MILP formulation of the UC-problem with boundary conditions on the autonomous forecasting horizon

Abstract

The intervals for determining the variables in the standard MILP-formulation of the UC-problem are analyzed. The need to take into account the state and load values in the pre-forecast and post-forecast time has been established. The suitability of the standard MILP-formulation of the UC-problem, problem with initial conditions, for solving dispatch control problems and the unsuitability of such a formulation for solving the generation capacity planning problems is shown. The standard MILP-formulation of the UC-problem on the cyclical forecasting interval is proposed. The suitability of the proposed MILP-formulation of the UC-problem for its application in the problem of planning the development of the generation capacity of power systems with a large share of RES is shown.
