This paper aims to review the literature related to defense schemes to conduct a defense scheme design process in order to maintain the stability of the Kalimantan Interconnection System frequency for the 2024 operating year in an effort to support the development of the Archipelago’s National Capital City (IKN) in East Kalimantan. The paper examines power system reliability and stability from published journals in the context of accomplishing Indonesia’s Sustainable Development Goals. This study explores Under Frequency Load Shedding (UFLS) and Under Voltage Load Shedding (UVLS) as important defense mechanisms to maintain system stability during abnormal conditions. The main focus of this study is the development of adaptive defense scheme (ADS) design based on frequency stability with load shedding by under frequency relay (UFR). This highlights the importance of frequency stability as measured by the nadir frequency and steady state frequency, in order to prevent system failure. This study reviews conventional and ADS, and concludes that the adaptive method optimizes load shedding and generation by utilizing real-time data, thereby improving power system stability resilience and minimizing outages.
