Study on the dynamic performance of a microtubine based microgrid

As a kind of clean and high efficiency technology, micro turbine has a broad application prospect in China. Combining the micro turbine with local load to form micro grid could realize high efficient of energy and high reliability of power supply. With the rapid development of the smart grid concept and micro grid technology, distributed generation based on micro turbine play a more and more important role. Base on the national 863 goal-oriented project “The key technology and demonstration project of grid-connecting issue for a MW level CCP distributed energy MicroGrid”, this paper investigate the dynamic performance of a micro grid based on capstone C200 micro turbine. The structure of the micro grid and general control principle of the turbine is studied first. After that, several tests including start, stop, load swing, mode transition and so on are conducted. to study the dynamic response of the voltage and frequency of the micro grid in both grid connect and stand alone mode. The tests result could be used to further evaluate the dynamic behavior of micro grid and validate models for simulation studies.
