Gas-electricity integrated pipe network collaborative planning method and device, electronic equipment and storage medium

Abstract

The invention provides a gas-electricity integrated pipe network collaborative planning method and device, electronic equipment and a storage medium. The method comprises the following steps that: onthe condition that the safe operation constraint of a power network, the safe operation constraint of a biogas network and the constraint of a biomass raw material transportation network are guaranteed, a multi-stage joint planning model with the minimum investment cost and the minimum operation cost as target functions is established, and in addition, the multi-stage joint planning model furthercomprises large-scale biogas engineering construction constraints, total gas production constraints, real-time gas production constraints and equipment investment constraints; and a collaborative planning scheme of the gas-electric integrated pipe network considering the regional biomass supply capacity is determined according to the multi-stage joint planning model. By reasonably selecting the site of the large-scale biogas engineering, the raw material transportation cost is reduced, the planning cost is reduced, the regional supply and demand balance is guaranteed, and the stable operationof the large-scale biogas engineering is promoted.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a collaborative planning method, device, electronic equipment and storage medium of a gas-electricity integrated pipeline network considering regional biomass supply capacity. Background technique [0002] At present, my country has initially built a national natural gas trunk pipeline network, but there are still problems such as lagging construction and development speed, insufficient pipeline facilities, and insufficient interconnection. There are still more than 20% of prefecture-level local areas and about 30% of county-level local areas. Connect the pipeline gas. There is a shortage of civil gas in these areas, the investment in pipeline network laying and transportation costs are too high, and the existing urban gas supply system is difficult to cover new urbanization areas. Develop a large-scale biogas plant (centralized biogasplant, CBP) to produce and supply clean energy....

AI Technical Summary

Problems solved by technology

However, for regional pipeline network planning problems with bio-natural gas projects as gas sources, large-scale bio-natural gas projects usually face problems such as insufficient regional biomass resources and unbalanced supply and demand, which lead to unreasonable natural gas pipeline planning and transmission line expansion planning, making Expansion costs are higher
