In these decades, various types of gas co-generation system have been developed and introduced into several sites such as hospitals, hotels, commercial buildings, district heating & cooling center, factories etc.to realize energy saving and reduce greenhouse gases. Typical to integrate a co-generation system are gas engine, gas turbine and fuel cell, and the recent trend of development for such components is high efficiency large scale model or distributed small scale model. In addition to obtain high-efficient power by interconnected operation, an emergency power could be supplied by islanding operation that is the most distinctive ability to keep social infrastructure from disasters. On the contrary high-efficient types of co-generation are not suitable to be operated by islanding operation because of its stability at load changes. In this paper we describe the high efficient gas engine co-generation combined with power storage divices to establish the stability at islanding operation and uninterrupted emergency power supply to the critical loads. And we show the design of cooperative control between two power sources to derive better performance of the integration.
