The use of dynamically adjustable power supplies as a method to lower power dissipation in DSP is analyzed. Power can be reduced substantially without sacrificing performance in fixed-throughput applications by slowing the clock and lowering supply voltage instead of idling when computational workload varies. This can yield a typical power savings of 30–50%. If latency can be tolerated, bufferi...

We compare the demand of a large electricity consumer with supply given by wind farms installed at two distant geographic locations. Obviously such situation is rather unrealistic, however our main goal is a quantitative characterization of the intermittency of wind electricity. The consumption pattern consists of marked daily and weekly cycles interrupted by periods of holidays. In contrast, w...

The reliability standards for electricity supply in a developing country, like Nigeria, have to be determined on past engineering principles and practice. Because of the high demand of electrical power due to rapid development, industrialization and rural electrification; the economic, social and political climate in which the electric power supply industry now operates should be critically vie...

In this paper, we develop a modeling and computational framework that allows for the determination of optimal carbon taxes applied to electric power plants in the context of electric power supply chain (generation/distribution/consumption) networks. The adoption of carbon/pollution taxes both internationally and regionally has been fueled by global climate change and fuel security risks with a ...

A switching mode power supply (SMPS) is a hopeful candidate for the 1MW CW klystron power supply of KOMAC (KOrea Multi-purpose Accelerator Complex). The merits of the SMPS are low stored energy, small size, high rating efficiency and possible cost saving whereas the demerits are EMI problem and system complexities. The proposed power is 2MW and it is considered that the modules, each of which h...
