本文介绍了中国现有能源系统整合风电的能力，并探讨了中国能源系统需要如何做好准备，以便在未来整合更多波动的可再生能源。基于这一目的，本文利用EnergyMonitoring建立了2007年中国能源系统的模型，并利用该模型对三个问题进行了研究。首先，模型本身的准确性已被检查，然后在现有的能源系统中的最大可行的风电穿透已被确定。最后，对中国能源系统未来大规模整合可再生能源的障碍进行了讨论，并提出了建议。结果表明，利用EnergyData构建的模型能够较准确地模拟中国的能源系统。根据目前确保电网稳定性的法规，从技术和经济角度来看，中国现有能源系统中最大可行风电渗透率约为26%。由于其刚性的供电结构和确保电网稳定性的任务主要留给大型燃煤发电厂，当增加系统中的风力发电渗透时，燃料效率下降。从长远来看，中国能源系统至少有三种可能的解决方案来整合大规模波动的可再生能源：重新设计法规，通过多样化的参与者来确保电网稳定性，例如包括水电和热电联产工厂;整合大型热泵与蓄热设备，以满足区域供热需求，并发展电动汽车，以促进非高峰用电。(C)2011爱思唯尔有限公司版权所有。
This paper presents the ability of the existing Chinese energy system to integrate wind power and explores how the Chinese energy system needs to prepare itself in order to integrate more fluctuating renewable energy in the future. With this purpose in mind, a model of the Chinese energy system has been constructed by using EnergyPLAN based on the year 2007, which has then been used for investigating three issues. Firstly, the accuracy of the model itself has been examined and then the maximum feasible wind power penetration in the existing energy system has been identified. Finally, barriers have been discussed and suggestions proposed for the Chinese energy system to integrate large-scale renewable energy in the future. It is concluded that the model constructed by the use of EnergyPLAN can accurately simulate the Chinese energy system. Based on current regulations to secure grid stability, the maximum feasible wind power penetration in the existing Chinese energy system is approximately 26% from both technical and economic points of view. A fuel efficiency decrease occurred when increasing wind power penetration in the system, due to its rigid power supply structure and the task of securing grid stability, was left primarily to large coal-fired power plants. There are at least three possible solutions for the Chinese energy system to integrate large-scale fluctuating renewable energy in the long term: Redesigning the regulations to secure grid stability by means of diversifying the participants, such as including hydropower and CHP plants: integrating large-scale heat pumps combined with heat storage devices to satisfy district heat demands and developing electric vehicles to promote off peak electricity utilisation.
