High proportion of new energy integration and slowing growth rate of thermal power installation will continuously compress the safe and economic space for reliable scheduling on the power generation side,and guide the coordinated development of the power system’s“source load”is an important way to promote energy transformation. Firstly,load resources are divided into three categories：real-time dispatchable load,guided elastic load,and emergency regulation load,and are defined and modeled separately. Secondly,based on the actual security network requirements for regulation,propose a regulation information exchange method and architecture for different load resources. Next,based on the requirements of regulatory business scenarios,market-oriented compensation methods and evaluation models are constructed for three types of load resources：grid balance reserve,real-time load regulation,and orderly electricity consumption with extreme supply-demand imbalance. Finally,quantitative analysis of compensation methods is conducted through numerical examples,providing reference for subsequent participation of load resources in the market.
