Abstract

The invention provides a two-stage dynamic reactive power optimization method based on IPM-intPSO, and the method comprises: solving a discrete variable through an intPSO algorithm, processing a continuous variable through IPM, and obtaining a solving method of static reactive power optimization through the alternate iteration of the discrete variable and the continuous variable; then, on the basis of the network loss change, sequentially segmenting the time periods with violent network loss change, keeping discrete variables in each segment unchanged, and carrying out static reactive power optimization, so that the minimum network loss is ensured, the minimum equipment action frequency is considered, the optimal segmentation number is obtained in a self-adaptive manner, and the defects ofa traditional manual segmentation method based on a load curve are overcome; and finally, carrying out variable correction re-optimization on a heuristic search result of the target function. Compared with a traditional method, the method has the advantages that the optimization result can be further improved, so that the network loss is effectively reduced on the basis of considering the actiontimes of the equipment.

Description

technical field [0001] The invention relates to the technical field of computer simulation, in particular to a two-stage dynamic reactive power optimization method based on IPM-intPSO. Background technique [0002] Reactive power balance is the basic guarantee for the safe and stable operation of the power grid. The voltage level and power quality of the power grid directly depend on the rationality of reactive power distribution. Therefore, how to adjust the existing reactive power control equipment to achieve the optimal operation of the power grid is a very important issue. [0003] Reactive power optimization refers to improving the power quality of the system and reducing the network loss of the system by using reactive power compensation devices, adjusting transformer taps, and changing generator terminal voltage under given system constraints. However, static reactive power optimization only reflects the reactive power optimization results on a single time section, a...
