Abstract

To realize stable operation of microgrids, gas engines require to compensate load changes from demands and variation of other renewable energy devices. Then, prehension of load following capability is important in gas engines. In addition, when biomass gas is supplied to gas engines, effect of fuel component variation on dynamic characteristics must be investigated, because components of biomass gas depend on operating condition of gasification or raw material. This study proposed a dynamic simulation model of gas engine and estimated transient response to load changes. Load changes were sinusoidal wave, and bias value, amplitude and frequency of them were varied. As a result, the frequency has more influence on transient response than the bias value and the amplitude. When biomass gas is supplied to gas engines, transient response is worce than city gas over the frequency of 0.1 Hz.
