[PDF][PDF] A MILP-based formulation for thermal-wind-BESS unit commitment problem considering network power loss
Unit commitment is one of the most critical problems in power system operation. The
objective of the unit commitment problem is to determine the start-up and shut-down
schedule of generating units for a given planning horizon with the aim of maximizing social
welfare while satisfying the load demand and meeting the technical and security constraints.

Unit commitment is one of the most critical problems in power system operation. The objective of the unit commitment problem is to determine the start-up and shut-down schedule of generating units for a given planning horizon with the aim of maximizing social welfare while satisfying the load demand and meeting the technical and security constraints. This paper proposes a model based on Mixed-Integer Linear Programming (MILP) as a way of dealing with the unit commitment problem of thermal-wind-BESS integrated systems considering network power loss. This MILP based-formulation is developed from the Mixed-Integer Nonlinear Programming (MINLP) model by linearizing the power loss. The proposed model is validated using the power transmission system of the IEEE RTS 24-bus. The calculation results reveal that the power loss makes a considerable impact on the commitment of production units, the actual power output of the committed generating units and scheduled storage power.
