Recently, there has been growing interest in utilizing dispersed generation systems, which are grouped into micro turbine systems, co-generation systems, etc., as a substitute for fuel oil energy and a technology to prevent a global warming. Since start-up time of dispersed generation systems is short, it is possible to operate systems to supply load power corresponding to a demand. Moreover, PPS (Power Producer and Supplier) can participate in power retail sales company, since deregulation of electric utilities has been started from 2000. However, PPS have to keep instantaneous generating power commissioning rule, to maintain supply and demand balance between customer and supplier. Therefore, in this paper, we examine instantaneous generating power commissioning for dispersed generators that start-up time is short and is possible to operate systems to supply power load corresponding to a demand. We adopt a PI controller as a controller. The system is composed of double control loop in inner loop and in outer loop. In inner loop electric power are controlled and in outer loop electric energy are controlled. The controller parameters are designed with using the pole-placement technique. The effectiveness of the proposed control system is confirmed by simulations.
