Research On Group Consensus Of Distributed Energy Dispatching Control Based Event-Triggered

In order to ensure the sustainable development of human beings,more and more people are turning their attention to distributed energy sources that integrate clean energy.However,due to the unstable power generation,small capacity,it is difficult for the centralized control of traditional power grids to regulate them.Therefore,the economic regulation of distributed energy is being transformed from centralized distributed transitions.In the economic regulation of distributed energy,we can regard controllable power equipment such as power generation unit as an agent,so the multi-agent consensus algorithm can be applied to the economic regulation algorithm of distributed energy.This paper mainly studies the application of event-triggered consensus algorithm and group consensus-based algorithm in the regulation of distributed energy.The specific work is as follows:(1)The event-triggered consensus algorithm is applied to solve the economic regulation problem of distributed energy.This paper aims to minimize the cost of power generation,on the premise of satisfying the balance of supply and demand in the system,an event-triggered consensus algorithm is designed.The algorithm can ensure that the incremental cost of each power generation will eventually converge to the optimal value,and the event-triggered strategy used can reduce the number of times of exchanging information with neighbor nodes to save communication bandwidth.(2)Considering that when the number of distributed energy resources is large,it is difficult to make the incremental cost of all power generation units converge to the same target value.This paper proposes to apply the group consensus algorithm to the economic regulation of distributed energy resources.The algorithm can make the incremental cost of each power generation unit converge to its own optimal value by grouping on the premise of satisfying the balance of power demand.Finally,the effectiveness of the algorithm is verified through three simulation scenarios.(3)Finally,the event-triggered mechanism and grouping consistency are applied to the economic regulation of distributed energy.The algorithm can not only make the incremental cost of the power generation unit converge to its own group,at the same time,the time-triggered strategy can reduce its communication frequency.Through the simulation of different scenarios,the effectiveness of the group consensus algorithm based on the event-triggered mechanism in the economic regulation of distributed energy is verified.
