Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0037] The virtual power generation proposed by the embodiments of the present invention refers to using controllable demand-side resources as system backup power. When the grid load value is high, the power consumption of such resources is appropriately reduced, and corresponding power price compensation is performed to users. Since reducing the load is equivalent to increasing power generation...

Abstract

The invention discloses an initiative power distribution network scheduling optimizing method based on virtual power generation. The initiative power distribution network scheduling optimizing method includes the following steps: 1, building a scheduling optimization objective function; 2, obtaining constraint conditions of the scheduling optimization objective function, wherein the constraint conditions include system load balance constraint, system spinning reserving constraint, conventional-unit and demand-side resource technology contributing constraint, conventional unit climbing constraint, conventional-unit minimum running time and minimum stopping time constraint, demand-side maximum continuous controlled time constraint and electricity use mode satisfaction constraint; 3, according to the scheduling optimization objective function and the constraint conditions, determining the starting-stopping states of all the units one period by one period with the disperse particle swarm optimization based on a heuristic rule; 4, after the starting-stopping states of all the units in all the periods are calculated, on the basis of the known starting-stopping states, economically distributing the units according to the constraint conditions. In this way, initiative power distribution network scheduling optimization is achieved.

Description

technical field [0001] The invention belongs to the technical field of optimal dispatching of an active distribution network, and more particularly relates to an optimal dispatching method of an active distribution network based on virtual power generation. Background technique [0002] The large-scale access of distributed power sources, flexible loads and new energy storage systems, as well as the wide application of modern power electronic devices in the power grid, have brought about a series of changes in the system structure and operation mode of the distribution network. As a distribution network system that comprehensively controls distributed energy (DG, flexible loads and energy storage), the active distribution network manages distributed energy at the level of the entire distribution network, not only focusing on local autonomous control, but also on the entire distribution network. The overall optimization and coordination of the power grid provides a new idea f...
