Driven by the dual carbon target, renewable energy will be connected to the grid in a large-scale distributed way, and will be mainly concentrated in wind, photovoltaic and land resource-rich distribution network end areas. However, the weak distribution network architecture in these regions and the limited carrying and governance capacity of renewable energy make it difficult to effectively absorb the renewable energy output in peak periods, resulting in large-scale wind and light abandonment.
In response to this problem, this paper adopts a governance idea of using hydrogen energy storage to participate in the renewable energy consumption of the distribution network and meet the demand of users. The use of hydrogen energy storage can not only directly improve the absorption capacity of the distribution network, but also exchange energy with the outside world through the hydrogen network, reduce the dependence of electricity demand side on the distribution network, achieve the “soft off-grid” state, so as to reduce the burden of renewable energy governance of the distribution network, and improve the low-carbon operation economy of the end area of the distribution network.
