Optimization algorithm for target function of comprehensive cost of direct-current power distribution network

Abstract

The invention discloses an optimization algorithm for a target function of the comprehensive cost of a direct-current power distribution network. The optimization algorithm comprises the following steps: initializing algorithm parameters, and determining a set M and a set Z; selecting a position with the largest distance to the first initial position, adding the largest position into the set Z, and deleting the largest position from the set M; respectively calculating the distance from the position Mi in the updated M to each element in the Z, calculating the product of the maximum value and the minimum value of the distance, and storing the position corresponding to the maximum product into a set Z; judging whether the number of the selected initial positions, namely the number of the positions in the set Z, is smaller than ZN or not; if not, the optimal solution obtained through iteration is output; if yes, repeating the steps to select the position with the largest distance to the first initial position, and adding the position into the set Z; according to the optimization algorithm for the objective function of the comprehensive cost of the direct-current power distribution network, the optimization algorithm adopts an artificial bee colony algorithm, and the artificial bee colony algorithm improved by the maximum and minimum products is used for optimization.
