A verification test result of islanding operation of a microgrid configured with new energy generators and a study of improvement of voltage control

Verification test results of the isolated operation of a microgrid configured with some new energy generators at Aichi EXPO 2005 showed stable controllability without a rotating machine. However, improvement of voltage fluctuation with changing reactive power of loads had been hoped for. Some improv...

Zusammenfassung:	Verification test results of the isolated operation of a microgrid configured with some new energy generators at Aichi EXPO 2005 showed stable controllability without a rotating machine. However, improvement of voltage fluctuation with changing reactive power of loads had been hoped for. Some improvements of system voltage control had been implemented on the microgrid moved to Central Japan Airport City. This paper presents the results of verification testing 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 further improvement of the voltage control strategies of PAFC inverters. © 2011 Wiley Periodicals, Inc.
