In microgrids, electricity production and consumption must be in balance at all times. Therefore, existing generation assets, like diesel generators, need to control voltage and frequency and provide spinning reserve capacity. This restricts their operation and they must be kept running even when sufficient renewable energy is available.
The adaptive flywheel takes over voltage control and frequency regulation and provides spinning reserve capacity at the same time. The microgrid can operate in diesel-off-mode. This results in great fuel savings as well as in a reduction of maintenance costs and CO2 emissions.
