Problems solved by technology

[0003] However, most of the current research on automatic demand response simulation technology for power systems is to design multiple demand response control strategies based on different optimization objectives, such as the lowest user consumption and the highest user comfort, and to verify them through pure software simulation, or simply for a certain Research on regulation potential and strategies of demand response resources such as heating, ventilation and air conditioning (HVAC) or electric vehicles; it is not connected to actual user electricity terminals to verify the specific implementation effect of demand response, nor can it simulate electricity demand response The implementation process of the automatic demand response business in the system and the corresponding power flow changes in the power supply area where the user is located during the process

Furthermore based on semi-physical simulation technology, the response effect in an application process can be simulated in participating the demandresponse service by means of actual equipment or physical simulation equipment. Furthermore further verification is performed on feasibility of related scheme, plans, strategies and the like in the simulation system.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a demand response digital-physical hybrid simulation method and system. Background technique [0002] The implementation of the new round of power reform has accelerated the development of power demand side management, and demand response (DR) refers to the response of users to prices or incentive signals, and changes the normal power consumption pattern, so as to realize the optimization of power consumption and the system The comprehensive optimal allocation of resources is an important technical means of power demand side management. Its development has greatly promoted the optimal allocation of resources on the demand side, the consumption of new energy, and the realization of peak-shaving and valley-filling. However, due to the current problems that the demand response mechanism cannot meet the diversified market needs, single demand response resources, l...
