| "13th Five-Year" period is the decisive period of the construction of a well-off society in China,comprehensively deepen the reform period.And electricity is the relationship between the people's livelihood and basic industries,power supply and security related to national security strategy,related to social and economic development of the overall situation.National Development and Reform Commission released the "power development" thirteen five "plan",covering nuclear power,hydropower,coal,gas,wind power,solar power,transmission and distribution network construction and other aspects of the development of the power industry Provided a basic follow.However,the development of new technologies such as energy Internet will make the power system physical structure,information exchange mode,power market operation mode change,to the traditional power system planning and operation of the work has brought new challenges.In this paper,a set of multi-energy complementary operation optimization model for energy Internet is established.The optimization strategies of power supply side and user side are discussed respectively.The dynamic simulation of the proposed model is carried out in combination with the actual case.Optimize the operation related work to provide new ideas,new methods.The main work of this paper is summarized as follows:(1)Review the domestic and international demand response research related literature and results,combing the evolution of the energy Internet and the impact of traditional power systems.First,the core meaning,typical and characteristic and basic structure of the energy Internet are introduced.Then,combing the evolution of the energy Internet,trading patterns and the main development significance.Finally,the paper analyzes the direct and indirect effects of the energy Internet on the power system,and provides a comprehensive research background and theoretical basis for carrying out the multi-energy complementary development strategy for the energy Internet.(2)The optimization model of collaborative operation of the integrated environment for the energy and the environment is established.The output power model of different types of units is designed,and the efficiency of the system is maximized,the lowest cost of the energy is minimized and the load fluctuation rate is minimized as the objective function.Considering the balance of load supply and demand,operation and system backup and other constraints,the establishment of the landscape fire and water storage integrated system operation optimization model.(3)Constructing a distributed energy integrated virtual power plant scheduling optimization model for energy Internet.In order to analyze the influence of the randomness of clean energy output on the virtual power plant operation,the two-stage optimization theory is used to set the prediction power of the clean energy generation as a random variable,and the scheduling optimization model is established.The ultra short term or real-time prediction power is realized as a random variable,Scheduling optimization model before establishment.(4)A multi-objective operation optimization model for clean energy aggregation multi-energy complementary system for energy Internet is proposed.Considering the diversified energy demand of the end user,the multi-energy complementary system composed of the integrated power source system,the auxiliary system of the cogeneration system and the auxiliary heating subsystem,and put forward the system optimal operation strategy and performance evaluation index,choose the optimal energy performance,environmental performance and minimum carbon emissions as the operational target,and establish a multi-objective operation optimization model and solving algorithm for multi-complementarity system. |
