Blockchain based smart contract for bidding system

Abstract: Because of the popularity of the Internet, the integration services have gradually changed people daily life, such as e-commerce activities on transactions, transportation and so on. The E-auction, one of the popular e-commerce activities, allows bidders to directly bid the products over the Internet. As for sealed bid, the extra transaction cost is required for the intermediaries because the third-party is the important role between the buyers and the sellers help to trade both during the auction. In addition, it never guarantees whether the third-party is trust. To resolve the problems, the blockchain technology with low transaction cost is used to develop the smart contract of public bid and sealed bid. The smart contract, proposed in 1990 and implements via Ethereum platform, can ensure the bill secure, private, non-reputability and inalterability owing to all the transactions are recorded in the same but decentralized ledgers. The smart contract is composed of the address of Auctioneer, the start auction time, deadline, the address of current winner, the current highest price. In the experiments, the accounts are created through Ethereum wallet. In miner stage, the MinerGate is used in miner stage for obtaining money to pay the transaction fee. At recorder stage, the nodes of blockchain are synchronized to generate smart contract.

Residential Appliances Direct Load Control in Real-Time Using Cooperative Game

Abstract: The relatively fixed residential day-ahead real-time electricity price reflects insufficient information of the market, so the response of residential energy management system (EMS) to the real-time pricing (RTP) is not complete and therefore retailers are exposed to the risk of price fluctuation in balance market. Direct load control (DLC) in cooperative game is proposed in this paper. A cooperative game union comprised of some users and a retailer is established to minimize the union costs. The union provides an opportunity to access the balance market indirectly for residents and to reduce risks and costs for the retailer. In addition, Shapley value which embodies the fairness is used in union profits allocation. The method that avoids bidding for residential users simplifies the thresholds of residents to participate in market. Furthermore, the DLC union contributes to imbalance self-management for the retailer, which helps him avoid paying for the regulation cost involved in the deviation between the total quantity bought at markets and the actual consumption. The achievement of union’s goal respects the constraints set by users. The method that alleviates the disturbance of DLC to residents meets the dual goals of being both fully responsive and non-disruptive.
