Research On Information Layer And The Control Algorithm Of Service Layer Of Energy Router

As the human society’s demand for diversity of energy increases greatly,the traditional single energy network cannot provide diversified functions to serve users.In order to adapt to the mutual transformation,storage and coordinated operation of various energy systems in the new era,the energy Internet arises at the historical moment,and the energy router is the core device of the energy Internet,which is used to realize the optimal operation of many kinds of energy.This paper mainly studies the information layer and the control algorithm of service layer of the energy router and solves the scheduling problem of the multi-energy form of the energy router.Components of multi-energy Energy Router are constructed and the mathematical model is established.The information layer of energy router is constructed and designed.This paper also studies the multi-objective optimization algorithm of the service layer of the energy router.Combined with the information of the information layer,the improved NSGA-Ⅱ algorithm is used to carry out the energy scheduling of the entire energy router,and an example of simulation experiment is set up for verification.Specific studies are as follows:Firstly,based on the research and demonstration project of key technologies of energy router in multi-energy form,this paper proposes an energy router with energy layer,information layer and service layer as the framework and describes the relationship among them.Then,starting with the composition of the information layer of the energy router,the architecture of the information layer is constructed.And the human-computer interaction-cloud service module,human-computer interaction interface,centralized control module and a new parallel communication protocol for low-level information interaction are designed for the information layer.For the hardware of centralized controller,the circuit design of power module,communication module and data sampling module is introduced and analyzed in detail.For the communication at the bottom of the information layer,this paper proposes a new parallel communication protocol,analyzes the working principle,and carries out the effectiveness of experiment.The experimental results show that the parallel communication protocol can run effectively,which lays a foundation for the implementation of future projects.Afterwards,the service layer of different functional control algorithm is considered,this paper use the energy router service layer of multi-objective control algorithm as the breakthrough point.In view of shortcomings of the NSGA-Ⅱ in distribution and global convergence,this paper proposes the corresponding improved strategy,the improvement of the crossover rate,mutation rate and the crowded distance,and uses the test function to test.Test results show that compared with traditional NSGA-Ⅱ algorithm,the improved NSGA-Ⅱ algorithm can get better Pareto front.At the same time,performance is improved through evaluation indicators in the distribution and the global convergence.Finally,combined with the project energy router information layer and improved the NSGA-Ⅱ multi-objective optimization algorithm of service layer,the mathematical model housed in the form of unit energy router is established.Aiming at the operating cost and environmental cost of the whole energy router,this paper carries out the energy scheduling of the multi-energy energy router,and verifies the effectiveness and superiority of the improved algorithm through simulation,and obtains the output of each equipment of the energy router,and analyzes it.
