Research And Application Of Virtual Power Plant Operation Decision-Making Method Considering Response Characteristics

With the transformation of China’s energy structure and upgrading of its industrial structure,the proportion of new energy installed capacity is increasing year by year,and the level of electricity consumption continues to grow.Due to the random volatility of new energy generation and other factors,relying solely on the flexible resources of traditional power generation and grid sides is difficult to ensure the safe and stable operation of the new power system.It is urgent to widely aggregate various resources into power balance scheduling.Virtual power plants rely on advanced communication technology to aggregate multiple types of flexible and adjustable resources,enabling internal collaborative optimization and control,external packaging to participate in the power market,and low-cost and efficient aggregation of massive flexible resources to respond to power balance needs through market-oriented methods,solving the problem of power balance.Firstly,this article introduces the basic theory of virtual power plants participating in interactive regulation of the power grid,and analyzes the industrial chain and business model of virtual power plants;Summarized and sorted out the policy basis and practical experience of typical virtual power plant projects at home and abroad,and analyzed the cases of virtual power plants participating in the spot market;Based on research on national policies,energy and power system development,and power market construction,propose development suggestions and vision for virtual power plants.Secondly,this article analyzes the response characteristics of the virtual power plants and the various physical entities that it aggregates,and analyzes the overall external characteristics and control mode of the virtual power plant.The production rules,operating mechanisms,load characteristics,response characteristics and response capabilities of adjustable resources are analyzed.Based on the response capacity of various types of flexible resources of virtual power plants,the operation recommendations of virtual power plants are proposed.Finally,this article studies the business model of virtual power plants to participate in the multi-time-standard power market,analyzes the model of virtual power plants to participate in the multi-time-standard power market through aggregating flexibility and adjustable resources;followed by designing the mechanism and business of virtual power plants to participate in the power market and business Model;established a market declaration strategy optimization model for virtual power plants to participate in the decision-making decision-making decision-making decision-making decision-making decision-making of the power spot market,and give corresponding constraints.In order to solve the decision-making model of virtual power plants to participate in the electricity spot market operation,it has been designed and developed a hybrid integer planning algorithm based on the configuration of the virtual power plant response characteristic parameter,and uses the SCIP solution to solve it.By analyzing the example analysis,it has proved that through optimizing the operating decision-making of virtual power plants,the profitability of its participation in the power market based on response regulation is quantified,and the key factors affecting the operation decision-making of virtual power plants are analyzed.Planning suggestions.
