To utilize photovoltaic power generation (PV), the compensation for power fluctuation is necessary since the fluctuation has a bad influence on electric power system. Therefore, micro grid using several kinds of decentralized generation plants is considered to be a good solution. In this paper, the feasibility of gas engines to compensate for the PV fluctuation is investigated from the viewpoint of exhaust gas NOx, and power generation cost by simulation. As for NOx, the amount of NOx increases as the output of a gas engine fluctuates, but this increase on NOx hardly has a problem in micro grid. As for power cost, it can be decreased by combining battery and a few kinds of gas engines. As a result, gas engines can be used in micro grid as decentralized generation plants.
