Microgrid economic operation optimization method based on improved genetic algorithm

Abstract

The invention discloses a microgrid economic operation optimization method based on an improved genetic algorithm. The method comprises the following steps: 1) establishing an economic operation optimization model; 2) initializing an algorithm; 3) performing chaos processing and mapping on population individuals to form an initialized population matrix; 4) calculating population fitness, and recording an optimal individual; 5) performming selection, crisscross and mutation operation; 6) judging whether the population meets the maximum deviation similarity criterion or not, and encoding to forma matrix; 7) judging whether the individuals of the matrix are linearly correlated, if so, performing chaotic processing, and returning to the step 5); otherwise, executing the step 8); 8) calculating population fitness, and updating the optimal individual position; 9) judging whether the maximum iteration frequency is reached or not, if yes, outputting an optimal solution, and otherwise, returning to the step 5). The microgrid economic operation optimization method overcomes the defects that an existing microgrid economic operation optimization method is limited in space search capacity andis prone to falling into local optimum when an optimization model is solved, and a new method is provided for microgrid economic operation optimization.

Description

technical field [0001] The invention relates to the technical field of micro-grid economic operation optimization, in particular to a micro-grid economic operation optimization method based on an improved genetic algorithm. Background technique [0002] Energy is the basis for the survival and development of human society.
