In this context, the electricity transmission grid, in addition to its essential role in transporting energy to the distribution networks and enabling the connection of new renewable power capacity, plays a fundamental role in providing critical services for the security of supply (reliability, wave quality, response capacity when faced with excess energy generation and the control of voltage level and frequency), which become even more relevant in a more decentralized system and with new elements (digitization, distributed generation, self-consumption ...), requiring greater coordination between all agents.
