Embodiment Construction

[0030] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0031] In recent years, the proportion of distributed generator (DG) in the power grid has gradually increased, and its impact on the distribution network cannot be ignored. The active power output by photovoltaic (photovotaic, PV) is affected by the intensity of external sunlight and has strong fluctuations. When the light intensity is high, the high active power of photovoltaic output may cause...

Abstract

The invention discloses a reactive power optimization method, device and equipment for a power system. The method comprises the following steps: acquiring system parameters of each node in the power system; according to the system parameters of the nodes, a first preset index and a clustering algorithm, performing cluster division on the nodes of the power system to obtain a plurality of clusters and centroids of the clusters; establishing a reactive power optimization model of the power system according to the system parameters of each node and the mass center of each cluster; optimizing the reactive power optimization model according to an improved particle swarm algorithm to obtain a reactive power optimization strategy; wherein the learning factor and the weight coefficient of the improved particle swarm algorithm during each iteration are updated according to the number of iterations; and performing reactive power optimization on the power system according to the reactive power optimization strategy. By continuously updating the learning factor and the weight coefficient, the updating speed of the particles in the particle swarm algorithm can be adjusted according to the number of iterations, the optimization effect of the algorithm is improved, and therefore the reactive power optimization effect of the power system on the power system with the distributed power supply is improved.

Description

technical field [0001] The present application belongs to the technical field of reactive power compensation, and in particular relates to a reactive power optimization method, device and equipment of a power system. Background technique [0002] In recent years, the proportion of distributed generator (DG) in the power grid has gradually increased, and its impact on the distribution network cannot be ignored. [0003] In the traditional distribution network, reactive power optimization is mainly carried out by adjusting the number of capacitor groups or on-load tap changer. However, due to the randomness and volatility of distributed power sources, the traditional reactive power optimization method is not effective The optimization effect of the power system with distributed generation is poor. Contents of the invention [0004] In view of this, the present invention provides a power system reactive power optimization method, device and equipment, aiming at solving the p...
