Research on distributed new energy spot trading method based on blockchain Technology

With a large number of distributed new energy, electric vehicles, distributed energy storage, intelligent electrical equipment and other access to the power grid, new energy stakeholders are increasingly diversified and complex. The existing economic dispatching model of power grid has many problems, such as large error of renewable energy and load forecasting, low information transparency, high system security risk, high transaction cost, etc. As a new distributed database technology, blockchain technology has the characteristics of decentralization, transparency, credibility and traceability. It has a good fit with the power grid and can provide a distributed, safe and transparent information system for power grid dispatching and power trading. Therefore, a distributed new energy spot trading method based on weak centralized management is proposed, that is, using blockchain technology to store power trading information and settle accounts in the form of smart contracts.
