Abstract
In future power grids, a large integration of renewable energy sources is foreseen, which will impose serious technical challenges to system operators. To mitigate some of the problems that renewable energy sources may bring, new voltage and frequency control strategies must be developed. Given the expected evolution of technologies and information systems, these new strategies will benefit from increasing system observability and resources controllability, enabling a more efficient grid operation. The ELECTRA IRP project addressed the new challenges that future power systems will face and developed new grid management and control functionalities to overcome the identified problems. This work, implemented in the framework of ELECTRA, presents an innovative functionality for the control room of the cell operator and its application in assistance with the voltage control designed for the Web-of-Cells. The voltage control method developed uses a proactive mode to calculate the set-points to be sent to the flexible resources, each minute, for a following 15-min period. This way, the voltage control method developed is able to mitigate voltage problems that may occur, while, at the same time, contributes to reduce the energy losses. To enable a straightforward utilization of this functionality, a user interface was created for system operators so they can observe the network state and control resources in a forthright manner accordingly.

Summary
The European Union and other countries around the world, concerned with environmental problems, have set a target to decrease greenhouse gas emissions by 20%, compared to the values from 1990, as a main goal for 2020 [1]. The main problems are essentially related with the high unpredictability of this type of resources (wind and solar), which will demand new strategies for real-time energy balancing and voltage control [4]. These new approaches will strongly rely on information and communication technologies, which will be essential for control room operators. The ELECTRA IRP project, financed by the European Commission under the FP7 program, has as main goals to design the future grid architectures that will undergo beyond 2035 and to develop new functionalities for voltage and frequency control to mitigate problems that will arise with the foreseen changes [7].
