[0004] Although there are relatively complete research on the charging mode of electric vehicles and the construction of charging stations in China, and some scholars have also studied the demand for charging power from the perspective of statistical modeling, there is still a lack of research on the entire distribution network level in China, especially It is a distribution network-load coordinated control that integrates a variety of distributed power sources, and realizes the role of charging loads as controllable loads in distribution network control.

The embodiment of the invention discloses a network load coordinated control method and system for electric automobile charging piles. According to the technical scheme illustrated in the embodiment of the invention, the target load of the consumption load of a charging station in the area is obtained by taking the basic balance between distributed generation and load as an optimization target; acertain bandwidth is spaced above and below the target load so as to serve as a fluctuation area of the load, and the charging station sends a charging pile load value to a network load coordinated controller in real time; the charging electricity price of the charging station is moderately increased if the charging pile load value exceeds the maximum value of the target load, and the charging electricity price of the charging station is moderately reduced if the charging pile load value is lower than the minimum value of the target load. Therefore, the charging position of the electric automobile is adjusted, and the rational utilization of resources is realized. The technical scheme illustrated by the embodiment of the invention takes the electric automobile charging with great randomness as an object, carries out load optimization, peak-shaving and valley-filling on an active distribution network and has great practical application values.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a method and system for coordinated control of electric vehicle charging pile network load. Background technique [0002] Electric vehicles have obvious advantages in terms of environmental protection, cleanliness, and energy saving. Electric vehicles do not emit exhaust gas during driving, so they do not pollute the environment. In this sense, electric vehicles can be called "zero-pollution vehicles." In addition, electric vehicles have high energy efficiency, and at the same time, they can be charged with the remaining power at night, which improves the utilization rate of power generation equipment. According to the development pattern of world energy, the characteristics of the diversity of basic energy sources of electric vehicles, and the importance and research momentum of electric vehicles in various countries in the world, it has become the main direction of the devel...
