The Integrated Planning Model of Energy Station-Network-Pipe Gallery Considering the Node Path Association

Comprehensive energy system planning is the primary core issue of energy Internet construction. The existing energy station location, capacity determination and pipeline network layout planning of multi energy network are generally obtained by staged optimization or traditional intelligent optimization methods, resulting in the final result of non-optimal solution or local optimal solution; At the same time, the network layout only considers the constraint of pipeline cost, but does not consider the later operation and maintenance cost of the pipeline reduced by the construction of the comprehensive pipeline corridor, which will directly affect the economy of the comprehensive energy system construction scheme. To solve the above two problems, this paper proposes an integrated planning model of energy station-network-pipe corridor considering node path correlation. The model comprehensively considers the investment and operation and maintenance costs of energy station, electricity/gas/heat pipeline laying, and integrated pipe gallery, and adopts the station network coordination optimization method for integrated planning. Take the actual project as an example, compare the proposed model with the existing planning methods, and verify the validity and superiority of the proposed programming model and solution model are proved.)
