RENEWABLE ENERGY INTEGRATION IN SMART ELECTRICAL NETWORKS: ADVANCED POWER SYSTEM STRATEGIES FOR SUSTAINABLE ENERGY TRANSITION

Abstract

The integration of renewable energy resources into smart electrical networks emerged as a critical requirement for achieving sustainable energy transition and reducing dependence on fossil-fuel-based electricity generation. This study examined the influence of advanced power system strategies on renewable energy integration and sustainable energy transition within modern smart electrical networks. The research focused on Smart Grid Technologies, Energy Storage Systems, Demand-Side Management, and Artificial Intelligence-Based Optimization as key determinants of sustainable energy performance. A quantitative research design was employed, and data were collected from a sample of 320 professionals working in electricity utilities, renewable energy organizations, power system engineering firms, and energy regulatory agencies. Statistical analyses included descriptive statistics, Pearson correlation analysis, and multiple regression analysis. The findings indicated that Artificial Intelligence-Based Optimization exerted the strongest influence on Sustainable Energy Transition (β = 0.385, p < 0.001), followed by Smart Grid Technologies (β = 0.341, p < 0.001), Energy Storage Systems (β = 0.298, p < 0.001), and Demand-Side Management (β = 0.267, p < 0.001). Correlation analysis revealed significant positive relationships among all study variables, with Artificial Intelligence-Based Optimization demonstrating the strongest correlation with Sustainable Energy Transition (r = 0.781, p < 0.01). The regression model explained 69.4% of the variance in Sustainable Energy Transition (R² = 0.694). The study concluded that advanced power system strategies significantly enhanced renewable energy integration, improved grid efficiency, strengthened system reliability, and accelerated sustainable energy transition. The findings provided valuable implications for policymakers, utility providers, and energy planners seeking to develop resilient and environmentally sustainable electrical networks.
