Effectiveness evaluation on energy trading systems taking blockchain technology

Abstract

Abstract:

Clean energy-based distributed energy has become an important part of China's energy transition and new power system construction. Since traditional energy transactions mostly take single trading mode and centralized operation and management mode， the demands for decentralized energy system transactions can hardly be met. Blockchain，an emerging technical means， is suitable for distributed energy systems in solving the existing problems of new energy trading， due to the decentralization， tamper-proof and other technical characteristics of the technology. Based on this， a new energy transaction process based on blockchain technology is proposed. Business models are divided into three categories： smart energy integration， smart energy hosting and regional shared energy. Energy transaction services can be partitioned into three categories： operation and maintenance management service， system transformation service and market service. The evaluation index system for energy trading systems taking blockchain technology is constructed， and the trading system is analyzed by Analytic Hierarchy Process（AHP）-fuzzy comprehensive evaluation method. According to the results of the simulated case， the effectiveness of the evaluation index system for energy trading systems taking blockchain technology is proven.

Key words: new power system, blockchain technology, energy trading model, energy service business, evaluation index system, trading effect evaluation
