本研究探讨不同操作策略对微型燃气涡轮机三联产系统（MGT-TGS）经济性与环保性的影响。MGT-TGS涵盖热带地区选定建筑物的电力、供暖和制冷负荷。所用的原动机是电力输出能力为30千瓦和65千瓦的MGT。研究了四种操作策略：功率匹配、热匹配、混合匹配和基本负载。计算了MGT整个生命周期的净现值和减排指数。研究发现，在无补贴电价下，MGT-TGS在25年寿命结束时只能产生正的净现值。混合匹配和功率匹配运行策略可以产生正的净现值，因为系统可以产生更多的电力。然而，这些操作策略不能减少排放物，特别是CO2和CO，当它们与CCGT（联合循环燃气涡轮机）相比时。基本负荷是唯一的运行策略，即使与CCGT相比，也可以减少所有排放。当使用CPERI（每排放减少成本指数）公平考虑经济和环境绩效时，混合匹配是最佳解决方案，因为它可以产生基于NPV的16.0 - 92，407美元的CPERI。
This study investigates the effect of employment of different operation strategies on the economic and environmental performance of a micro gas turbine trigeneration system (MGT-TGS). The MGT-TGS covers power, heating and cooling load of a selected building in a tropical region. The prime movers used were MGTs with electrical output capacity of 30 kW and 65 kW. Four operation strategies; Power-Match, Heat-Match, Mix-Match, and Base-Load were examined. The Net Present Value and Emissions Reduction Index throughout the life cycle of the MGTs were calculated. It was found that MGT-TGS can only generate positive NPV (Net Present Value) at the end of 25 years life time under unsubsidized electricity price. Mix-Match and Power-Match operation strategies can generate positive NPV because the systems can generate more electricity. However, these operation strategies cannot reduce emissions especially CO2and CO when they were compared to a CCGT (Combined Cycle Gas Turbine). Base-Load is the only operation strategy that can reduce all emissions even when it is compared to a CCGT. When the economic and environmental performance is fairly considered using CPERI (Cost Per Emissions Reduction Index), Mix-Match is the optimum solution because it can generate CPERI of US$16.0–92,407, based on NPV.
