要約(英語): A large blackout in 2006 because of two-circuit failure on 275kV transmission line will be well remembered. One of successful methods against such blackout is to maintain the islanded system stable. However, the stability is doubtful when renewable energy highly penetrates and as the result much amount of synchronous generator stops. There are two issues. One is frequency deviation due to demand-supply imbalance. Another is instability due to shortage of voltage support capability of the islanded system. The phenomenon is fast and therefore serious, if it can be exists. As the third issue of islanded system, frequency instability of hydro islanded system. However, it will be quite rare to appear a large islanded system only by hydro power. Usually oscillatory instability, in which small generator's rotor angle swing gradually grows, appears in loosely interconnected large system, which is divided into two groups, but is not remarkable in tightly interconnected local islanded system. However, another oscillatory instability can exists. The paper theoretically clarifies the phenomenon; identifies dominant factors of the phenomenon; verifies the theory by simulation; and make a caution for preparing high renewable energy integration.
