PERFORMANCE EVALUATION OF SMART GRIDS FOR OPTIMIZED ENERGY MANAGEMENT IN SMART CITIES

Abstract

This study evaluates the performance of smart grids in optimizing energy management within smart cities, focusing on key metrics such as energy efficiency, grid reliability, renewable energy integration, demand-side management, and cost-effectiveness. Using a mixed-methods approach, the research analyses data from case studies in five smart cities, supplemented by interviews and secondary data sources. The findings indicate that smart grids significantly enhance energy optimization, with cities like City C exhibiting superior performance in terms of energy loss reduction (20%), fault detection efficiency (95%), and renewable energy integration (35%). Furthermore, demand-side management strategies proved effective, with smart meter penetration in City C reaching 85%, resulting in an 18% reduction in energy consumption. Smart grids delivered favourable financial returns through positive ROI and future cost savings to the cities. The achieved results illustrate how smart grids create opportunities for improved energy management and reduced operational expenses with complementary sustainable practices in cities. The study shows developing cities face two major problems involving money issues and technology standards. Further development of smart grid technology and advanced analytics demands ongoing financial support because it ensures both high performance and scalability for urban environments.
