Probabilistic Load Forecasting Based on Adaptive Online Learning

چکیده
Load forecasting is crucial for multiple energy management tasks such as scheduling generation capacity, planning supply and demand, minimizing trade costs. Such relevance has increased even more in recent years due to the integration of renewable energies, electric cars, microgrids. Conventional load techniques obtain single-value forecasts by exploiting consumption patterns past demand. However, cannot assess intrinsic uncertainties capture dynamic changes patterns. To address these problems, this paper presents a method probabilistic based on adaptive online learning hidden Markov models. We propose with theoretical guarantees, experimentally their performance scenarios. In particular, we develop that update model parameters recursively, sequential prediction using most parameters. The evaluated datasets corresponding regions have different sizes display assorted time-varying results show proposed can significantly improve existing wide range

Abstract: In recent years due to problems such as population growth and as a result increase in demand for electrical energy, power systems have been faced with new challenges that not existed in the past. One of the most important issues in modern power systems is economic load dispatch, which is a complex optimization problem with a large number of variables and constraints. Due to the comple...
متن کاملAdaptive Learning of Smoothing Functions: Application to Electricity Load Forecasting
This paper proposes an efficient online learning algorithm to track the smoothing functions of Additive Models. The key idea is to combine the linear representation of Additive Models with a Recursive Least Squares (RLS) filter. In order to quickly track changes in the model and put more weight on recent data, the RLS filter uses a forgetting factor which exponentially weights down observations...
