Blockchain-based Smart Contract Enabling Electric Heating Load Participate in Demand Response

As a good demand-response resource with time-shifting characteristics, electric heating load (EHL) is an important means to consume renewable energy. A large number of electric heat users need an efficient and secure platform to participate in market transactions, blockchain technology is introduced to solve the mentioned issue. This paper proposes a demand response contract supported by blockchain technology for market-oriented operations involving electric heating users. First, this paper establishes a demand response model for electric heat load. Secondly, the method of day-ahead contract for electric heating load trading is proposed, it updates the response planning function according to the price, and stores the day-ahead trading results in the blockchain bill. In the real-time contract, the results are recorded to the bill according to consensus for possible power deviations, and provides a means of settlement. Finally, the calculation example verifies the validity of the proposed smart contract.
