Abstract

The invention discloses an energy hub planning method considering integrated demand response resources. The method comprises the following steps that (1) data acquisition, including weather temperature of different seasons, power load, wind power output, candidate capacity of equipment under planning, investment cost and various parameters for normal operation of the system, is performed; (2) concrete classification and model establishment of the demand response technology are performed according to the controllability of various load; (3) modeling of an energy hub is performed according to the coupling transformation relation of various energy in the energy hub and solution is performed by using cplex; and (4) whether the planning result is more superior after participation of various demand responses is judged and the optimal result is outputted. According to the method, the translatable, transferable and cuttable demand response characteristics of various load are fully utilized toparticipate in planning and operation of the energy hub so that model selection and configuration of various types of equipment can be optimized, the total cost of planning and operation of the energyhub can be reduced and the decision support can be provided for the planning work of the energy hub.

Description

technical field [0001] The invention belongs to the field of energy hub planning, and in particular relates to an energy hub planning method considering comprehensive demand response resources. Background technique [0002] With the deterioration of the environment and the increasing shortage of fossil energy, the development of an integrated energy system that is organically coordinated at all stages of planning, operation, and construction is the only way to achieve sustainable energy development. [0003] As a coupling point, the energy hub realizes the economic dispatch of the hybrid energy system and the global regulation of the optimal power flow. The energy hub is the conversion station of each energy carrier, and the mutual conversion between different energies is realized through corresponding components inside it. Existing planning methods take into account a variety of equipment on the energy supply side, but do not take into account the flexibility and controlla...
