The solar based grid-connected power system is becoming a very fast growing area due to the shortage of the fossil fuel energy and the great environmental pollution. But the grid continuously supplies the power even when load is not present. This cause harmful situation in and around the grid. In the proposed technique, First Zeta converter is designed using PID(Proportional Integral Differential)...
Deterioration of electric signal causes poor efficiency or low power factor. One of the main factors affecting the quality of electrical signal is presence of harmonic content due to different switching combination for various loads. The Matrix Converter is a single stage AC to AC power converter, which directly connects a three phase input to a three phase output without any large reactive components...
High penetration of Grid by various energy resources leads to intermittent voltage and frequency variations. To smoothen out these variations and to integrate energy resources to the grid, this paper proposes a multi-input matrix converter topology to integrate the ac and dc energy resources to the grid. This matrix converter is based on the indirect matrix converter operating in the reverse boost...
Online personal health record (PHR) enables patients to manage their own medical records in a centralized way, which greatly facilitates the storage, access and sharing of personal health data. With the emergence of cloud computing, it is attractive for the PHR service providers to shift their PHR applications and storage into the cloud, in order to enjoy the elastic resources and reduce the operational...
A wind generator system that employs a boost chopper and a permanent magnet synchronous generator is studied. By replacing the main circuit of generator and boost chopper with the equivalent circuit, the power and DC output voltage are obtained as a function of duty ratio of the boost chopper and generator rotational frequency. Maximum power from the generator characterized by the load and optimum...
This paper addresses the need of semantic component in the grid environment to discover and describe the grid resources semantically. We propose semantic grid architecture by introducing a knowledge layer at the top of Gridbus broker architecture and thereby enabling broker to discover resources semantically. The semantic component in the knowledge layer enables semantic description of grid resources...
