| Abstract: | This paper focuses on the problem of coordinated load control of provincial and regional power grid under the traditional artificial mode, when the high-power loss occurs in the receiving-end power system after the bipolar block of ultra-high voltage direct current(UHVDC)transmission system or major accidents. A concurrent automatic load control system is proposed for the two-level decomposition-coordination between provincial and regional power grids. The overall structure of the system, the implementation scheme of key technologies and the safety mistake preventing technology are provided. The coordinated load control system of provincial and regional power grid is set up to realize the batch control of load dispatching information interaction and closed-loop control between provincial and regional power grids. Combined with the engineering practice in the relevant dispatch center of the UHV sending-end and receiving-end, the practical application effect of the proposed control system is introduced. |
