摘要:

中国可再生能源规模的快速增长使得财政直补的压力增加,可再生能源配额制度(简称配额制)和可交易绿色证书(简称绿证)能够以市场化的方式对可再生能源进行补贴,或成为支持其产业发展的重要手段。中国绿证市场尚处于起步阶段,仍缺乏流通机制的系统性设计。文中提出绿证的双边交易机制,并根据配额制的需要设计了涵盖核发、交易、核查的绿证流通全生命周期。在绿证的全生命周期中,不同主体需要追踪并异步更新其状态。随着绿证市场规模增长,数据账本的一致性和安全性问题亟待解决。为此,文中提出了基于超级账本Fabric1.1的绿证交易平台解决方案,搭建了区块链底层网络环境和应用环境,开发了绿证交易必需的功能和接口,并依托中国珠海市“互联网+”智慧能源示范项目开展了实地验证。目前,共有十余家新能源发电企业和三十余家电力用户注册参与,完成模拟交易一百余笔,验证了平台的实用性和完备性。

Abstract:

With the rapid development of renewable energy in China, the pressure on direct financial subsidies is increasing. The renewable portfolio standard (RPS) and tradable green power certificate (GPC) provide a market-oriented way to subsidize the renewable energy, which makes it a promising option to support the renewable energy industry in China. Chinese GPC market is still in the early stage and lacks a systematic design of circulation mechanism. This paper proposes a bilateral trading mechanism of GPC and designs the full life cycle of GPC circulation covering issuing, trading and inspection considering the needs of RPS. In the full life cycle of GPC, different entities need to track and update their status asynchronously. With the growth of GPC market, the consistency and security problems of the data ledger need to be tackled. Therefore, this paper proposes a solution for GPC trading platform based on Hyper-ledger Fabric1.1. The basic network and application environment of blockchain are built, and the functions and interfaces necessary for the trading are developed. The field verification is conducted based on “Internet Plus” Smart Energy Demonstration Project in Zhuhai, China. So far, more than 10 renewable generation enterprises and more than 30 power consumers have registered, and more than 100 simulated transactions have been completed, which verifies the practicability and effectiveness of the platform.
