Abstract

A method for multi-objective reactive power optimization device, computer device and a storage medium, by determining an initial individual optimal particle and an initial global optimal particle foreach of the particles, A normal cloud generator is used to generate adaptive inertial weighting factors to balance the particle swarm exploration and development capability, Selecting Global Optimal Particles, so as to make full use of the directivity guidance information carried by the excellent infeasible solution and feasible solution so as to make the algorithm converge to the Pareto optimal front end quickly, In order to guarantee the distribution uniformity and diversity of Pareto solution set, a set of non-inferior solutions with better Pareto front and uniform distribution are obtainedby using the cyclic abandonment strategy, which provides decision makers with the opportunity to diversify their choices.

Description

technical field [0001] The present application relates to the technical field of power electronics, and in particular to a multi-objective reactive power optimization method, device, computer equipment and storage medium. Background technique [0002] The traditional reactive power optimization problem refers to the power flow optimization problem by changing the generator terminal voltage, on-load transformer ratio and reactive power compensation capacity within a reasonable range of allowable voltage deviation under the condition of system output and network structure. Adjust to minimize the active network loss of the system. [0003] Since the late 1970s, there have been many voltage collapse accidents in the world, and the voltage collapse caused by the lack of sufficient reactive power support during the peak load period. Once it happens, it will be difficult to recover, and it will cause huge economic losses and social life chaos. Therefore, it is necessary to conside...
