Abstract

Reasonable coordination of reactive power resource of electrical equipment of active distribution grid can improve operation level of voltage

permeability of distribution energy and reduce grid loss. Firstly

the reactive voltage operation mode of active distribution grid is set up

then the dissociation ratio constraints of transformer in the model and the operation ratio constraint discrete reactive power compensation device are transferred to linear constraint by way of introducing binary and continuous variables

and the power balance constraint of the node is relaxed into the second-order cone constraints mode so to obtain the convex programming model of the mixed integral. Finally

the 33-node system is used as simulation test system and the described model is solved by the use of engineering optimization package to obtain the operation scheme of different electrical equipment of active distribution grid. It is shown by the simulation of the test system that the method in this paper can deal with effectively the issue of reactive power voltage operation of non-convex active distribution grid.
