The Scheme Design For Body And Communication Subsystem OfVirtual Pumped Storage Prototype

Recent years,with thecontinual growth in demand for electricity and the excessive consumption fossilfuels,greenhouse gasemissionsand otherissues have become increasingly prominent. The introduction ofrenewable energycan effectively ease the contradictionbetween energyand environment.However, renewable energy has its own randomess and intermittence, a large scale of which connecting to the grid will reduce the reliability, thus energy storage technology research has become the key to solving the bottleneck problem of renewable energy.Combining the technologydevelopment ofenergy storage,theadvantages and disadvantages ofvarious energy storagetechnology are analysed and compared.A storagescheme combining pumped storage technology andcompressed air energy storage,namely virtualpumped storage technologyis introduced.A set of virtualpumped storagedesignscheme of experimentaldevice, based on theisothermal compressionprinciple and graded compressionprinciple is proposed.On this basis,the experimentaldevice is divided intohigh/low pressuretankscheme,hydraulicpressure pistonfacilityand water piston device. The selection of main equipmentof eachcomponentis given,and the operationschemeof each device is under the conditionof energy storageand generation.Theanalysisof devicesin the storage state andgenerating stateis presented respectively,a mathematical model was established and its calculationprocess is given,in the endthe feasibility ofdeviceoperation schemeis verified through an example.Based onZigBee technology andEthernet technology,a set ofvirtualpumped storagedesign scheme for communicationsystemexperiment equipmentis proposed.Using the sensor to collectthe required data,and upload it tothe console through thecommunication network,to realize real time acquisition andmonitoring of thedeviceparameters.Finally,the overall design scheme of the experimentaldeviceof energy storageof virtualpumpingproposedis summarized,and the deficienciesare analyzed, also the futureof virtualpumped storageimprovement directionkeyand subsequentexperimentaldevice systemresearch work is prospected.
