This review examines advanced methodologies for optimal power flow (OPF) in integrated energy systems (IES), highlighting the integration of diverse energy forms like electricity, heat, and gas. It focuses on decoupled algorithms and developments for gas-electric systems and the impact of renewable energy sources and electric vehicles, which introduce significant uncertainties into OPF. The paper also addresses the cybersecurity challenges, especially false data injection risks. Future directions include advancing predictive control systems, improving energy storage, and evolving regulatory frameworks to facilitate sustainable IES development. This synopsis aims to guide future research efforts in enhancing the efficiency and reliability of multi-energy systems.
