption cost as objectives; and a penalty function-based multi-target particle swarm algorithm is used to solve and obtain an optimal scheme for the operation of the household hydrogen energy system. According to the method, distributed energy, a hydrogen energy storage system and a flexible load are combined, dynamic balance between wind and light output and household energy consumption at different moments i
