摘要
综合能源系统是多输入多输出系统,包含多种能源的输入、转换和储存等设备。我国西南地区拥有丰富可再生能源,适合建设多能互补的综合能源系统。文章考虑西南地区的能源结构,针对运行设备效率随环境和出力变化的特点,建立设备的全工况能量转换模型。以系统的年投资运行成本为目标,建立了集电气热冷能于一体的西南地区综合能源系统优化配置模型,并对模型进行分段线性化处理,降低模型的非线性度。最后通过算例分析,得出了西南地区用户侧综合能源系统在全工况用能场景下的最优配置,提高了经济和环保双重效益。
Integrated energy system is one of the important applications of Energy Internet.The integrated energy system is a multi-input and multi-output system,including input,conversion and storage equipment for multiple energy sources.Southwest China is rich in water energy and natural gas resources,as well as renewable energy such as wind energy and solar energy,which is suitable for the research and construction of integrated energy system with complementary multi energy.Firstly,based on the characteristics of energy structure in Southwest China,the energy conversion model of equipment under all operating condition is established according to the characteristics of operating equipment efficiency varying with environment and output.Then,an optimal configuration model of integrated energy system in Southwest China which contains electric heating and cooling energy is established with an aim of annual investment and operation cost.In order to reduce nonlinearity,the modal is performed with piecewise linearization.Finally,the optimal configuration of the integrated energy system on the user side is obtained through the analysis of cases.The result shows that the proposed configuration scheme is reasonable and achieves the dual benefits of economy and environmental protection of the integrated energy system.
