Distributed Energy Trading: The Multiple-Microgrid Case

Distributed energy, mainly composed of new energy, plays an important role in promoting the development of new energy. At present, the development of distributed energy is greatly hindered by imperfect trading platform and unstable output of new energy. Blockchain is decentralized, autonomous and requires collaborative management. Its own technical characteristics have the inherent advantages of reconstructing the energy system. The alliance chain in the blockchain is more suitable for building a distributed energy trading platform. The paper constructs a distributed energy transaction model based on alliance blockchain, studies the integration mode of blockchain and distributed energy transaction, and explores the application of blockchain in distributed transaction. The paper provides a new idea for optimizing and reconstructing the traditional distributed energy trading platform, and providing decision support for promoting distributed energy trading.

Aiming at the multi-agent, multi-mode and multi-rule characteristics of the distributed energy trading market,a distributed energy trading method based on blockchain is proposed. In view of the randomness and volatility of distributed energy, the use of the decentralized characteristics of blockchain technology meets the needs of distributed energy market transactions; in order to improve the reliability of the distributed energy transaction process, it is proposed to use smart contracts to separate the transaction and the communication process between the blockchain and the energy fund account; with the help of Ethereum’s “Raiden Network”, this “off-chain transaction” method, frequent and efficient transactions are carried out, realizing the “tripartite” of distributed energy producers, grid institutions and users “win-win” to promote the opening and healthy development of the distributed energy market.

Abstract The resilience of the power grid is taking a vital role in the energy supply and distribution process. But due to the rapid growth of integration of renewable distributed energy sources to the traditional power grid, the nature of the trading system is shifted from the centralized to decentralized or distributed manner. Blockchain is one of the most emerging security technologies that change the dimension of the financial and energy sector with openness and complete freedom. Blockchain implemented distributed energy trading promotes decentralized electricity markets. The physical system consists of the planning of the routing of energy from one place to another. A user can not send power to another customer in any severe outage or natural disaster in a traditional system. The user cannot participate in the trade globally. So in this proposed methodology, the connections of each customer to the central grid through several microgrids have been shown. In this work, an innovative approach in trading and finding a solution to a payment method is proposed. Ethereum blockchain-based smart contracts completed the entire trading system in automation mode in our proposed system. Any power outage at one place can be compensated by routing a new path of energy inflow from another active source, which enhances the system’s resiliency to a certain degree. While trading, no third parties will be engaged so that the transaction is efficient and fast.
