Small and medium-sized power users are potential demand response resources with small single load capacity but large amount and strong power flexibility. A demand response system solution based on blockchain technology is designed

innovating the operation mode of demand response aggregator

and providing a feasible path for small and medium-sized users to participatein demand response events

so as to promote the development of demand response enterprise in the future. The scheme uses the block-chain technology to realize the depository and settlement services of demand response transaction data

to ensure that the demand response transaction data between aggregators and users cannot be tampered with

and the transaction process can be tracked

so as to improve the efficiency and credibility of evaluation and settlement.
