The focus of this paper is on the design and implementation of a critical program in structural biology onto two computational and data grids. The first is the Buffalo-based ACDC grid, which uses facilities at SUNY-Buffalo and several research institutions that are under distinct control. The second is Grid2003, the iVDGL grid established late in 2003 primarily for physics and astronomy applica...

In this paper, a supervisory controller is proposed to manage the power flow in a hybrid AC/DC micro-grid for both grid-connected and disconnected modes. When the hybrid AC/DC micro-grid is connected to the utility grid, power surplus or shortage leads to power trade between the micro-grid and the utility grid. In the grid-disconnected mode, the renewable power sources (wind and solar generatio...

As an efficient alternative to fossil fuels, renewable energy sources have attained great attention due to their sustainable, cost-effective, and environmentally friendly characteristic. However, as a deficiency, renewable energy sources have low reliability because of their non-deterministic and stochastic generation pattern. The use of hybrid renewable generation systems along with the storag...

In the present scenario, the increasing penetration of solar energy can be significant challenge due to the variation of power generation. One of the solution to improve the quality of power supply and guarantee of system stability is energy storage system(ESS). In this project, a AC-DC hybrid micro grid is designed based on photovoltaic (PV), generator and energy storage system are coordinated...

This thesis first proposes a hybrid ac/dc micro-grid and its coordination control for reducing the processes of multiple conversions in an individual ac or dc grid. Renewable energy based distributed generators (DGs) play a dominant role in electricity production, with the increase in the global warming. Distributed generation based on wind, solar energy, biomass, mini-hydro along with use of f...

A micro grid consists of cluster of loads and distributed generators that operate as a single controllable system. As an integrated energy delivery system micro grid can operate in parallel with or isolated from the main power grid. The micro grid concept introduces the reduction of multiple reverse conversions in an individual AC or DC grid and also facilitates connections to variable renewabl...

This paper presents the simulation technique for simulating a micro grid (MG) and the analysis results of the operating characteristics of a MG with a hybrid power source. The hybrid power source in this research included both a diesel engine generation set and a wind generation system. The simulation tool adopted by this research is the professional software, Simulink. The simulation results a...

Distributed generator (DG) is an increasing interest in using not only to inject power into the grid, but also to enhance the power quality. In this paper, a space voltage pulse width modulation (SVPWM) control method and current double closed loop control strategy is proposed for DG converter in a wind-solar-storage hybrid micro grid system. This method is based on the proper topology of three...

Micro-grid is a kind of distributed low-voltage supply network by integrating various distributed powers, energy storage systems and controlled load. In micro-grid, distributed power can be divided into certain and stochastic power. The prediction on supply capacity of micro-grid focuses on electric energy production by stochastic power. The wind energy power is predicted in this paper by suppo...

Grid computing integrates heterogeneous, geographically distributed, Internetready resources that are administered under multiple domains. A key challenge in grid computing is to provide a high quality of service to users in a transparent fashion, hiding issues that include ownership, administration, and geographic location of a wide variety of resources that provide compute cycles, data storag...
