Energy Loss Management in Distribution Networks

Energy loss management in distribution networks addresses the reduction of electrical losses that occur between substations and end users. These losses arise from resistive heating in conductors, transformer inefficiencies and reactive power flows. Effective management is critical for enhancing system efficiency, lowering operational costs and meeting regulatory targets for energy efficiency and carbon reduction. Recent advances encompass both passive measures—such as network reconfiguration and phase balancing—and active solutions, including decentralised optimisation algorithms, on‐load tap changing and integration of energy storage. The proliferation of smart grid technologies and distributed generation has further enabled granular monitoring and adaptive control, allowing operators to target loss hotspots, improve voltage profiles and accommodate variable renewable inputs. Globally, these developments underpin the transition to more resilient, low‐carbon power systems and support the scalable deployment of renewable energy at the distribution level.
