Harvested from ORCID Public Data FileKoivisto, Matti in OpenAIREAbstract The effect of wind power on the electric power system is becoming increasingly important as more wind power is installed. This paper presents a Vector-Autoregressive-To-Anything (VARTA) process with a time-dependent intercept to model wind speeds in multiple locations. The model considers both temporal and spatial dependency structures in detail. It can be used in Monte Carlo simulations to assess the risk of very high or low wind speeds occurring in multiple locations at the same time and during consecutive hours. The long term simulation and short term forecasting results are assessed using measurements from 21 locations in Finland. A discussion on the applicability of the presented wind speed simulation method for the risk assessment of power systems is given.
