Power loss minimization

Definition

Power loss minimization is the process of reducing the amount of electrical energy that is lost as heat during the transmission and distribution of electricity. This is crucial for improving the overall efficiency of power systems, as excessive power losses can lead to increased operational costs and reduced reliability. By optimizing network configurations and component settings, power loss minimization contributes to more efficient energy usage and sustainability in electrical grids.
