Electrical Distribution Reliability

Risk and reliability assessment for electrical distribution systems and impacts of regulations with examples from Sweden

The introduction of performance based tariff regulations, and higher media and political pressure have increased the need for well-performed asset management in the operation and planning of electrical distribution systems. In this paper quantitative reliability assessment methods are proposed as a tool to meet these new incentives. Electrical distribution systems have compared to other technic...

Reliability improvement in radial electrical distribution networkᅡᅠby optimal planning of energy storage systems

This paper provides an optimal approach to denote the location and size of ESSs (energy storage systems) with the intention of reliability improvement in radial electrical distribution networks. The proposed optimal ESSs planning is addressed as a minimization problemwhich aims at minimizing the cost of ENS (energy not supplied) as well as ESSs costs at the same time, subject to safe operation ...

Basic Reliability Analysis of Electrical Power Systems

Electrical Reliability of RF Power GaAs PHEMTs

GaAs PHEMTs are broadly used in RF power applications for wireless systems. A major concern with these devices is their gradual degradation as a result of prolonged biasing at high voltages. Previous research has identified the drain side of the device as the region that sustains most of the damage [1], but other mechanisms involving charge modulation under the gate [2] have also been reported....

Reliability Testing by Precise Electrical Measurement

Manyof the lllechanismsthat lead to the ultimate failure of an integrated circuit maybe evident early in the life of a device and should be detectable if sufficiently precise electrical llleasurements are made. A variety of tests have been I114deon mediumscale CMOScircuits to evaluate this hypothesis. These have included leakage current, transient current, electrical noise, upper cut off freque...
