摘　　要：当前迫切需要研究实现可再生能源与电网统一协调发展的能源互联网系统提供技术支撑。通过提出扩展的能源枢纽模型,基于考虑了太阳能光伏发电和可再生能源发电储能技术的参与。分析日常负载需求(例如电、热和冷却)和使用时间能源价格来设置优化问题。为了优化总能源成本,构建了一个数学模型,其中包括一些约束,例如能源枢纽的输入输出能量平衡,电价,系统的容量限制以及可再生能源发电技术的储能效率。比较了基于不同能源枢纽结构的运营案例,以评估太阳能应用和电池储能系统、可再生能源发电技术对运营效率的影响。结果表明,所提出的模型预测了电力和天然气的所需量的重大变化,从而导致总成本降低。At present,there is an urgent need to provide technical support for the purpose of studying and achieving the energy internet system with unified coordination and development of renewable energy and power grid.Based on the extended energy hub model,the participation of energy storage technology for solar photo voltaic power generation and renewable energy generation is considered.The optimization issue is set through the analysis of daily load demand(e.g.,electricity,heat and cooling)and the use of time energy price.For optimizing the total energy cost,a mathematical model is constructed,which includes some of such constraints as the input and output energy balance of energy hub,electricity price,capacity limitation of system and energy storage efficiency of renewable energy generation technology.The operation cases based on different energy hub structures are compared to assess the influence of solar energy application,battery energy storage system and renewable energy generation technology on operation efficiency.It is shown by the result that the proposed model has predicted significant changes in the demand for electricity and natural gas,thereby resulting in lower total costs.
