Abstract Electricity generated from renewable sources, which has shown remarkable growth worldwide, can rarely provide immediate response to demand as these sources do not deliver a regular supply easily adjustable to consumption needs. Thus, the growth of this decentralized production means greater network load stability problems and requires a better grid connection all around Europe and energy storage as a crucial element in the management of energy from renewable sources, allowing energy to be released into the grid during peak hours when it is more valuable. Obviously there needs to be some way for energy suppliers to separate the processes of energy generation and consumption by storing energy until it is needed. For this project, I had to investigate and evaluate the use of an energy storage system to optimize the performance of future electric power systems dominated by renewable energy generators. The goal of this project is to separate the process of demand and production by storing energy. For that purpose, firstly, has been done a description of the current status of the electrical-grid system in Denmark and Spain. After has been done an estimation taking into account the forecasts of new renewable sources which are going to be installing (mainly wind farms) to figure out how much energy would be needed to store in 2020 in Spain for the properly work of the electrical system. Then, the different technologies for electrical storage which are nowadays available are described. For this Master Thesis, SMES has been chosen for storing electricity and a brief explanation of how it works, how this technology is nowadays and the expectative for the future has been carried out. Finally a study of heat transfer and an estimation of how much power would be needed for cooling this system to the cryogenic temperature have been carried out.
