In order to promote the development of smart and lean dispatching, the new smart control center constantly introduces new technology to deal with the challenge. The paper systematically introduces the concept of time stamped measurements for steady state grid and then proposes a key technical scheme for application of time stamped measurements for smart control centers. Finally, some key technologies including unified application support platform integrated with time sequence database, supervisory control and data acquisition (SCADA) supported by time stamped measurements, state estimation based on time stamped measurements and open data platform based on time sequence database of the scheme are studied. The research result has been applied in pilot projects of smart grid dispatching technology support system in Suzhou City and Jiangsu Province, respectively.
