Overview

With the increasing integration of renewable energy resources (RERs), energy storage resources (ESRs), and electric vehicles (EVs), power system operation has become more complex. Demand response mechanisms, enabling end-users to manage electricity usage during peak hours, add another layer of sophistication to energy management. Additionally, sector coupling, which bridges energy supply and end-use sectors, is gaining global attention as a method to enhance system efficiency, flexibility, and reliability.The reprint of the Special Issue "Power System Analysis, Control, and Operation" addresses the growing challenges and innovations in modern and future power systems. It compiles advanced research on topics such as power grid operation, optimal power flows, and the integration of RERs, ESRs, EVs, and distributed energy resources. It also explores data analytics, forecasting methods, and strategies for improving grid sustainability, reliability, and resilience. Studies on cross-sector coordination, such as the interaction between power and transportation systems, and sector coupling solutions further emphasize the need for innovative approaches to energy system integration.The collection offers valuable insights for researchers, professionals, and policymakers working to address technical challenges, close research gaps, and advance the design of smart, sustainable energy systems in an increasingly interconnected world.
