Abstract
To realize stable operation of micro grid, it is necessary for gas engines to compensate the load changes due to demand variation as well as the power provided by other renewable energy device. It is important to grasp the load following capability of gas engines because gas engines can be controlled in response to the demands. In addition, because of the variability of component of biomass gas which depending on the operating condition of gasification or raw material in case of supplying biomass gas to gas engine, dynamic characteristics against the fuel component variation must be investigated. In this study, newly developed dynamic simulation model of turbocharged gas engine is proposed and used to simulate transient operation. The constructed simulation model consists of Discrete Event Turbocharged Model (DETM) and Mean Value Turbocharged Model (MVTM). DETM calculates completely combustion state in gas engines and MVTM calculates the transient response of gas engines in a short time. The comparison calculated result with experiment result indicates the utility of constructed model. As a result, the combination DETM and MVTM can calculate the transient response of turbocharged gas engine sufficiently in a short time.
