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.

According to the principle of integrated resource planning (IRP), describes the know-how in CEP, such as target setting, estimation of available resources, load forecasting, scheme of energy system, determination of virtual power station, implementing stricter energy efficiency standard, and full process management etc.

If the integrated resource planning has the resources of the supply-side and demand-side in the planning process considered at the same time, it can realize the objective of minimizing the total cost.

However, DC could not be used in integrated resource planning, since system electrical demand is divided into several classes due to different reliability require-ments.

Based on the integrated resource planning(IRP) for cross-regional transmission,the issue was studied on how to involve emission-reduction costs into IRP in order to encourage low-emission generation units to more actively participate into power planning.

Based on the current situation of electric power planning and generation and transmission resources in China,a new integrated resource planning(IRP)method,which takes the inter-regional transmission into account,was proposed.
