Problems solved by technology

[0007] The above algorithm cannot take into account both loss and emission in the execution process. Using local search technology, the optimal solution cannot be obtained, and it is easy to fall into the local optimum. These extremely small areas are not fully explored, resulting in the omission of better solutions. possibility

Abstract

The invention discloses an electric power system economic dispatching method based on a quantum beetle antennae algorithm. The method comprises the following steps: (1) initializing the position and initial value of beetle antennae; (2) introducing a search mechanism of quantum behaviors into the beetle antennae algorithm, and establishing Delta quantum potential wells around the beetle antennae position to form a quantum beetle antennae algorithm; (3) establishing an economic dispatching model of the power system by taking the minimum total power generation power value of the generator set as a target function; and (4) optimizing the system economic dispatching model on the basis of a quantum beetle antennae algorithm under constraint conditions, and calculating the combination of the minimum power generation cost and the minimum pollutant emission of the generator set by using an optimal solution. According to the method, a search mechanism of quantum behaviors is introduced into the beetle antennae algorithm, the quantum Delta potential well is established around the beetle antennae position, the probability and uncertainty of the quantum theory are utilized, the convergence speed is effectively increased, the defect that a traditional search method is prone to falling into local optimum is overcome, and the accuracy of a search result is improved.

Description

technical field [0001] The invention relates to the technology of economic dispatching of electric power system, in particular to a method of economic dispatching of electric power system based on quantum beetle whisker algorithm. Background technique [0002] In recent years, people have paid more and more attention to the environmental pollution caused by power plants, and limiting the discharge of pollutants has become a key issue in economical power dispatching. Most of the existing economic power dispatching is aimed at the cost function of a single generator. However, some generators use different fuels, such as coal, natural gas or oil, which have different heat content, and the generating set is faced with the problem of how to choose the most economical fuel. The ultimate goal of environmental economic dispatch is to meet the system load requirements with the minimum operating cost and emission cost while meeting the system load requirements of all generating units....
