Trusted low-carbon optimized economic dispatch for integrated energy industrial park based on blockchain technology

This paper focuses on the low-carbon trustworthy economic dispatch strategy of integrated energy industrial parks that merge integrated energy systems with high-carbon production enterprises. A ladder-type carbon trading mechanism is proposed with a particular emphasis on environmental protection and carbon reduction, which incorporates the carbon trading cost into the total dispatching cost and could incentivize the industrial park to operate in a low-carbon manner. A trustworthy data attestation and traceability framework based on blockchain technology is developed to ensure the trustworthiness of device and enterprise production, operation, and transaction data within the park, and to provide data query and traceability functions. Furthermore, the on-chain and off-chain storage mechanisms and the internal and external dual-chain collaboration mechanisms are conducted to alleviate data management and storage pressures, isolate sensitive data, and satisfy differentiated data management needs. The simulation result demonstrates that applying the ladder-type carbon trading mechanism can effectively reduce the carbon emissions of industrial parks, and the proposed framework can be beneficial to accurate load forecasting and practical dispatch strategies.
