Problems solved by technology

[0006] However, in the existing research, the joint scheduling of demand-side resources such as electric vehicles and air-conditioning loads and distributed energy sources such as wind power and photovoltaics is not combined, and there is no combination of day-ahead / real-time two-stage scheduling problems, which makes the spare space for day-ahead reporting difficult. Evaluation, in the scheduling process, the errors of wind power and photovoltaic forecasts, and the user's travel needs and temperature comfort requirements are not fully considered
