Research On Key Technologies Of Distributed Photovoltaic Transactive Enenrgy Based On The Blockchain

The popularization of green and low-carbon environmental protection concepts makes more and more enterprises and users accept and like distributed photovoltaic power generation,due to the advantages of using clean and renewable solar power,policy support,stable income,convenient installation,simple operation,and near-load side.It shows a good momentum of rapid growth year by year.However,with the rapid growth of the installed capacity of distributed photovoltaic power generation,problems such as the degree of marketization have gradually become prominent.The advancement of power system reform in recent years has led some domestic pilots to try to use centralized market-based transaction models to handle distributed photovoltaic transactive enenrgy.However,the existing management system and mechanism have a series of problems such as high transaction costs,asymmetric information,complicated processes,and difficult settlement when dealing with distributed photovoltaic transactive enenrgy.,which will hinder the enthusiasm of investors of the distributed photovoltaic power generation and users to a certain extent.Blockchain technology has the advantages of decentralization,information transparency,tamper-proof,traceability,low transaction cost and high security.Therefore.in order to solve the difficulties and pain points existing in distributed photovoltaic Transactive Enenrgy,This paper applies blockchain technology to distributed photovoltaic transactive enenrgy for research.irst of all.this paper discusses the 1901 document and its pilot in detail,and analyzes the shortcomings and shortcomings of the existing document and management platform.Secondly,the concept,classification and core technology of block chain are introduced in detail,and the advantages of block chain technology in distributed photovoltaic Transactive Enenrgy are analyzed.Finally,based on the actual data of distributed photovoltaic and users in a distribution network,this paper studies the causes and effects of trading deviation in distributed pv point-to-point transaction,and summarizes the characteristics of point-to-point transaction.On these basic studies.this paper delves into a series of key technologies of distributed photovoltaic Transactive Enenrgy based on the blockchain.including transaction system,transaction model,transaction process,transaction measurement,transmission fee.transaction settlement,transaction management system,system function composition,etc.This paper innovatively proposed the "one main and three auxiliary" trading system suitable for point-to-point trading,and designed the trading framework and trading process of the distributed photovoltaic point-to-point trading system.In addition,in view of the key technical problems of point-to-point transaction,the calculation methods such as transaction measurement,transmission fee and backstop service are proposed,and the design scheme of distributed photovoltaic Transactive Enenrgy management system based on block chain is proposed.More importantly,the Transactive Enenrgy platform of distributed photovoltaic based on block chain technology is realized,and an example is calculated and analyzed based on the actual data of a distribution network.The results show the effectiveness of the model and method in this paper.
