The energy system in Ireland is transitioning away from traditional dependable fossil fuels and relying more on the intermittent energy from renewable sources, mainly in the form of wind energy. A persistent period of low power generation is especially challenging when electricity demand is high. It’s important to quantify the duration and frequency of low-power-events so that the energy system can be managed in order to meet consumer’s electricity demand. This talk will present a brief analysis of low-wind-power events in Ireland. I will also describe a virtual wind farm network designed to represent current and future power generation potential.
