II SYSTEM DEVELOPMENT & ITS DESCRIPTION

Integrated wind farm is used and power quality analysis is performed.[6]

The integration of big wind farm will create new problems regarding the power quality.[7]

Technical details of Wind farm.[8]

The simulation model implemented in the MATLAB/SIMULINK. [9]

Renewable Energy Source (RES) integrated at distribution level is termed as Distributed Generation(DG).[10]

high penetration level of wind energy in distribution systems, as it may pose a threat to network is terms of Power Quality(PQ) issues , voltage regulation and stability. [11]

wind energy system integration issues and associated PQ problems are discussed.

As per the modeling and simulation of a case study, the power quality of the grid connected wind farm has been investigated at different wind velocity. [12]

III SIMULATION AND MODELLING

Wind turbines cause significant impacts on the power quality of their connected grid.

Voltage fluctuations produced by wind turbines are usually due to wind speed variations, power and voltage fluctuations.

This case presents simulations for numerical models of two wind turbine schemes, fixed and variable speed types, by using MATLAB/SIMULINK.[12]

In order to investigate the power system impact of wind turbines, it is essential to use accurate dynamic simulation models of wind turbines and power system.

11/12/2013 12

The models must correctly represent the dynamic behavior of the wind turbines in order to predict critical operation conditions at the one hand and to improve their dynamic performance at the other hand.

Hence, those wind turbine models have to be developed and implemented in dedicated power system simulation tools in order to facilitate study on the wind turbines´ interaction with the power system. MATLAB software tools build the basis for power system simulations .[13]

V. CONCLUSIONSmodeling and simulation of Indian wind farm by using

MATLAB/SIMULINK has been carried out.

In this case, simulations of wind turbine system to assess power quality that will affect the power system before actual installation have been performed. Because of the complexity of the model under study, the computational burden is high. Future work will focus on the reduction of simulation time and increase the solution accuracy.

This case investigated the possible approaches for integration of FSIG wind farms to the power network.

This case presents the performance analysis of grid connected wind farm by using MATLAB/SIMULINK for power quality Analysis.

Power Quality issues of high penetrated grid connected wind farm has been investigated.
