Abstract

The present invention provides a mixed integer cone programming based intelligent distribution system synthetic voltage reactive power optimization method. The method comprises: inputting a distribution system structure and a parameter of a distribution system; establishing a time sequence optimization model of a distribution system synthetic voltage reactive power control problem considering various types of adjustment means; converting the established model into a mixed integer second-order cone model; solving the obtained mixed integer second-order cone model by using a mathematical solver capable of solving mixed integer second-order cone programming; and outputting a solution result. The method provided by the present invention greatly reduces solving difficulty and facilitates performing solution by using a solving tool, so that a complex mixed integer non-linear programming problem can be solved, cumbersome iteration and a large number of tests are avoided, and the calculation speed is greatly improved.

Description

technical field [0001] The invention relates to a method for optimizing reactive power of distribution network voltage. In particular, it involves a comprehensive voltage and reactive power optimization method for smart distribution networks based on mixed integer cone programming. Background technique [0002] In the smart distribution network, the use of new energy and renewable energy is mainly connected to the distribution network in a distributed manner in a wide and high density. While meeting the energy demand of the grid, its operating characteristics are less affected by the environment. Large and obvious randomness and volatility will bring many problems to the distribution network, among which the problem of voltage over-limit is particularly serious. Moreover, the output and load of distributed power generation often show a negative correlation, resulting in large fluctuations in the voltage of the distribution network within a certain range. [0003] The volta...
