Abstract

The invention provides an improved particle swarm optimization-based economic load dispatching method for a power system, relates to the technical field of power systems, and aims at solving the technical problem of optimization of economic load dispatching of the power system. According to the method, a swarm management rule is introduced into a particle swarm optimization algorithm to form an effective swarm utilization strategy-based particle swarm algorithm; the quantity of particles is effectively changed through a global optimal value change of the swarm; the improved algorithm is high in convergence rate; and the convergence precision is high. The method provided by the invention is applied to economic load dispatching of the power system comprising different units, achieves performance improvement of economic load dispatching of the power system and obtains a good optimization effect.

Description

technical field [0001] The invention relates to power system technology, in particular to a technology based on an improved particle swarm algorithm-based power system economic load distribution method. Background technique [0002] The economic load dispatch (ELD) of power system is one of the typical optimization problems in power system load planning and operation dispatching. Solving this kind of optimization problem can effectively improve the economy and reliability of power system operation. [0003] Through relevant and targeted research on the power system, it is found that: due to the influence of the valve point effect of the generating set, the output characteristic curve of the generating set often presents the characteristics of nonlinear, non-convex, and non-conductive; due to the limitation of the transmission capacity of the distribution network and the stability of the system Therefore, the corresponding problem function is non-differentiable and non-differ...
