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.
