Abstract

Abstract:

In the “dual carbon” campaign, adjustable load is an emerging adjustable resource for power grids. 13 power industry standards in the series of “Technical Specifications for Adjustable Load Grid-connected Operation and Control” was organized and carried out by the National Power Transmission Center relying on SAC/TC446 National Power Grid Operation and Control Standards Committee. Based on the standards, in this paper, the overall thinking, positioning and boundary of the 13 adjustable load standards were analyzed by reviewing the recent studies of domestic and foreign adjustable load standards. Then, the research focus and key technologies of the 13 standards were proposed. Finally, combined with typical pilots of load regulation and load participation in the market, the actual situation of application of the standards was analyzed, and the effectiveness of the standard was verified. This work can provide strong support for the improvement of adjustable load regulation capability.

Key words: adjustable load, regulation and control capacity, load assessment, index system, industry standard
