Abstract

The invention discloses an electricity-searcher algorithm based on multiple searchers. The heat supply network coordinated operation optimization method comprises the steps that regional electricity-is established; And the heat supply network coordinately operates the mathematical model, and a multi-searcher optimization algorithm is used for managing the thermoelectric energy system in the region, so that the goal of minimum power generation cost of the whole region system is achieved. The multi-searcher optimization algorithm is designed based on the advantages and disadvantages of all heuristic algorithms, and has the advantages of being higher in convergence speed, higher in global convergence and the like compared with a classical moth fire fighting algorithm, a teaching and learningoptimization algorithm and the like.

Description

technical field [0001] The invention relates to the field of regional thermoelectric energy, in particular to a multi-searcher algorithm-based coordinated operation optimization method for electricity-heating networks. Background technique [0002] The power system and the thermal system are naturally complementary, and the unified scheduling of the two can improve the ability to optimize the allocation of resources and the efficiency of energy utilization in a wider range of time and space. In the northern area of ​​my country's central heating, 50%-70% of the existing conventional units are cogeneration units. The power structure dominated by a high proportion of CHP units has brought great challenges to power system dispatching and control. [0003] In order to realize the comprehensive utilization of conventional generating units, heating units and combined heat and power units, the Heat and Power Economic Dispatch (CHPED) is optimized to achieve the optimal power gener...
