Turning to Renewable Energy Sources (RES) is the most logical politics in securing the modern society from critical changes in earth increasing temperature. However, Distributed Generation (DG) sources could lead to new challenges in electricity network, mainly allocation of DG sources in distribution level of power system will set the existing network under stress of power flow parameters. The...

introduction: management is one of the most important factors for life, development, growth or death of any organizations including hospitals. the power is of one of the main concepts that by focusing on the fundamental and theoretical efforts considered as an important factor at all levels of management and human resources. managers who know the sources of power and are using them, have more e...

This paper presents a balanced active and reactive power control, using a Phase Locked Loop for synchronization, and applied to a grid connected Five Level Inverter. The energy source of the system can be a photovoltaic generator or a wind turbine. We size the passive elements of the system and explain the value of the system architecture using a Five Level Inverter when compared to a classical...

this paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. the hybrid dc power sources are connected to grid using power electronic converters include dc-dc converter and grid connected voltage source inverter. the power from hybrid power sources is controlled during voltage sag by designing of control strategy for dc-dc converter....

This article agrees with recent arguments suggesting that normative and epistemic power is rife within global health policy and provides further examples of such. However, in doing so, it is argued that it is equally important to recognize that global health is, and always will be, deeply political and that some form of power is not only necessary for the system to advance, but also to try and ...

In this paper the results of EMC tests wideband power sources: PWM-based source and audio amplifier are discussed. They intended to be used supply measuring system developed for evaluation transformation accuracy instrument transformers. Therefore, it is required detect possible interferences that may caused by its operation cause a decrease in accuracy. The concern conducted emission frequenci...
