Embodiment

[0092] This embodiment describes the method of the present invention based on the actual area electric vehicle data and the actual electric vehicle real-time travel data. The specific data content is:

[0093] A selected urban area has an area of ​​18.7 square kilometers, a population of 56,000, and 500 electric vehicles (set as common models in the market, speed vEV=40km / h, rated power WEV=60kW·h, charging power Pch=7kw). The urban area is divided into 6 districts by the main road, including 2 commercial districts (O1, O2), 2 residential districts (H1, H2), and 2 working districts (W1, W2), such as figure 2 shown. The distribution network is an IEEE33 node system with a rated voltage of 11KV, such as image 3 As shown, GSP node 1 is connected to the upper-level system, nodes 6, 7, 23, 24, and 25 are load nodes in commercial areas, nodes 30, 31, and 32 are load nodes in work areas, and the remaining 23 nodes are residential areas node.

[0094] like figure 1 As shown, the...

Abstract

The invention relates to an electric vehicle charging station planning scheme acquisition method considering different load increases. The electric vehicle charging station planning scheme acquisitionmethod comprises the following steps: 1) acquiring digital features of three travel laws, including an initial state law, a state transition law and a charging information law; 2) simulating the obtained three laws by using a roulette method, and screening charging demand points; 3) establishing a mathematical model based on constraint conditions of traffic constraint, power distribution networkconstraint and economic constraint; 4) solving the mathematical model by adopting a genetic algorithm, setting a fitness function by taking the lowest cost as a principle, setting a death penalty to remove a scheme which does not conform to the distribution network constraint and the cost constraint, and selecting a candidate station set conforming to the traffic constraint; and 5) according to the selected candidate station set conforming to the traffic constraint, planning the charging demands in different load growth modes. Compared with the prior art, the electric vehicle charging stationplanning scheme acquisition method has the advantages of saving resources, ensuring the rationality of the planning scheme, and being high in applicability and the like.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging facility planning, in particular to a method for obtaining a planning scheme of an electric vehicle charging station considering different load increases. Background technique [0002] Against the backdrop of increasing global energy shortage and increasing environmental protection requirements, electric vehicles have gained more and more popular applications due to their remarkable advantages of high efficiency, energy saving, zero emission and pollution-free, and their development is very rapid. Improving charging facilities is one of the important foundations for the promotion of electric vehicles. Reasonable planning of the location and capacity of charging stations can meet the space-time requirements of electric vehicle charging and obtain certain economic benefits. [0003] At present, a large number of experts and scholars have carried out extensive research on electric ...
