Most of the time one set is running but as the wind drops off other sets will start up through standard power management. This has allowed the wind energy penetration to be as high as 70% without any energy storage system, particularly at night and at weekends when the load is very steady.
“ComAp’s Hybrid control system allows the island of Vanuatu to combine wind turbines with diesel/coconut oil powered generators, allowing significant cost savings. Thanks to ComAp’s control solution the wind turbines can supply up to 70% of the island electricity demand without any need for energy storage.”
