Uso da blockchain do Ethereum para a realização de leilões de energia elétrica através da criação de ferramenta WEB

Abstract

The energy sector as a whole has been experiencing a deregulation movement in recent years with increasing distributed generation. The entry of new agents makes more complex distribution networks and must be accompanied by mechanisms that facilitate their operation, as well as encourage the insertion of small producers. Currently, the electrical system structure, besides being complex, is bureaucratic and hinders the entry of prosumers, in addition to a consumer's treatment as a passive agent of the system. In this scenario, the energy utilities are mandatory in all processes, bringing little autonomy to the network. This paper presents a tool that uses Blockchain technology, which shows its disruptive power in various sectors, being known best for implementing an encrypted Bitcoin, creating a WEB application responsible for making prosumer-to-consumer energy auctions without interference from intermediaries. The project consists of a WEB application developed in HTML, CSS and JavaScript, with MySQL database, which through Web3.js library, integrates with an intelligent contract in Solidity language, using Ethereum's native IDE Remix to hold daily power auctions. There are three houses that simulate photovoltaic solar production and set minimum prices for energy acquisition. Thus, the consumer can access the application on the internet and check the sale terms for each house to make offers in Ether (Ethereum's cryptocurrency) for the energy offered. A demo is performed in which five bids placed in the three houses and the auction results are presented and analyzed.
