Impact of the implementation of the new quarter-hourly model on a wind farm in the peninsular electricity system

Abstract

.

The electricity sector, in global terms, has undergone significant and severe structural changes, with the aim of allowing free choice for energy consumers and achieving greater competition between markets. In this regard, quarter-hourly deviations are promoted by European regulations for the purpose of energy market management. The EU requires electricity suppliers to provide data on their energy production and consumption every 15 minutes. This requirement has been designed to promote transparency and competition in the energy market. Until now, Spain has used an hourly deviation settlement system, so the implementation of this new model will entail a complex and gradual change. In fact, the introduction of a quarter hourly market would enable consumers to access more frequent pricing information, which would help them make more informed decisions about their energy usage. This would also create opportunities for more sophisticated demand-side management strategies, such as real-time pricing and automated demand response. Although the integration of the electrical sector is an important aspect of the EU's broader efforts to create a single energy market and reduce carbon emissions, there are still significant challenges to be overcome, such as the need to improve grid infrastructure, ensure the security of supply, and harmonize regulatory frameworks across member states. The main objective of this article is to study the impact that the implementation of the new quarter-hourly model will have in a wind farm, given the intrinsic variability of this energy source and the current reliability of prediction systems. With continued advancements in technology and improved forecasting techniques that allow suppliers to adjust their operations in real-time based on changing conditions, it is likely that the uncertainty of unmanageable units will continue to decrease over time, making them an even more reliable and efficient source of clean energy in the future.
