中文摘要：

能源系统是二氧化碳的主要排放源,因而能源的规划必须考虑CO2排放量的限制。本文采用图形方法合成了受碳排放限制的能源规划问题的总组合曲线,求得最小零碳能源目标,同时提出了与总组合曲线对应的组合表格算法,并将该图形和表格方法推广到多种清洁能源问题中。该方法不含迭代、试差步骤,在求解多种清洁能源问题时,可一步求得所有清洁能源的目标,比以往的方法更为简捷。爱尔兰电力部门的实例分析证明了该方法的有效性。

英文摘要：

In responding to the Kyoto Protocol, energy planning for greenhouse gas emissions reduction is crucial at both national and regional levels. This paper presents a new application of pinch analysis. A scenario is assumed wherein energy sector planning takes place with carbon emission constraints arising from an effort to reduce climate change effects. This work presents a graphical optimization method for energy sector planning with carbon emission constraints. A grand composite curve was constructed to determine the zero-carbon energy source line with minimum quantity. Meanwhile, the proposed approach can be accurately represented by the composite table algorithm and the targeting for the multi-source case can be obtained directly.
