Source network load storage interactive scheduling method and system

Abstract

The invention discloses a source network load storage interactive scheduling method and system, and belongs to the technical field of power distribution network scheduling, and the method comprises the steps: obtaining an information interaction condition and the electric energy scheduling capability of a micro-grid, and selecting a micro-grid execution strategy according to the information interaction condition and the electric energy scheduling capability; performing optimization solution on a preset source network load storage scheduling model by using an improved particle swarm optimization algorithm to obtain optimal active power and tie line power of each distributed unit in the microgrid; the improvement is that the d-dimensional component is replaced by the average value of the sum of the d-dimensional components of the individual optimal particles in the iteration process, and the boundary value is replaced by the preset position value when the boundary crossing problem is processed; executing a micro-grid execution strategy by taking the optimal active power and tie line power of each distributed unit in the micro-grid as targets to complete scheduling; the problem that in the prior art, due to the fact that new energy is difficult to digest in order, the light / wind abandoning rate is high is solved, unnecessary thermal power generation and carbon dioxide emission are avoided, reliability is improved, and the system is more environmentally friendly.

Description

technical field [0001] The invention relates to a source-network-load-storage interactive scheduling method and system, belonging to the technical field of distribution network scheduling. Background technique [0002] In recent years, countries around the world have adopted a global agreement to reduce greenhouse gas emissions; with the depletion of fossil energy, the supply of conventional energy is becoming increasingly tight, and the willingness to deal with climate change and environmental protection is becoming stronger and stronger. The development of negative carbon technology and new energy Development and utilization have become a research hotspot; at present, negative carbon technology is still in the research and development and demonstration stage, and the application cost is relatively high. Distributed energy systems based on photovoltaics, wind power and other new energy power generation have developed rapidly ; However, with the rapid increase in the install...
