Mismatch between power production

Time variations in wind power are determined by passage of weather front systems. Typical passage of fronts over Denmark has a pattern exhibiting similar conditions over periods of a few days. This has implications for the amount of energy storage that would remove the mismatch between variable wind power production and demand. Lulls are followed by periods of high winds with delays of typically 3-6 days and very rarely over 12 days.
