To build a large-scale renewable energy integrated system in the power system, power fluctuation mitigation and damping measures must be implemented during grid connection. PID damping controllers and traditional intelligent controllers with pole configuration are usually used for improving damping. Integration of large wind power plants and photovoltaic power plants into the power system faces transient power oscillation and fault ride-through (FRT) capability under fault conditions. Therefore, this paper proposes a static synchronous compensator (STATCOM) damper based on a recurrent Petri fuzzy probabilistic neural network (RPFPNN) to improve the transient stability of the power system when large offshore wind farms and photovoltaic power plants are integrated into the power system, suppress power fluctuation, and increase FRT capability. To verify the effectiveness of the proposed control scheme, a three-phase short circuit fault at the connected busbar is modeled in the time domain as part of a nonlinear model. From the comparison of simulation results, the proposed control scheme can effectively slow down the transient fluctuation of power supply to the grid-connected point when the grid is faulty, reach steady-state stability within 1–1.5 s, and reduce overshoot by more than 50%. It can also provide system voltage support at an 80% voltage drop and assist in stabilizing the system voltage to increase FRT capability. It also improves stability more than PID controllers when disturbances are present. Therefore, it maximizes the stability and safety of the power grid system.

Introduction Accurate measurement is foundational to psychological assessments, influencing research validity, clinical practice, and societal applications. While extensively utilized, traditional scoring methods suffer from limitations in granularity, sensitivity, and adaptability, potentially impacting the precision and utility of these assessments. This study aims to explore the efficacy of fuzzy logic as an alternative scoring method for the Satisfaction with Life Scale (SWLS), addressing these limitations. Methods A cross-sectional design involving 1,230 Greek adults was employed to compare traditional scoring methods with fuzzy logic. Data were collected online and analyzed using descriptive statistics, Pearson correlation, paired t-tests, regression analysis, and sensitivity analysis to evaluate the robustness and reliability of fuzzy logic scoring. Results Results indicated that fuzzy logic scoring provides enhanced granularity and sensitivity, effectively capturing subtle variations in life satisfaction and mitigating ceiling and floor effects. The strong positive correlation (r = .9505) between traditional and fuzzy logic scores suggests high consistency. Significant mean differences highlighted the increased sensitivity of fuzzy logic scoring. The Bland-Altman plot confirmed good agreement between the methods, and sensitivity analysis demonstrated the robustness of fuzzy logic scoring across different parameter settings. Conclusion In conclusion, fuzzy logic offers a reliable and nuanced alternative to traditional scoring methods, significantly improving the accuracy and applicability of psychological assessments. Integrating fuzzy logic with advanced technologies could further enhance the precision and inclusivity of psychological evaluations, making it a promising tool for future psychological measurement.
