摘要
园区级综合能源系统中,燃气三联供和热泵在供冷(热)时均可优先选用,确定二者最佳的匹配容量是综合能源系统规划设计的重点之一。文中提出了一种通过解析法确定燃气三联供和热泵最佳匹配容量的方法。该方法基于各类设备单位装机容量在考察期内净现值的计算式,结合各负荷区间出现的频数统计,得到不同容量匹配方案下燃气三联供和热泵设备的年等效满负荷运行时数及相应的收益,通过比较考察期内系统总的净现值确定最优容量匹配方案。结合案例对本文所提出的分析方法进行了验证,指出推导分析法的优势在于可将最优结果产生的过程呈现,便于各参与方相机决策。
The capacity matching optimization of various heating and cooling sources,such as the combined cooling,heating and power-heat pump（CCHP-HP）system,is one of the important tasks for planning and designing the integrated energy system.This paper proposes an analytical method which can identify the optimized matching capacity of CCHP-HP system.The method is based on the formulation of net present value（NPV）of unit installed capacity within different scenarios.Combined with the frequency statistics of each load internal,the equivalent full load service hours of CCHP-HP and the corresponding income are acquired under different capacity matching schemes.The optimal scheme of CCHP-HP can be acquired from the comparison of total NPV value.Combined with a case study,the advantages of the proposed method are illustrated and it is convenient for the participants to make appropriate decisions.
