Research On Optical Storage Coordination Control Of Power Supply System In Data Center Based On Panama Power Supply

With the development of the digital age,the number of data centers has increased dramatically and its importance has become increasingly prominent.At present,the pace of domestic data center construction is speeding up,users demand higher and higher power supply,but the traditional data center power supply system covers a large area,low efficiency,high loss,high maintenance difficulty.According to the development of data center and the demand of users for power system,the problems of reducing space,improving efficiency and reducing maintenance difficulty are put forward.Panama Power is a new power technology suitable for power supply systems in data centers.Compared with the traditional power supply scheme,it can save the inverter link in AC Uninterruptible Power Supply(AC UPS)and is simpler than the power link of High Voltage Direct Current(HVDC)Panama power supply has the advantages of energy saving,environmental protection,less land occupation,high power supply reliability,and has great development prospects.Because the energy consumption of data center is large,its power supply mode is the key to achieve low carbon and energy saving.Solar energy is a clean energy,and will not be exhausted.Connecting new energy to the power supply system of data center can reduce the burden of urban power supply.In this context,this paper will connect photovoltaic to the power supply system in Panama,but the intermittent solar power system fluctuations must be resolved.In this paper,a control strategy of light storage power fluctuation based on Panama power supply system is proposed to stabilize the photovoltaic power supply system after the photovoltaic power supply system is connected to data center.For the content of this study has the following key points:First of all,this paper analyzes and summarizes the advantages and disadvantages of AC UPS power supply,HVDC power supply and Panama power supply through the study of existing programs at home and abroad,and determines the research object:Panama power supply system.Secondly,three typical topologies of data center are studied,and the topological structure of power supply system in Panama is determined through discussion and analysis.Based on the Panamanian power supply system,the operation strategy of Panamanian power supply system,photovoltaic system and energy storage system is studied,and the models of Panamanian power supply system,photovoltaic system and energy storage system are built by PSCAD/EMTDC.Finally,the influence of the PV system on the power supply system is analyzed,and a coordination control strategy of the PV system based on the PSCAD/EMTDC simulation software is proposed to verify the correctness and feasibility of the strategy.In this paper,the power supply system of Panama,which is oriented to the data center,is studied,and the power fluctuation brought by the system is discussed in detail.
