| Abstract: | Due to the rapid development of electric vehicles (EVs), the number of EVs has surged. Connecting EVs to micro-grid in charge-discharge scheduling become an effective way to reduce the negative impact of large-scale EVs on the power grid. Thus, given the source-charge characteristics of the EVs, with the access of EVs to DC side in micro AC/DC hybrid power grid, the two-phase robust scheduling model is built to settle the uncertainty in micro-source output and load of the microgrid system and find most economical solution in extreme situations. The model uses a box uncertainty set to describe the uncertainty, and flexibly adjusts the conservatism of the model through uncertain budget. Based on the operation constraints of each unit in the system, the objective function of minimum cost is established, and the model is transformed into a mixed integer linear programming model by the strong duality theory and BIG-M method. Finally, the model is iterated to obtain the optimal solution through the column and constraint generation algorithm. The simulation results of an example simulation show that reasonably utilizing the source-load characteristics of EVs can effectively reduce the microgrid daily operation cost. In the case of 50 EVs in parallel operation, the operation cost in the randomly charging mode is higher than that in the orderly charging and discharging mode by 1069.7 Yuan. In addition, under the restriction of power commutation, with the increase in the number of EV access, the operation cost also shows a trend of declining and then rising. In terms of real-time adjustment costs, the robust scheduling model has favorable economic benefits. |
