Abstract

In the context of the “dual carbon” goal, the rapid growth of distributed new energy and electric vehicles (EV) has brought great challenges to the safe and economic operation of the distribution grid. In order to improve the economy and low carbon of distribution network planning, this paper proposes a low carbon planning method of flexible distribution network considering EV orderly charging and discharging. Firstly, a dynamic charging and discharging boundary aggregation model of EV cluster is constructed based on the EV individual power feasible domain model. Secondly, using the carbon emission flow theory as a tool, a two-layer low-carbon planning model of distribution network considering EV orderly charge and discharge is established. The upper layer plans the distribution network lines, two-way charging piles, and intelligent soft open point (SOP), while the lower layer optimizes EV charge and discharge strategy and user consumption strategy with the goal of minimum comprehensive operating cost. Then, the two-layer nonlinear model is transformed into a single-layer mixed-integer second-order cone programming model by means of upper-lower linkage, large M method and second-order cone relaxation, which is solved by commercial solvers. Finally, the feasibility and validity of the model are verified in the improved 33-node system.

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
