Generation Coordination and Planning of New Power System Considering Industry Hydrogen Load

Abstract

Considering the impact of industrial hydrogen load on the consumptive capacity of new energy, it is necessary to research the generation coordination and planning of new power systems considering industry hydrogen load. Firstly, considering the energy consumption in the hydrogen production and storage process, as well as the energy storage for hydrogen addition/use, hydrogen load transfer, and interruptible flexibility, an equivalent electrical load conversion model for multiple forms of hydrogen loads is established. Secondly, considering the impact of industrial hydrogen load on the absorption capacity of new energy, the investment decision-making problem of power supply, hydrogen production, and storage equipment is unified with the operation simulation problem of the system at the planning level, to minimize the annual cost of the system. To reduce the complexity of the model, the proposed model plan to the expansion capacity of various types of power sources from the perspective of power types. Finally, by using actual data from a power grid in a certain province as an example, the results verified the rationality and effectiveness of the model compared with the power grid planning without hydrogen load.
