The electric power systems are in a transition to forms of generation that achieve cleaner production. In this regard, a new multi-objective model that helps with the problem of cleaner production investments is presented. The model can obtain convenient solutions where actors with opposed interests are participating. The novelty is the model considers more points of view than the classical approaches of the literature, which only consider a maximum of two actors involved in this field (the new model considers investment costs, greenhouse emissions, and operating costs). Another key contribution is that the real procedures of the generation and transmission stages and the dependences between electrical-natural gas systems are carefully represented and included in the model. It allows obtaining solutions in concordance with the real conditions. The model is applied to the energy system of Argentina by using an epsilon-constraint approach and Mixed Integer Linear Programming formulations. The test system supplies electricity to over 40 million people and neighboring countries. Besides, there is interdependency with the Argentinean Natural Gas system that operates in one of the most extended territories in Latin America. Results indicate that the solutions that are more convenient for all actors represent a mix between renewables and non-renewables technologies. Consequently, this proposal is differentiated from other ones that only consider the expansion concerning renewables technologies. The study reveals decreases in emissions up to 39% and the reduction in production costs up to 12% in comparison with the solution without investments.

用于分析实现电力清洁生产的投资的多目标模型。阿根廷制度的案例

电力系统正在向实现清洁生产的发电形式过渡。在这方面，提出了一种有助于解决清洁生产投资问题的新的多目标模型。该模型可以在利益相反的参与者参与的情况下获得方便的解决方案。新颖之处在于，该模型比文献的经典方法考虑了更多的观点，文献的经典方法最多只考虑了该领域涉及的两个参与者（新模型考虑了投资成本、温室气体排放和运营成本）。另一个关键贡献是发电和输电阶段的真实过程以及电力-天然气系统之间的依赖关系被仔细地表示并包含在模型中。它允许根据实际情况获得解决方案。该模型通过使用 epsilon 约束方法和混合整数线性规划公式应用于阿根廷的能源系统。该测试系统为超过 4000 万人和邻国供电。此外，与在拉丁美洲最广泛的地区之一运营的阿根廷天然气系统存在相互依赖关系。结果表明，对所有参与者都更方便的解决方案代表了可再生能源和不可再生能源技术的混合。因此，该提案与其他仅考虑扩展可再生能源技术的提案有所不同。研究表明，与没有投资的解决方案相比，排放量减少了 39%，生产成本降低了 12%。
