Verification test result of isolated operation of a microgird configured with some new energy generators on Aichi EXPO. 2005 showed stable controllability without rotating machine. However, improvement of voltage fluctuation with changing reactive power of loads had been hoped. Some improvements of system voltage control had been implemented on the maicrogrid moved to Central Japan Airport City. This paper presents a verification test result of the improvement of voltage fluctuation in isolated operation with PAFC output power compensation control by NaS batteries and also presents a simulation study of a further improvement of voltage control strategies of PAFC inverters.
