| With the rapid advancement of the carbon peak and carbon neutrality goals,the power system is undergoing profound changes.In the current power system,a large number of distributed energy sources,energy storage devices,and controllable loads are being rapidly deployed.How to provide green and efficient communication access services and aggregation services for these devices with geographically diverse locations has become a key research focus.Virtual power plant technology,as an important means of solving the problem of new energy consumption,plays an important role in the new power system framework.Therefore,the importance of information and communication technology research in the virtual power plant scenario is self-evident,as it will directly determine whether various types of new energy can be stably and efficiently accessed to the power grid,thereby becoming the key to solving the problem of new energy consumption.The 5G Electric Power Dedicated Network is a wireless communication access network designed for the power industry,characterized by high bandwidth,low latency,high reliability,and high security.It can provide support for communication access to medium and low voltage distribution networks and fiber-optic blind spot communication coverage in virtual power plants.Although 5G Power Grid has excellent communication performance,its high energy consumption cost is not widely accepted at this stage and has become an important problem that urgently needs to be solved.To address the high energy consumption cost of 5G Power Grid,this paper adopts C-RAN(CloudRadio Access Network)as the access network architecture.C-RAN divides the base station into two parts:BBU pool and RRH,and adopts a wireless network architecture connected by optical fibers.It has the characteristics of centralized resources and flexible deployment,and is considered an effective method to solve the problem of high energy consumption cost in 5G networks.Based on this,this paper conducts subsequent research on 5G C-RAN communication energy efficiency optimization and 5G C-RAN communication system renewable energy consumption.When using the 5G C-RAN architecture,communication resource scheduling and allocation are typically important issues.This paper proposes a high-efficiency communication resource allocation method based on the A3 C(Asynchronous Advantage Actor-Critic)algorithm for the 5G C-RAN communication resource allocation problem in virtual power plant scenarios,and constructs corresponding mathematical models and constraints.This method optimizes parameters such as user access,base station selection,and power allocation to achieve maximum efficiency in communication resource utilization and improve the energy efficiency of virtual power plant communication systems.Simulation results demonstrate that this method can effectively improve the energy efficiency of communication systems and ensure that the service quality of communication systems meets constraint conditions.Compared with the optimal communication efficiency obtained by exhaustive search,the energy efficiency of this method can reach 96.7%of the optimal communication efficiency,and it has significant performance advantages over other comparison algorithms.To address the issue of renewable energy integration in 5G C-RAN communication systems,this paper proposes a method for maximizing the renewable energy consumption rate of base station energy storage scheduling,and constructs corresponding mathematical models and constraints.This method is based on the Dueling DQN(Deep Q-network)algorithm and considers base station energy storage as a "reservoir" of renewable energy.By optimizing the scheduling of base station energy storage,the 5G C-RAN communication system can maximize the integration of renewable energy and effectively reduce the energy consumption costs of the 5G electric power dedicated network.Simulation results show that this method can effectively improve the renewable energy integration rate of the 5G C-RAN communication system and reduce its dependence on traditional energy sources.Compared with the renewable energy integration loss of the optimal solution obtained by exhaustive search,the renewable energy integration loss of this method is only 28.8%higher than the optimal solution,and it has significant performance advantages compared to other comparative algorithms.In summary,the research on the energy efficiency optimization and renewable energy integration of the 5G C-RAN communication system effectively reduces the energy consumption costs of the 5G electric power dedicated network from two different perspectives,while ensuring the efficient and stable operation of the communication system.This provides strong support for the development of virtual power plant technology in the information and communication field and offers powerful support for the communication access and efficient aggregation of renewable energy. |
