Abstract

Abstract:

To address the impact of different numbers of electric vehicles (EVs) and uncertainty of wind power output on power grid dispatching,the day-ahead dispatching interval optimization model with the uncertainty of wind power output and EVs is established.First,the uncertainty of wind power output is represented by the interval number.The interval optimization model of day-ahead dispatching is established by considering the different numbers and operation constraints of EVs.Then,the interval optimization model of day-ahead dispatching is converted into two sub-models for solving.Finally,the proposed model is tested and analyzed by using the 10-unit system.The accuracy and economy of the proposed model are verified through the analysis of arithmetic cases.

Key words: electric vehicles, day-ahead model, optimization, interval
