Distributed power source and electric automobile coordination scheduling method and device

Abstract

The invention relates to a distributed power source and electric automobile coordination scheduling method and device. The method comprises steps that an initial value of a scheduling variable is set;according to the initial value of the scheduling variable, a static voltage of each node before optimization is acquired through load flow calculation; according to the static voltage of each node before optimization, an objective function of a distributed power source and electric automobile coordination scheduling model is solved to acquire the scheduling variable after optimization; accordingto the scheduling variable after optimization, a static voltage of each node after optimization is acquired through load flow calculation; if the static voltage of each node after optimization satisfies convergence conditions, the scheduling variable after optimization is outputted, operation ends, if the static voltage of each node after optimization does not satisfy the convergence conditions, the static voltage of each node after optimization is taken as the static voltage of each node before optimization to re-solve the scheduling variable. The method is advantaged in that rapid coordination scheduling of the active power distribution network containing large-scale distributed power sources and electric automobiles is realized.

Description

technical field [0001] The invention relates to the technical field of power system operation analysis, in particular to a method and device for coordinated dispatching of distributed power sources and electric vehicles. Background technique [0002] The shortage of fossil energy and environmental problems are major challenges facing the world in the 21st century. Renewable energy power generation and electric vehicles have incomparable advantages in alleviating the energy crisis and reducing human dependence on traditional fossil energy, and have attracted widespread attention from all over the world. However, the form of distributed power generation using renewable energy in the distribution network has fundamentally changed the operation form of the traditional distribution network. The access of large-scale distributed power sources on the radial passive lines of the distribution network and the change of the power flow distribution will definitely affect the operation ...
