GRID RESILIENCE 2016 - Security and vulnerabilities of the electrical system

The paper proposes a fast algorithm to quantify the benefits brought by advanced control, protection and defense systems in increasing the penetration of renewable energy sources in weakly connected electric systems. The algorithm has been tested on a 2020 scenario in Sardinian power system.

The integration of non-dispatchable renewable energy sources (RES) poses serious challenges to power system planning and operation. At system level, a major issue regards the short and long-term frequency stability due to the reduction of regulating reserve margins, in turn brought about by the displacement of conventional generation and lack of contribution by the RES.

This problem is especially present in isolated or weakly connected systems, and may become the limiting factor for renewable penetration. The paper proposes a fast algorithm to quantify the benefits of advanced control, protection and defense systems in increasing RES penetration in weakly connected power systems. In fact evaluating the impact of these advanced systems may be of paramount importance at a generation planning stage. The algorithm is tested on a 2020 scenario of the Sardinian power system and I is cross-validated against a time domain simulator.
