In order to increase the capacity of renewable energy in power systems, it is necessary to reduce power fluctuations. In this paper, the potential of gas engines (GEs) is evaluated by means of dynamic simulation. In this system, a hybrid generation system made up from GEs and photovoltaic cells (PV) supplies power to a large grid. Such a system is hoped. As a result of simulations, 9.9 kW GE is very useful to compensate PV power fluctuation. The efficient way using GEs to compensate scaled-up version of renewable energy is also discussed in this paper. In conclusion, the next three points are revealed to be effective. (1) Adding a larger scale GE to small scale GEs, (2) controlling preferentially the GE whose output variation speed is faster, and (3) decreasing lower limit of GE outputs.
