Demand side management worth evaluation under generation system planning framework

Demand side management (DSM) can help reduce demand of the system, resulting in less generating capacity and less total production cost in the future. Generally, each DSM activity, e.g., replacing old with new higher efficiency equipment, has its own cost. Its worth in the system may be used as one of the decision components. Therefore, the methodology in evaluating the DSM worth under the framework of long-term generation system planning will be proposed in this paper. With the obtained results, the system planners will be able to select DSM programs more appropriately.
