Subject review Total power losses in a power system consist of technical losses and commercial losses. Commercial losses are 30-40 % of total losses and appear as a result of unreliable measurement devices for electricity registering and wilful unauthorised consumption of electricity. It is almost impossible to find illegal connections in a distribution power system due to hidden main power cab...

Individually Network reconfiguration or Capacitor control perform well in minimizing power loss and improving voltage profile of the distribution system. But for heavy reactive power loads network reconfiguration and for heavy active power loads capacitor placement can not effectively reduce power loss and enhance voltage profiles in the system. In this paper, an hybrid approach that combine ne...

In this paper, a combinational optimization algorithm is introduced to obtain the best size and location of Static Compensator (STATCOM) in power systems. Its main contribution is considering contingency analysis where lines outages may lead to infeasible solutions especially at peak loads and it commonly can be vanished by load-shedding. The objective of the proposed algorithm is firstly to pr...

Sandia's Z machine used water as both an insulator in power storage components as well as a switching media. The anomalously high energy density, coupled with its high dielectric strength, allow flor a significant reduction in size over a gas insulated design. Moreover, the h g h currents required to produce ICF demand a low inductance design, which is aided by the high electrical breakdown str...

We demonstrate that almost all nonparametric dimensionality reduction methods can be expressed by a simple procedure: regularized loss minimization plus singular value truncation. By distinguishing the role of the loss and regularizer in such a process, we recover a factored perspective that reveals some gaps in the current literature. Beyond identifying a useful new loss for manifold unfolding...

Electrical steels are important alloys widely used in electrical instruments. The magnetic properties and low core loss of grain oriented silicon steels are closely related to the sharpness of Goss texture ({110} ).The direction of is the softest direction for magnetism.  In this work, the microstructure and dependence of orientation density along the major texture fibers on the applied cold ro...

Power system losses can be divided into two categories: technical losses and non-technical losses. Technical losses are naturally occurring losses (caused by actions internal to the power system) and consist mainly of power dissipation in electrical system components such as transmission lines, power transformers, measurement systems, etc. Technical losses result from the impedance of the netwo...

As Distribution Systems are growing large and being stretched too far, electric utilities and end users of electric power are becoming increasingly concerned about meeting the growing electric demand. Hence efforts have been made by electric utilities to reduce the losses in the distribution system. In this dissertation work, Network Reconfiguration and Optimal Distributed Generation placement ...

In this paper, we conduct a techno-economic analysis of a 1000 MWe solar tower aided coal-fired power generation system for the whole life cycle. Firstly, the power output (from coal and solar thermal energy) under variable direct normal irradiance and grid demand are studied. Secondly, a financial assessment is performed, including profits and losses of the plant project. Thirdly, sensitivity ...

Power dissipation due to leakage current in the digital circuits is a biggest factor which is considered specially while designing nanoscale circuits. This paper is exploring the ideas of reducing leakage current in static CMOS circuits by stacking the transistors in increasing numbers. Clearly it means that the stacking of OFF transistors in large numbers result a significant reduction in powe...
