Demand Response Strategy for Commercial Building Power Supply Conversion Entities Based on Alliance Chain Technology

Commercial buildings have abundant flexible resources and can effectively participate in demand response. However, widespread power supply conversion in commercial buildings can lead to insufficient enthusiasm for end users to participate in demand response. On the one hand the settlement information of demand response is not transparent and end users lack trust in the power supply conversion entities, on the other hand, the main power supply conversion entities have ignored the electricity utility of end users, and the incentive mechanism is unreasonable. To address above issues, by applying the alliance chain technology to the demand response of commercial building power supply conversion, this article constructs an alliance chain-based commercial building power supply conversion demand response system to achieve decentralized and reliable transfer of demand response. Based on the electricity consumption characteristics of public areas and end users in the context of power supply conversion, a demand response strategy is proposed with consideration of the power supply conversion characteristics of commercial buildings. The proposed alliance chain system was validated in a small commercial building environment in Nanjing, achieving transparent transaction and settlement functions of the alliance chain in the demand response process of commercial buildings. At the same time, simulation results show that the proposed strategy successfully reduces the electricity consumption cost of the power supply conversion entities by 33.6%, confirming the effectiveness of the proposed strategy.
