基于BaaS平台的微网用户端对端电能交易方式研究

随着电力市场化改革的推进，微电网或拥有分布式发电的用户作为售电主体，被允许参与电能市场交易。但现有条件下的电能交易面临着缺乏信任和中心化的问题，区块链技术作为一种全新的分布式加密方式，对实现用户之间公平、点对点、实时、去信任的能量交易具有重要意义。文章首先介绍已有的区块链电能交易项目，分析对比了可供开发者使用的区块链即服务（blockchain as a service，BaaS）平台；然后对应用区块链技术的端对端电能交易网络和交易算法进行设计，分析了区块链即服务平台的应用过程；最后以一园区3个分布式光伏用户的运行实例，说明区块链技术下微网电能交易去中心化、透明化、难以篡改的特点，及其在促进微电网安全高效运行，社会利益最大化的有效性。

Research on Peer-to-Peer Energy Transaction at User-side for Microgrid Based on BaaS Platform

With the reform of electricity market， micro-grid or users with distributed generation are allowed to participate in electricity market transactions as the main power sellers. However， under the existing conditions， energy transaction is faced with the problem of lack of trust and centralization. Blockchain technology， as a new distributed encryption method， is of great significance to realize fair， point-to-point， real-time and untrusted energy trading among users. Firstly， this paper introduces the existing blockchain energy trading project， and analyzes and the Baas platform available to developers. Then the P2P energy transaction network and transaction algorithm using blockchain technology are designed， and the application process of the blockchain Baas platform is analyzed. Finally， the operation examples of three distributed PV users in a park are used to illustrate the decentralization， transparency and hard to falsify of the microgrid energy transaction under the blockchain technology， and to promote the safe and efficient operation of the microgrid and the effectiveness of the greatest social benefits.
