Hydrogen is obtained in a low peak period, hydrogen is used for power generation in a peak period, the power consumption cost of a factory is saved, the power supply quality is improved, waste heat generated by power generation is utilized, and the comprehensive energy consumption cost of the factory is reduced.

Description

technical field [0001] This application relates to the field of power system planning, in particular to an integrated energy system containing hydrogen energy storage. Background technique [0002] At present, many regions have begun to implement peak-valley electricity price, which is also called "time-of-use electricity price", which is an electricity price system that calculates electricity charges separately according to peak electricity consumption and low-valley electricity consumption. Peak power consumption generally refers to the power consumption when the power consumption units are relatively concentrated and the power supply is tense. For example, during the day, the charging standard is higher. Low-peak electricity consumption generally refers to the electricity consumption when there are fewer power-consuming units and sufficient power supply. For example, at night, the charging standard is lower. [0003] Enterprises with single-shift production originally us...
