Case Study Feasibility Analysis of Renewable Energy Supply Systems in a Small Grid Connected Resort By Jody Robins Dr. Robert Woods, Committee Chair Professor of Hotel Management University of Nevada, Las Vegas This paper presents a case study on the feasibility of a small grid connected resort in the marine west coast climate of Canada to implement a renewable energy supply system. The current...

This paper deals with a wind-based stand-alone generating unit with Permanent Magnet Synchronous Generator (PMSG) and a Lead Acid Battery (LAB) for energy storage, during wind speed variation as well as transient performance under variable load. The main purpose is to supply 230 V/50 Hz domestic appliances through a single-phase inverter. Simulations and experimental results validate the stabil...

In this research paper an energy system composed of three energy conversion devices namely, photovoltaic panels, a wind turbine, and a battery is proposed. This controller directs power to a fixed voltage DC bus. The fixed voltage bus supplies the load, while the excess power is directed to the batteries. Simulation and control of a hybrid PVwind generator system connected to the load are prese...

This paper presents a control strategy for a grid connected doubly fed induction generator (DFIG)-based wind energy conversion system (WECS).Control strategies for the grid side and rotor side placed in the rotor circuit of the Doubly Fed Induction Generator (DFIG) are presented along with the mathematical modeling of the Wind Energy Conversion System. In this control approach, wind generators ...

The concern for environment due to the ever increasing use of fossil fuels and rapid depletion of the conventional sources of energy has led to the development of alternative sources of energy. Wind energy, the kinetic energy associated with movement of large masses of air, is an inexhaustible source of energy which generates electricity without harming our environment. But it is unreliable ene...

With the change in the wind profile, the speed of doubly fed induction generator (DFIG) of wind energy conversion system (WECS) changes from super synchronous to sub synchronous range and vice versa. DFIG is operated to generate quality power; hence, power at rotor side is controlled using matrix converter taking power from grid and feeding back power to the grid depending on the wind profile. ...

This paper presents Growing Neural Gas (GNG) based a maximum power point tracking (MPPT) technique for a high performance wind generator using DFIG. It is used in variable speed wind energy conversion system. Here, two back to back converters is used and connected to the stator, correspondingly FOC and VOC is done on machine and supply side converter. Constant voltage over the grid is obtained ...

A frequent challenge for wind energy applications is to grasp the impacts of turbulent wind fields properly. The wind turbine power performance curve, usually determined applying the IEC standard 61400-12, provides a functional relation between the measured wind speed u and the corresponding power output P of the turbine. But it is not sufficient to describe the actual dynamics of the power out...
