研究成果
This document presents the focus of resilience for electrical systems. In general, resilience is understood as the capacity of a system to withstand high-impact and low-probability events such as natural disasters. Some authors propose evaluating resilience in each event, losing traceability in the evaluation of resilience over time. This can make the electrical grid vulnerable to future events, due to the low probability of occurrence. In this sense, the evolutionary evaluation of the resilience of electrical systems is proposed, specifically for low-voltage distribution networks. Additionally, the evaluation of resilience for networks with the integration of photovoltaic generation is proposed, as a distributed resource. This supposes the evaluation of resilience at the local coupling point (PoC), at the common coupling point (PCC), and in the distribution network; with this, the evolution of resilience every 1 minute could be observed, as is proposed.
