comparative example 8 and example 9

[0242] Comparing Case 8 and Case 9, we draw the following conclusions: the residential area is close to the distribution network side of the step-down transformer, and the office area is far away from the node at the transformer. Such a choice is more economical.

Abstract

The invention belongs to the field of electric power system operation and dispatch and relates to a power-grid double-layer optimized dispatching method considering large-scale electric automobile access. Charging and discharging strategies of electric automobiles are researched from two aspects of a power transmission network and a power distribution network, the optimal charging time of the electric automobiles is determined through the power transmission network, further the optimal charging positions of the electric automobiles in the power distribution network are guided, and the load of the power distribution network is centralized on a certain node of the power transmission network, as shown in figure 1. In the power-grid double-layer optimized dispatching method, the coordination effect of wind power, basic load, a thermal generator set and charging and discharging of the electric automobiles is further considered comprehensively, and effective suggestions are proposed for the charging and discharging time and positions of the electric automobiles by means of a model.

Description

technical field [0001] The invention belongs to the field of power system operation and dispatching, and relates to a two-layer optimal dispatching method of a power grid considering the access of large-scale electric vehicles. Background technique [0002] At present, the proportion of coal in primary energy consumption is still very high. Although coal reserves are abundant, the excessive emissions of greenhouse gases and pollutants caused by its production and consumption process are increasing the pressure on environmental protection. In addition, the proven reserves of oil and natural gas are seriously insufficient. Therefore, building a stable, economical, clean, and safe energy supply system faces a series of major challenges. [0003] As a new generation of energy-saving and environment-friendly vehicles, Electric Vehicle (EV) uses electricity instead of traditional petroleum to drive vehicles, which can alleviate the energy shortage and is an inevitable trend in th...
