In the dynamic realm of electrical power systems, the pervasive threat of disturbances ranging from minor fluctuations to major outages, necessitates robust protection mechanisms far beyond conventional equipment based defenses. This study introduces an innovative Adaptive Defense Scheme tailored for the Cirata’s subsystem, addressing the critical need for a dynamic responsive protection strategy that aligns with the fluctuating nature of power system operations. Traditional protection schemes characterized by their static approach fall short in accommodating the variability and unpredictability inherent in power systems, leading to potential vulnerabilities in system stability and reliability. By leveraging an Adaptive Defense Scheme, this study aims to bridge this gap by presenting a methodological advancement that dynamically adjusts to the evolving conditions of supply and demand. Employing the DIGSILENT PowerFactory software, it designs a suitable Adaptive Defense Scheme method for the Cirata’s subsystem through comprehensive simulation scenarios. These scenarios represent a spectrum of potential system conditions thereby facilitating an extensive evaluation of the Adaptive Defense Scheme’s performance. The incorporation of brute force technique enhances the scheme's decision making process, optimizing effective load shedding strategies to maintain system balance and prevent cascading failures. The core outcome of this study is the development of an Adaptive Defense Scheme that demonstrates adaptability to various system conditions while adhering to PLN's operational standards. The simulation results validate the Adaptive Defense Scheme’s efficacy in securing the power system against a wide range of disturbances thereby ensuring system stability within acceptable limits. Through strategic load shedding and potential subsystem interconnection, the Adaptive Defense Scheme effectively mitigates the impact of system deficits showcasing its superiority over conventional protection methods. This study concludes that the designed Adaptive Defense Scheme substantially enhances the security and performance of the Cirata’s subsystem, offering a proactive intelligent solution to contemporary challenges in power system protection. The findings underscore the potential of integrating adaptive schemes and brute force technique in advancing power system defense mechanisms setting a precedent for future research and implementation in the field.
