摘      要：With the development of renewable energy and the changes in the characteristics of power grid,it is becoming increasingly difficult to balance power supply and demand in space and *** addition,the requirement for improved dispatching capability of power grid is ***,the potential of flexible load dispatching should be realized,which can promote the large-scale consumption of renewable energy and the construction of new power *** on the analysis of existing load dispatching studies and the differences in the characteristics of domestic and foreign load dispatchings,a technical architecture and several key technologies are proposed for load resources to participate in power grid dispatching under the new situation,i.e.,the autonomous collaborative control system of load *** system implements the multi-layer coordinated control of main,distribution and micro grids(load aggregators).Adjustable load resources are aggregated through an aggregator operation platform and connected with a dispatcher load regulator platform to realize real-time data interaction with dispatching agencies as well as the monitoring,con-trol,and marketing of *** supports the load resources to participate in network-wide dispatching optimization via continuous power *** key technologies such as the control mode,load modeling,dispatching strategy,and safety protection are also *** the closed-loop control of orderly charging piles and energy storage clusters in the North China Power Grid,the feasibility of the proposed architecture and key technologies is *** route has successively supported multiple adjustable load aggregators to partici-pate in the ancillary services market of North China Power Grid for ***,the technical challenges of load resources participating in power grid dispatching under the dual carbon goals are discussed and prospected.
