New energy enriched region gas and electricity bi-directional peak regulation system

Abstract

The invention relates to a new energy enriched region gas and electricity bi-directional peak regulation system. The system comprises a new energy power station, a power grid, an electrolytic hydrogenproduction device, a hydrogen cell production device, a natural gas conveying pipeline, a gas power generation device and a ground source heat pump. Superfluous electric energy generated by the new energy power station can be utilized to produce hydrogen, the hydrogen can be utilized to prepare methane which is injected into the natural gas pipeline, the energy storage effect is realized, moreover, the hydrogen can be further utilized to prepare hydrogen cells, and the hydrogen cells are for new energy vehicles. When the power grid electricity peak arrives, the natural gas can be utilized todrive a natural gas generator to carry out power generation for power supply supplement to the power grid, retroegulation is realized through natural gas power generation, a new energy power generation randomness problem is solved, and the gas and electricity bi-directional depth peak regulation effect is realized. The system is advantaged in that a reliable, stable, friendly and adjustable intelligent energy application system is constructed, and the system is suitable for new energy enriched regions.

Description

technical field [0001] The invention relates to an electric power system, in particular to a gas-electricity two-way peak-shaving system in an area rich in new energy. Background technique [0002] As we all know, my country's energy supply and energy demand are in a reverse distribution. In terms of resources, "the west is rich and the east is poor, and the north is more than the south", while the demand is just the opposite. It is worth mentioning that this is not only true of fossil energy such as coal and oil, but also of new energy such as wind energy and solar energy: more than 80% of wind energy resources are distributed in the "Three Norths" region, and solar energy resources are also "the plateau is larger than the plain, and the west is larger than the east." ", while more than 75% of energy demand is concentrated in the eastern and central regions. [0003] On the one hand, the economic development of the "Three North" region is relatively lagging behind, the dem...

Problems solved by technology

[0003] On the one hand, the economic development of the "Three North" region is relatively lagging behind, the demand for electricity is insufficient, and the electricity market is small; on the other hand, both fossil energy and new energy are relatively abundant, which will inevitably lead to contradictions in the consumption of new energy
