Abstract Renewable energy is a promising solution for addressing social and environmental issues related to the rapidly rising electric power consumption of manufacturers. Recently, a number of policies have been proposed by governments to stimulate the use of renewable energy by manufacturers. Financial incentives are considered as an efficient lever to increase the penetration of renewable energy. This study solves a blockchain-based renewable energy microgrid design problem, where the bank finances a loan to the power company to establish renewable generation units and the power company also offers a credit period for manufacturers to stimulate demand. Blockchain technology can be applied to mitigate default risk. The objective is to determine the number and location of renewable generation units, energy price in the time-of-use scheme, credit time to manufacturers, and blockchain implementation effort while maximizing the expected network profit. A solution method based on robust type-2 fuzzy programming was developed to solve the described problem. The application of the proposed approach was examined using an empirical case study. The results show that uncertain demand and default risk have a strong effect on the solution, and the total profit of the renewable energy microgrid is improved by approximately 1.73% using the proposed approach.

考虑违约风险和需求不确定性的基于区块链的可再生能源微电网设计

摘要 可再生能源是解决与制造商快速增长的电力消耗相关的社会和环境问题的有前途的解决方案。近期,各国政府出台多项政策,鼓励制造商使用可再生能源。财政激励措施被认为是提高可再生能源渗透率的有效杠杆。本研究解决了基于区块链的可再生能源微电网设计问题,即银行为电力公司提供贷款以建立可再生发电机组,电力公司还为制造商提供信贷期以刺激需求。区块链技术可用于降低违约风险。目标是确定可再生发电机组的数量和位置、使用时间计划中的能源价格、对制造商的信贷时间,以及区块链实施工作,同时最大化预期的网络利润。开发了一种基于鲁棒 2 类模糊规划的求解方法来解决所描述的问题。使用实证案例研究检查了所提出方法的应用。结果表明,不确定性需求和违约风险对解决方案有很强的影响,使用所提出的方法,可再生能源微电网的总利润提高了约1.73%。
