This paper presents a classification approach based on the power components and applied to the Non-Intrusive Load Monitoring (NILM). The active, reactive and apparent power levels are recorded and are fed to a Decision Tree (DT) classifier to develop the appropriate classification model. The results have shown that using the change in the power components level instead of using the actual power components...
Islanded operation of power systems with a shortage of generation to meet the local demand may experience a dip in frequency which could potentially damage the system equipment unless proper action is taken to shed loads in a timely manner. Recent research has shown that the uncertainty associated with estimating the amount of load to be shed can be better handled by fuzzy systems; however, there...
A utility has recently installed a conservation voltage reduction (CVR) system on multiple distribution substations in order to test, measure and verify the performance of the system, as well as provide peak demand and energy reduction. The testing of the system is to determine the effects of particular CVR implementations on customers' loads, while maintaining voltages within the ANSI C84.1 standard...
The main goal of the model coil is to demonstrate the feasibility of ‘Insulation-Wind-React’ manufacturing process and to confirm the feasibility of the superconducting outsert design. The model coil was wound with Cable-in-Conduit Conductor (CICC) using restacked-rod process (RRP) strand, and cooled with forced-flow supercritical helium with inlet temperature of 4.5 K. The test...
The widespread usage of more efficient but potentially harmonic rich residential loads such as CFL (Compact Fluorescent Light) lamps can be expected to contribute to increased harmonic levels in distribution systems. In some cases, additional distortion can push already high harmonic levels above the recommended limits. Also, the impact can be further exacerbated by the presence of reactive compensation...
Managing grid assets is an ongoing task for electricity distribution network operators (DNOs). Deep uncertainties especially in energy sustainability and flexibility make it difficult to forecast future electricity demand and corresponding grid capacity need. This makes long-term asset replacement strategy planning a complex issue. In this paper, a modeling method that uses the `sub-grid' concept...
Power systems' operators have the task of maintaining the balance between the demand and generation of electric power. Much research and attention is being given to find more environmental friendly sources of power generation. Naturally, more power is required when the load is at its peak value, and this tends to be when the most non environmentally friendly sources of power generation are used. This...
