Numerical Modeling of Energy Systems Based on Micro Gas Turbine: A Review

In the context of the great research pulse on clean energy transition, distributed energy systems have a key role, especially in the case of integration of both renewable and traditional energy sources. The stable interest in small-scale gas turbines can further increase owing to their flexibility in both operation and fuel supply. Since their not-excellent electrical efficiency, research activities on micro gas turbine (MGT) are focused on the performance improvements that are achievable in several ways, like modifying the Brayton cycle, integrating two or more plants, using cleaner fuels. Hence, during the last decades, the growing interest in MGT-based energy systems encouraged the development of many numerical approaches aimed to provide a reliable and effective prediction of the energy systems' behavior. Indeed, numerical modeling can help to individuate potentialities and issues of each enhanced layout or hybrid energy system, and this review aims to discuss the various layout solutions proposed by researchers, with particular attention to recent publications, highlighting the adopted modeling approaches and methods.

Automated summary

Distributed energy systems play a key role in the transition to clean energy, especially when integrating renewable and traditional sources. Research on micro gas turbines focuses on improving their efficiency through modifications to the Brayton cycle, integrating multiple plants, and using cleaner fuels. Numerical modeling helps identify the potential and challenges of different layout solutions for these energy systems.
