Book Title: Chapter 4 – Microturbine Generation Power Systems

Recently, the trend toward highly efficient and less-polluting DGs is increasing due to efforts to reduce environmental pollution and overall costs. The microturbine generation (MTG) system is a fast-growing and most promising DG source which holds some of the answers to the efficiency, pollution, and management issues that the utility industry faces. The MTG's potential merits, along with very short start-up time and high reliability, lead to its use as an individual or hybrid power source. The MTG can be used in transportation systems, remote power and emergency power systems, and in combination with other DGs. https://doi.org/10.1016/B978-0-12-804208-3.00004-2 In this chapter, the author presents an overview of the MTG, beginning with a brief history of the invention and production of the MTG, then extensive statistical information about its growth and expansion. The statistical information indicates greater use of the MTG in the future for various applications. The microturbines are subsets of gas turbines with a similar thermodynamic cycle, so the author offers a brief description of gas turbine configuration and the Brayton thermodynamic cycle. Explanation of the MTG components and applications is provided, along with discussion of how to connect components and determine which interface converters are required, based on the MTG type. MTGs with power electronic interfaces are described in detail. The author comprehensively describes the effect of temperature or altitude on microturbine operation, as well as the MTG pollutant emissions, completing the MTG analysis. Detailed dynamic modeling of the MTG system is presented because its performance studies are necessary to deal with issues in system management and interconnection operation. The MTG can operate in stand-alone mode or grid-connected mode. The author describes control strategy in these modes, and simulations are carried out in a PSCAD/EMTDC environment. Simulation results show fast dynamic response and efficient performance of the MTG as an individual power or grid supporter source. https://doi.org/10.1016/B978-0-12-804208-3.00004-2
