Description
Summary:The annual power balance calculation is of great significance for planning and future dispatching of power system. With the promotion of energy conservation and environmental protection, annual power balance research has became more important because it can effectively optimize resources on the annual time scale. Based on the previous research on the annual power balance of hydrothermal system, this paper proposes an mixed integer linear programming (MILP) model for annual power balance. In this model, the monthly load is represented by multiple typical daily load scenarios in that month. On the one hand, the calculation scale is reduced, as well as the calculation efficiency improved. On the other hand, the actual load is more realistically reflected. In addition, the model considers the temporal coupling between typical load scenarios. Finally, the results of the example verify the validity of the model.
