中文摘要:
      为满足港口日益增长的能源需求,改善港口地区环境污染问题,港口能源供应方式逐渐由传统燃油、煤电供能逐渐向涵盖冷、热、电、天然气在内的综合能源供能方式转变。港口岸电建设及设施电气化改造工程的持续推进,使得港口电能需求进一步增加。针对这一现状,提出了一种考虑综合需求响应的港口综合能源系统优化运行方法,通过分析系统内各设备间的能量转换耦合联系,构建了基于能源集线器的港口综合能源系统多能耦合转换模型,并根据港口可调负荷特性,建立了港口综合需求响应模型。在此基础上,综合考虑能源价格、环境污染、能量损耗等因素对系统运行的影响,以系统运行成本最低为目标,建立了考虑综合需求响应的港口综合能源系统运行优化模型。算例结果验证了该优化方法可有效降低港口综合能源系统的运行成本,减少港口用电高峰时段的电力负荷需求。
英文摘要:
      In order to meet the increasing energy demand of ports and decrease the environment pollution in port areas, the mode of port energy supply has gradually transformed from the traditional mode of oil and coal-fired power supply to integrated energy supply including cooling, heating, electric power and natural gas.The development of the shore-to-ship power supply system and infrastructure electrification has furtherly increased the demand for electricity. An optimal operation method of port integrated energy system(PIES)considering integrated demand response(IDR)is proposed. A multi-energy coupling conversion model of PIES based on energy hub is built by analyzing the coupling connection of energy conversion among equipment in PIES, and an IDR model of port is established based on the classification of port loads. On this basis,comprehensively considering the impact of energy prices, environment pollution, energy loss and other factors on the operation of PIES, an optimal operation model of PIES considering IDR is constructed. The proposed method is applied to a PIES, and the simulation results show that this method can effectively reduce the total operation cost of PIES and effectively reduce the peak demand of electric power load.
