Polygeneration is an energy process for the simultaneous production of multiple products (usually four or more and often including electricity, heat, cool, synthetic fuels, desalinated water). Applications for such systems are particularly prevalent in industry, communities and utilities. The benefits of polygeneration are numerous and noteworthy, including significant efficiency increases and emissions reductions, relative to stand-alone processes for the corresponding separate products.***Although simple generation systems for two or three products exist, advantageous polygeneration systems are not commonplace. Furthermore, those that do exist are usually not optimal. Thus they do not realize all of their potential benefits. This is in part due to there being a lack of innovative polygeneration systems as well as a lack of understanding of their most advantageous applications. The complexity of polygeneration systems and their operation makes essential research into all of these areas using appropriate methods and tools.***The proposed research aims to address these needs. The objectives are 1) to develop and optimize innovative and advanced polygeneration systems, focusing on environmentally benign and sustainable options; 2) to establish the optimal role for energy storage in polygeneration; and 3) to develop advantageous and innovative building and community energy systems via intelligent applications of polygeneration systems, with a focus on achieving extremely high efficiency buildings and communities. ***The approach utilized will involve detailed thermodynamic modelling and simulation, as well as creative system development activities. Advanced multi-objective.optimization will be employed, incorporating appropriate constraints. The research will exploit advanced methods such as exergy, exergoeconomic and exergoenvironmental analyses, in developing novel systems and their analysis and optimization. ***The proposed research will yield numerous benefits and be of great technical significance in the engineering of advanced energy systems and their application. In particular, the proposed research will lead to many innovative developments, and improved/optimal designs for polygeneration energy systems, energy storage and building and community energy systems. The research will allow for energy systems with enhanced efficiency, economic and environmental characteristics, and expanded economic growth and employment in this sector of Canada's economy.

多联产是一种同时生产多种产品（通常是四种或更多，通常包括电，热，冷，合成燃料，脱盐水）的能源过程。这种系统的应用在工业、社区和公用事业中特别普遍。多联产的好处很多，值得注意，包括相对于相应的单独产品的独立工艺而言，大大提高效率和减少排放。虽然存在用于两种或三种产品的简单发电系统，但有利的多联产系统并不常见。此外，那些确实存在的通常不是最佳的。因此，他们没有意识到所有潜在的好处。这部分是由于缺乏创新的多联产系统以及缺乏对其最有利应用的了解。多联产系统及其运作的复杂性使得必须使用适当的方法和工具对所有这些领域进行研究。拟议的研究旨在满足这些需求。其目标是：1）开发和优化创新和先进的多联产系统，重点是环境友好和可持续的选择; 2）建立能源储存在多联产中的最佳作用; 3）通过多联产系统的智能应用开发有利和创新的建筑和社区能源系统，重点是实现极高效率的建筑和社区。* 采用的方法将涉及详细的热力学建模和模拟，以及创造性的系统开发活动。将采用先进的多目标优化，并结合适当的约束。该研究将利用先进的方法，如火用，火用经济和火用环境分析，在开发新的系统，分析和优化。* 拟议的研究将产生许多好处，并在先进能源系统的工程及其应用方面具有重要的技术意义。特别是，拟议的研究将导致许多创新的发展，并改善/优化设计的多联产能源系统，能源储存和建筑和社区能源系统。这项研究将使能源系统具有更高的效率、经济和环境特性，并扩大加拿大经济这一部门的经济增长和就业。
