Abstract In recent years, rapidly increasing electric power demand and organizational concerns regarding social and environmental issues have resulted in significant attention being given to microgrids. However, sustainable microgrids that simultaneously address economic benefits and environmental and social issues have not been broadly explored by researches. This study addresses the sustainable microgrid design problem by leveraging blockchain technology to provide the real time-based demand response programs. Three sustainable objectives (economy, environment, and society) are formulated by a multi-objective mixed integer-linear programming model. A robust fuzzy multi-objective optimization approach is proposed to determine the optimal number, location, and capacity of renewable distributed generation units as well as the equilibrium supply and dynamic pricing decisions under uncertain demand, capacity, and economic, environmental, and social parameters. The proposed model and solution approach are then applied to a case study in Vietnam. We find that blockchain technology-based sustainable microgrid can result in a 1.68% and 2.61% increase of profitability and consumer satisfaction, respectively, and a 0.97% reduction of environmental impacts.

考虑区块链技术的可持续微电网设计用于基于实时价格的需求响应程序

摘要 近年来,快速增长的电力需求以及对社会和环境问题的组织关注导致对微电网的极大关注。然而,同时解决经济效益和环境和社会问题的可持续微电网尚未被研究广泛探索。本研究通过利用区块链技术提供基于实时的需求响应程序来解决可持续微电网设计问题。三个可持续目标(经济、环境和社会)由多目标混合整数线性规划模型制定。提出了一种鲁棒的模糊多目标优化方法来确定最优数量、位置、和可再生分布式发电机组的容量,以及在不确定的需求、容量和经济、环境和社会参数下的均衡供应和动态定价决策。然后将提出的模型和解决方案应用于越南的案例研究。我们发现基于区块链技术的可持续微电网可以分别使盈利能力和消费者满意度提高 1.68% 和 2.61%,并减少 0.97% 的环境影响。
