The invention discloses a user adjustable load resource demand response method and system based on a virtual power plant. The method comprises the following steps: collecting and obtaining a user to be investigated according to an industry attribute and an electrical load of each user; identifying a to-be-investigated user with load adjustable equipment as a user participating in power demand response, and collecting adjustable load resources of the users; establishing an adjustable load technical economic model based on marginal cost, and establishing a capacity model of the maximum adjustable load based on safety constraints; therefore, an electric power real-time demand response adjustment algorithm model is formed; and when the demand response item is started, the operation state and the adjustable load resource of the adjustable load equipment of each user are taken as input data, and the power real-time demand response adjustment algorithm model is utilized to calculate the load regulation and control index of each user and carry out load regulation and control. According to the method, the power peak load is reduced, economic and reputation loss caused by orderly power utilization of the power grid is avoided, the maximum load of equipment at the peak load is reduced, and the operation capability of the power grid is improved.
Description
technical field [0001] The invention belongs to the technical field of virtual power plants participating in load resource demand response, and in particular relates to a user-adjustable load resource demand response method and system based on virtual power plants. Background technique [0002] A virtual power plant is a kind of coordination and optimization of DERs, such as DG, energy storage systems, controllable loads, and electric vehicles, through advanced information and communication technology and software systems, so as to participate in power supply coordination and management of power markets and grid operations as a special power plant system; the core of the virtual power plant concept can be summarized as "communication" and "aggregation". The key technologies of the virtual power plant mainly include coordinated control technology, smart metering technology and information communication technology; The operation of the electricity market and the auxiliary serv...
