Brief introduction of integrated resources strategy planning

The electric power deregulation has led electric power enterprises very difficult to do integrated resources planning(IRP) because generation, transmission and distribution were to be unbundled. Without IRP, DSM has lost its theory fundament. However, with the pressure of climate change and environment pollution, DSM has been promoted as a tool for energy saving and emissions reduction. Integrated resources strategy planning(IRSP) is studied in this paper as the expansion of IRP through nation-layer. Then by comparing IRP with IRSP, the basic concept and implementing steps of IRSP are discussed. IRSP can be the theory fundament of DSM.
