Resumen
Moving towards low-carbon electricity systems through the massive deployment of
renewable energy sources (RES) presents a unique opportunity to combat climate change, but it also poses
enormous technical challenges, especially from a frequency viewpoint. To ensure a secure RES integration
in terms of frequency stability, system operators worldwide have adopted new grid codes requiring RES to
provide fast frequency response (FFR). However, if not properly justified, stringent requirements may pose
an unnecessary barrier to further RES development and slow their network integration. In this context, this
paper presents a methodological framework for systematically defining FFR requirements for RES to
ensure system frequency stability. The proposal comprises: i) a model for simulating the dynamic response
of system frequency following a contingency with reduced computational effort, ii) a model for reallocating
contingency reserves with economic criteria to avoid loss of load following a contingency, and iii) novel
indices for characterizing the dynamic performance of system frequency in terms of key operational
characteristics, which are then used for defining frequency related grid codes. The benefits and
practicability of our proposal are demonstrated in a case study on the Northern Interconnected System in
Chile. We show how our proposal can be used to i) identify system operating conditions in which the
contribution of RES with FFR is necessary to avoid loss of load and ii) to propose a technically and
economically justified grid code that allows both to foster further RES integration while ensuring power
system security.
