Embodiment Construction

[0039] Aiming at the expansion planning problem of the power distribution system, the present invention proposes a comprehensive planning strategy of the power distribution system that can take into account the adaptation cost. The present invention firstly introduces the basic model of power distribution system expansion planning, and then gives the calculation methods of electric vehicle charging load in free charging mode and ordered charging mode respectively. On this basis, starting from the three uncertain factors of the development level of conventional load in the future, the number of electric vehicles, and whether the orderly charging strategy can be implemented smoothly, a comprehensive planning strategy for power distribution system that can take into account the cost of adaptation is proposed.

[0040] A 54-node power distribution system containing 50 load nodes is used to illustrate the basic features of the flexible distribution system planning method proposed by...

Abstract

The invention discloses a power distribution system comprehensive planning method suitable for electric car large-scale application. The method includes the following steps that firstly, according to a free charging mode and a sequential charging mode, methods for calculating electric car charging loads are provided respectively, and a feasible real-time dispatching strategy is provided for the sequential charging mode; secondly, starting from the three uncertain factors of the annual common load development level of the planning level, the electric car ownership and the condition whether the sequential charging strategy can be smoothly implemented or not, a set of future possible scenes is established; finally, a power distribution system flexible planning method suitable for cost is developed. According to the power distribution system comprehensive planning method, an initial establishment scheme with the small cost sum can be provided for investors and economic risks are avoided.

Description

technical field [0001] The invention relates to a method for comprehensive planning of a power distribution system suitable for large-scale application of electric vehicles, and belongs to the technical field of power distribution system expansion planning. Background technique [0002] When conducting theoretical research on power distribution system expansion planning, how to take into account the adaptability of the planning scheme to other possible scenarios in the future has not been reported in the literature. After the widespread access of electric vehicles, the expansion planning stage of the power distribution system will face more uncertain factors. It is particularly important to carry out research on the comprehensive planning strategy of the power distribution system that can take into account the adaptability of the planning scheme to other possible scenarios in the future. In this context, the present invention proposes a comprehensive distribution system plan...
