Description

technical field [0001] The present invention relates to the technical field of active distribution network operation optimization, and more specifically, to a reactive power and voltage operation control method for active distribution network based on extended cone planning. Background technique [0002] During the evolution from the traditional distribution network to the active distribution network, more and more power equipment is connected to the distribution network system, including distribution transformers, static reactive power compensation devices, group switching capacitor banks, etc. Regulating devices also include energy management and control equipment including distributed power sources such as photovoltaics and wind power. With the access of a large number of controllable power equipment, there are more and more controllable methods in the distribution network, which not only strengthens the active management ability of the active distribution network, but al...

Problems solved by technology

At present, most distributed power sources operate under unit power factor and lack the reactive power adjustment capability of distributed power sources. The access of distributed power sources often causes local voltage rises at grid-connected points.
