摘要/Abstract

摘要：

为解决需求侧响应过程中各个主体不互信而导致成本高、沟通不及时的问题,在梳理区块链通用技术原理基础上,给出区块链需求侧响应方案的整体架构、交易流程、数据上链设计、智能合约设计、网络搭建方案、共识机制等,并从多个维度开展效益分析,为既利用中心化管理优势又提供非中心化存证及监督功能提供了思路。仿真搭建了由7个节点组成的需求侧响应联盟链网络,验证架构和模型的可行性,并给出了界面设计示例;基于搭建需求侧响应区块链应用的效益函数,以河南省需求侧响应场景为例,说明了区块链技术应用于需求侧响应技术的经济性和可行性。

关键词: 需求侧响应, 区块链, 系统设计, 效益分析

Abstract:

In order to solve the problems of high cost and untimely communication caused by the lack of mutual trust among various subjects in the process of demand response, on the basis of combing the general technical principles of block chain, this paper presents the overall architecture, transaction flow, data chain design, intelligent contract design, network building scheme and consensus mechanism of the blockchain demand response scheme, and carries out benefit analysis from multiple dimensions. It provides a train of thought for not only making use of the advantages of centralized management, but also providing non-centralized deposit certificate and supervision function. The simulation builds the corresponding alliance chain network on the demand composed of seven nodes, verifies the feasibility of the architecture and model, and gives an example of interface design. By building the benefit function of demand response blockchain application and taking the demand response scenario in Henan as an example, this paper demonstrates that the application of block chain technology to demand response is economic and feasible.

Key words: demand response, blockchain, system design, benefit analysis
