Abstract

The invention relates to an optimal configuration method and system for a regional smart energy system. The method comprises the following steps: acquiring load requirements of cold energy, heat energy and electricity energy in regions at all moments in an optimization period; substituting the load requirements of the cold energy, the hot energy and the electric energy in each moment region in the optimization period into a pre-constructed optimization configuration model, and solving the optimization configuration model by using an improved particle swarm algorithm to obtain an optimal solution of the to-be-optimized parameters. According to the technical scheme provided by the invention, the regional smart energy system is planned more reasonably, the operation economy of the system is ensured, and unnecessary loss and pollution are avoided.

Description

technical field [0001] The present invention relates to the technical field of energy Internet planning, and in particular to a method and system for optimal configuration of a regional smart energy system. Background technique [0002] With the rapid development of the energy Internet concept, people pay more and more attention to the comprehensive and efficient utilization of energy, and the problem of urban pollution is also becoming more and more prominent. It is urgent to build a power system that can reduce energy consumption and make full use of green energy. [0003] Therefore, the technicians have given a method such as figure 1 As shown in the urban smart energy system, the urban smart energy system generally includes multiple regional energy subsystems, which are uniformly dispatched by the urban smart energy system management system. Multiple regional energy subsystems also contain a variety of energy equipment. Compared with traditional For the planning of a si...
