Spanish case study on transmission grid expansion fostering large-scale RES-Electricity and storage integration

C. Fernandes , P. Frías , L. Olmos , A. Malpica

The major goal of the GridTech project is to conduct a fully integrated impact assessment of the implementation of innovative transmission network, bulk storage, and demand?side technologies into the European electricity system in order to exploit the full potential of RES generation across Europe, with lowest possible total electricity system cost. The time frame of GridTech analyses is up to the year 2050, with a particular focus on the target years 2020, 2030 and 2050. Under the project framework, regional analyses focusing on grid RES integration issues to be dealt with in seven target countries – Ireland, the Netherlands, Germany, Spain, Italy, Austria and Bulgaria – within different time horizons were carried out: (i) in the short?term (from 5 to 10 years time horizon), analyses are focused on technologies that optimize the use of the existing transmission network and on the effects of these technologies on power system operation and integration of RES generation; (ii) in the long?term (target years 2030 and 2050), analyses are focused on innovative technologies implemented to integrate larger shares of RES generation. The Spanish case study analyses comprise the assessment of different technologies in terms of their impact on system operation costs. I.e. the analyses focus on the comparison of power system operation with and without the studied technology for each time?horizon and the benefits computed are related to system operation cost savings. The 2020 study focuses on the installation of FACTS devices in the Southern Spanish transmission network to facilitate the integration of RES power coming from Morocco, assuming a significant deployment of RES generation in North Africa by 2020. Since the analysis is focused on the installation of a single FACTS device to avoid local grid constraints in the network area close to the interconnection with Morocco, it is assumed that power flows in the remaining interconnections are not affected by the use of this device.
