Abstract

In order to understand the interval design of expressway comprehensive energy system, a research on interval design of expressway comprehensive energy system based on multi-objective is put forward. From the perspective of joint planning and operation, taking the planning result as the direction and the operation result as the target calculation basis, this paper establishes the relationship between planning and operation from the perspectives of annualized cost of equipment investment in the planning process, investment time value, energy use cost and operation and maintenance cost in the operation process, and realizes the integrated planning and operation optimization model of comprehensive energy system. Secondly, the optimization process, optimization goal and solving algorithm of the model are put forward. Through examples, it is proved that the load interval of electric vehicle is basically consistent with the trend of electric load. If it is not adjusted, it is easy to cause the phenomenon of "peak plus peak" of electric load. Wind power has a large output at night, and it is easy to produce wind curtailment, so we can focus on how to absorb the excess wind power in these periods.Finally, according to the actual construction needs of users, the construction scheme of comprehensive energy system under fixed investment constraints is put forward, which provides theoretical basis for solving the planning problem of comprehensive energy system.
