Embodiment
[0071] The present invention proposes a virtual power plant optimization scheduling method considering demand response and carbon trading. The implementation process includes the following detailed steps:
[0072] Step 1. Count the number of distributed power sources (such as gas turbines, wind turbines, and photovoltaic generators) in the virtual power plant, as well as the number of controllable loads that can participate in demand response, such as electric vehicles and water storage air-conditioning systems;
[0073] Step 2. Predict the output of wind power and photovoltaic units in the virtual power plant and the rigid load in the power system on the next day;
[0074] Step 3. The energy management system of the virtual power plant accepts the recently declared information of the electric vehicle owner, which specifically includes: the grid connection and off-grid time of each electric vehicle, the estimated initial battery state of charge and the expected off-grid state o...

The invention discloses a virtual power plant optimization dispatching method considering demand response and carbon trading. The invention includes the following steps: counting the number of distributed power sources in the virtual power plant and the number of controllable loads of electric vehicles and water storage air-conditioning systems participating in demand response; counting the output of wind power and photovoltaic units in the virtual power plant and the output of the power system in the next day. Rigid load is forecasted; the energy management system of the virtual power plant accepts the current declaration information of electric vehicle owners; the energy management system of the virtual power plant establishes the virtual power plant simultaneously based on the current forecast information, electric vehicle declaration information and price information of the power market and carbon trading market. Participate in the optimal dispatch model of the power market and carbon trading market; solve the optimal dispatch model and obtain the day-ahead optimal dispatch plan of the virtual power plant. The present invention gives full play to the advantages of demand response resources in peak shaving and valley filling, and can also effectively reduce carbon emissions of the power system.
Description
Technical field [0001] The invention belongs to the field of power system optimization and dispatching, and in particular is a virtual power plant optimization dispatching method that considers demand response and carbon trading. Background technique [0002] In order to solve the shortage of fossil energy and the environmental pollution problems caused by the burning of fossil fuels, clean renewable energy generator sets have been increasingly widely used; in order to alleviate the increasing demand pressure on the load side of the power system, the application of controllable loads has gradually received attention. . With the continuous increase of renewable energy generators and controllable loads, new problems such as the fluctuation of generator output and the uncertainty of source-load power balance have gradually emerged, bringing new challenges to the safe and economic operation of the power system. Based on this, the concept of "virtual power plant" came into being...
