19th International Conference on Renewable Energies and Power Quality , Almería (España). 28 julio 2021
Decarbonization of the economy to fulfill the Paris agreement goals requires the development of huge amounts of renewable power generation. Wind and solar photovoltaic power generation technologies have become technically mature and economically competitive technologies. Wind and solar photovoltaic generation are connected to the grid through power electronic converters. It results in formidable challenges for power system stability, control and protection. Due to such fact, it can be stated that ac power systems are facing the largest transformation since Edison, Tesla and Westinghouse.
The development of wind and solar photovoltaic generation depends critically on the access to the grid. In contrast to synchronous generation, the access to the grid of converter based generation (also called non-synchronous generation) is affected by a number of technical constraints.
The Spanish regulation of the grid access of non-synchronous generation has been recently reformulated.
This contribution will review the new regulation . The former regulation will be also discussed (, ). The former regulation was based exclusively on the Short Circuit Ratio criterion . The new regulation is based on the Weigthed Short Circuit criterion  together with steady-state and dynamic security assessments.
