Parameter-free resolution of the superposition of stochastic signals
Teresa Scholz, Frank Raischel, Vitor V. Lopes +4
This paper presents a direct method to obtain the deterministic and stochastic contribution of the sum of two independent sets of stochastic processes, one of which is composed by…
Principal wind turbines for a conditional portfolio approach to wind farms
Vitor V. Lopes, Teresa Scholz, Frank Raischel +1
We introduce a measure for estimating the best risk-return relation of power production in wind farms within a given time-lag, conditioned to the velocity field. The velocity field…
Modeling and analysis of cyclic inhomogeneous Markov processes: a wind turbine case study
Teresa Scholz, Vitor V. Lopes, Pedro Lind +1
A method is proposed to reconstruct a cyclic time-inhomogeneous Markov pro- cess from measured data. First, a time-inhomogeneous Markov model is fit to the data, taken here from me…
A cyclic time-dependent Markov process to model daily patterns in wind turbine power production
Teresa Scholz, Vitor V. Lopes, Ana Estanqueiro
Wind energy is becoming a top contributor to the renewable energy mix, which raises potential reliability issues for the grid due to the fluctuating nature of its source. To achiev…
Uncovering wind turbine properties through two-dimensional stochastic modeling of wind dynamics
Frank Raischel, Teresa Scholz, Vitor V. Lopes +1
Using a method for stochastic data analysis, borrowed from statistical physics, we analyze synthetic data from a Markov chain model that reproduces measurements of wind speed and p…
