Interconnection of power network and restructuring in power industry are raising increasingly more new requirements on power system operation and dispatch. The energy management system (EMS) in a traditional dispatch center has been changed a lot in configuration and functions. To adapt the EMS to the change, a concept of modern energy control center is proposed in this paper, which features high-level information, intelligence, integration and automation. The functions of the EMS will be developed from security only to coordination of security with economy, from local control to global and hierarchical control, from mainly off-line analysis to on-line analysis, from open loop control to closed loop control, from on-line steady state analysis to on-line transient state analysis. This paper describes the function extension of the EMS in a modern energy control center and predicts its prospects for development.
