Research On Wind Power Energy Transaction Management Based On Ethereum

With the convenience of the smart grid in the application of wind power system,there are also defects that affect the security of wind power management rights and privacy of data leakage.Due to the decentralization of wind power systems,traditional centralized transactions cannot meet the demand for wind power in-place consumption.Management privileges and data security,as well as fast processing,are critical to wind power systems.They affect whether distributed transactions between the two parties can proceed smoothly.In view of the above problems,the contract management scheme of wind power network is adopted by using block chains,ethai fang,etc.Research and design management rights and data security of wind power system.Safe and fast storage processing combined with large data storage contract scheme for wind power sources.Both of them provide technical support for wind power trading schemes.The main research work is as follows.(1)The contract management scheme of wind power energy network is based on Ethereum.It should meet the security and processing speed requirements of the authority management and control of wind power nodes.It is Relied on Ethereum block technology to build intelligent contract.It is Relied on Ethereum block technology to solve the security protection problem of distributed network access control management in wind power energy system.First of all,It is based on the analysis of wind power network security management requirements.The mathematical model of security index is established for the control center and subordinate nodes when their authority is out of control.Secondly,It is based on the release platform of Ethereum smart contract.The Wind Power Contract Management(WPCM)is run according to the mathematical model of security index.The simulation results are compared with the communication parameters of a typical wind farm in northwest Europe.The research shows that the established wind power energy network security management scheme has the characteristics of high security and good robustness.The system has fast processing speed and meets the communication standard of offshore wind farm.(2)The big data storage contract scheme of wind power is based on Ethereum.It is limited by the lack of big data transmission and storage security in the future development of wind power equipment.The big data storage of wind power is based on IPFS.And the smart contract retrieval and storage scheme are based on Ethereum are proposed.The data of wind power system is stored and hashed by IPFS.Store State And Validate Algorithms(SSAVA)is used to ensure data storage efficiency and security.At the same time,the smart contract retrieval and storage scheme based on Ethereum is used to store the hash value as the retrieval chain.The Memory Efficiency Compensation Algorithm(MECA)is used to improve the storage and retrieval speed.The performance research shows that the established wind energy big data storage contract scheme has the characteristics of high security,large storage space and fast data processing speed.(3)Research on wind power energy trading scheme is based on Ethereum.In the face of the large number of transactions and the uncertain amount of transactions in the traditional management center,there are some defects,such as the high operating cost of facilities,the time difference of capital settlement,and the opacity of the transaction process.The wind power trading scheme based on Ethereum is studied.Firstly,it is difficult to realize the marketization of wind power generation and power purchase.Wind power cost and profit control algorithm and optimal power purchase algorithm are used to minimize wind power cost and optimal power purchase price.Then through the Ethereum trading office,according to the matching optimal algorithm to achieve the decentralized transaction of both sides.In this study,Ethereum builds smart contracts to achieve regional wind power cost control and wind power energy big data storage contracts.These have laid a foundation for the management and control mechanism of matchmaking transactions.The simulation results show that the research scheme has good management,controllability and efficiency.
