Research On Collaborative Scheduling Method For Energy Internet

With the global energy crisis and the increasingly serious environmental pollution,the Energy Internet(EI)has attracted the attention of governments and scholars.The Energy Internet is dominated by electricity,coupled with natural gas,wind,solar and other energy forms,covering energy production,transmission and consumption.However,with the access of large-scale distributed renewable energy,the reasonable and effective operation and scheduling management of various energy sources in the Energy Internet has become a key issue in the research of the Energy Internet,which is of profound significance to its research.The purpose of energy dispatching is to realize largescale consumption of renewable energy,reduce energy waste,and ensure the stable and efficient operation of Energy Internet.In this dissertation,the single-domain and multi-domain Energy Internet is taken as the research object,and the single-domain internal energy cooperative scheduling and multi-domain energy cooperative scheduling problems in the Energy Internet are studied.The following tasks are mainly completed:(1)In view of the single domain energy scheduling optimization problem in the Energy Internet,a single domain energy collaborative scheduling optimization model is established by comprehensively considering the load balance,power supply cost,power supply reliability and environmental protection factors.(2)An intensity pareto algorithm based on adaptive grid mechanism and penalty mechanism is proposed for single domain energy cooperative scheduling model.The improved intensity pareto algorithm is applied to the collaborative optimization of single-domain energy dispatching in the Energy Internet to solve the problem of single-domain energy dispatching.The experimental results show the effectiveness and rationality of the algorithm and the model.(3)Based on the single domain energy collaborative scheduling,the multi-domain energy collaborative scheduling optimization of the Energy Internet is further studied.By introducing cooperative game theory,a multi-domain energy cooperative scheduling method based on cooperative game is proposed.This method can solve the problem of multi-domain energy collaborative scheduling in the Energy Internet,realize the multi-domain self-organization as a mutually disjoint alliance in the Energy Internet,avoid vicious competition,and maximize the interests of each region.
