On the Influence of Renewable Energy Sources in Electricity Price Forecasting in the Iberian Market

Abstract

The mainstream of EU policies is heading towards the conversion of the nowadays electricity consumer into the future electricity prosumer (producer and consumer) in markets in which the production of electricity will be more local, renewable and economically efficient. One key component of a local short-term and medium-term planning tool to enable actors to efficiently interact in the electric pool markets is the ability to predict and decide on forecast prices. Given the progressively more important role of renewable production in local markets, we analyze the influence of renewable energy production on the electricity price in the Iberian market through historical records. The dependencies discovered in this analysis will serve to identify the forecasts to use as explanatory variables for an electricity price forecasting model based on recurrent neural networks. The results will show the wide impact of using forecasted renewable energy production in the price forecasting.

Forecasting day-ahead electricity prices: A review of state-of-the-art algorithms, best practices and an open-access benchmark

“…In 2019, the main focus of the papers was the same as in 2018: 1) evaluating the performance of different deep recurrent networks (mostly LSTMs) [16,30,45,47,[82][83][84], 2) proposing new hybrid deep learning methods usually based on LSTMs and CNNs [17,28,36,82,[85][86][87], or 3) employing regular DNN models [15,46,88]. Similarly, as with most studies in 2018, the new studies were more limited than [12,59] as no comparisons with state-of-the-art statistical methods were made and long test datasets were seldom used.…”

Hybrid Local General Regression Neural Network and Harmony Search Algorithm for Electricity Price Forecasting

“…The electric power market got considerable interest from research over the last few years [1]- [3]. Proposing accurate forecasting methods of the electricity price (EP) is very difficult due to the unique electric price features for instance highfrequency, non-linearity performance and seasonality, climatic variables, high volatility, a high percentage of unusual prices, plus the influence of renewable energy resources [4]- [6]. This makes the price forecasting procedure a challenging job for the researchers [7].…”

“…Renewable energy resources are the good choices for us. Wind and Solar Energy resources are the most popular resources [1][2][3][4]. Some countries have planned to use the renewable energy resources to replace the fossil fuels [5][6][7][8][9][10].…”
