This project aims to improve power quality for a grid-connected wind energy system using a STATCOM. The objectives are to maintain unity power factor at the source, meet reactive power needs of the wind generator and non-linear load, and provide fast response using hysteresis current control for the STATCOM. MATLAB/Simulink software is used to simulate the system both with and without STATCOM. The simulation results show that with STATCOM, harmonic distortion is eliminated in the load current and power quality is maintained at the point of common coupling.
As the fifth in a series of tutorials on the power system, Leonardo ENERGY introduces its minute lecture on voltage and frequency control, using the analogy of a metal/rubber plate to demonstrate the centralised nature of frequency control, whereas voltage control is more a local matter.

The performance of the wind turbine and thereby power quality are determined on the basis of measurements and the norms followed according to the guideline specified in International Electro-technical Commission standard, IEC-61400. The influence of the wind turbine in the grid system concerning the power quality measurements are-the active power, reactive power, variation of voltage, flicker, harmonics, and electrical behavior of switching operation and these are measured according to national/international guidelines. The paper study demonstrates the power quality problem due to installation of wind turbine with the grid. In this proposed scheme STATic COMpensator (STATCOM) is connected at a point of common coupling with a battery energy storage system (BESS) to mitigate the power quality issues. The battery energy storage is integrated to sustain the real power source under fluctuating wind power.

The significance of power factor correction (PFC) has long been visualized as a technology requirement for improving the efficiency of a power system network by compensating for the fundamental reactive power generated or consumed by simple inductive or capacitive loads. With the Information Age in full swing, the growth of high reliability, low cost electronic products have led utilities to escalate their power quality concerns created by the increase of such “switching loads.” These products include: entertainment devices such as Digital TVs, DVDs, and audio equipment; information technology devices such as PCs, printers, and fax-machines; variable speed motor drives for HVAC and white goods appliances; food preparation and cooking products such as microwaves and cook tops; and lighting products, which include electronic ballasts, LED and fluorescent lamps, and other power conversion devices that operate a variety of lamps.

An Approach of D-STATCOM in Single Phase System with Power Quality ImprovementIJERA Editor
The paper describes the design of D-STATCOM in single phase for voltage interruption mitigation of fault in an unbalance system. Speed of response is higher than static var compensator (SVC) and harmonic emission is less than SVC that is why D-STATCOM is used in place of static var compensator. It validates the performance of D-STATCOM for improving power quality and harmonics. It provides a guide for utilities to have an appropriate choice of FACTS devices for enhancing stability. The work proposes a two pulse STATCOM configurations in which voltage source inverter uses IGBT as a switching device have been simulated using MATLAB/SIMULINK. Accordingly, simulation is first carried out to illustrate use of D-STATCOM in mitigating voltage interruption in single phase. The scope of the paper is to explore the D-STATCOM in single phase. Normally, D-STATCOM is not used in single phase, so an attempt has been made to introduce DSTATCOM in single phase load or household applications. Simulation results of 3KVAR D-STATCOM validate that integrated D-STATCOM with 230V, 91μF capacitor is suited for single phase system with voltage interruption mitigation capacit

3. INTRODUCTION
In integration of power generation system with grid we will
experience the power quality problems.
Power electronic based FACTS devices like STATCOM can be
effectively utilized to improve the quality of power supplied to the
customers The increasing use of power electronic based loads
(adjustable speed drives, switch mode power supplies, etc) to improve
system efficiency and Controllability is increasing concern for
harmonic distortion levels in end use facilities and on overall power
system.
4. Aim of the Project
To eliminate the harmonic contents (flickers,
variation of voltage, active and reactive power) by
using STATCOM with Battery Energy Storage
System( BESS).
5. Objective of the Project
The grid connected wind energy generation system
for power quality improvement by using STATCOM has
the following objectives.
• To maintains power factor as unity at the source end.
• To meet the reactive power to wind generator and
non-linear load.
• To provides hysteresis current controller for
STATCOM to achieve fast dynamic response.
6. FACTS devices
A Flexible Alternating Current Transmission System (FACTS)
is used to enhance controllability and increase power transfer capability
of the network. In most of the applications the controllability is used to
avoid cost intensive. Types of FACTS devices are
• Series Devices - SSSC,TCSC
• Shunt Devices - STATCOM,SVC
• Series-series devices - IPFC,UPFC
• Series-shunt devices - HVDC link
7. INTRODUCTION TO STATCOM
• STATCOM is a Static Synchron
-ous shunt Compensator.
• It is a solid state based power
converter version of the SVC .
• The capacitive or inductive output
currents can be controlled indepen
-dently from its AC bus voltage.
10. RENEWABLE ENERGY SOURCES
• Solar energy
• Wind energy
• Hydal energy
• Tidal energy
• Geothermal energy
• Biomass energy
• Ocean energy
The sources which will be replenished naturally in the course of
time.
11. WIND ENERGY
Wind is abundant almost in any part of the world.
Its existence in nature caused by uneven heating on the
surface of the earth as well as the earth’s rotation means that
the wind resources will always be available.
13. TYPES OF WIND FARMS
Based on the type of the generator, wind farms are classified
into two types:
1.Variable speed wind farm-Double fed induction generator.
2. Constant speed wind farm-synchronous generator.
DOUBLE FED INDUCTION GENERATOR:
The term doubly fed, refers to the fact that the voltage on
the stator is applied from the grid and the voltage on the rotor is
induced by the rotor-side converter. This system allows a variable-
speed operation over large, but restricted, range.
16. MATLAB
Advantages and Disadvantages of Simulink
•No Programming skills are required.
• Relatively easy to simulate and generate results.
•The source code is not available and hence it is not possible to
modify the simulation package.
The name MATLAB stands for MATrix laboratory.
MATLAB is a software package for high-performance
numerical computation and visualization it provides an
interactive environment with hundred of built-in function for
its own high level programming language.
32. CONCLUSION
To eliminate the harmonic content of the load current
the STATCOM-BESS control system is used. So that power
quality is maintained at the point of common Coupling. And
hysteresis current control scheme in the STATCOM is used for
the fast dynamic response. It also maintains voltage and
current in phase. That means unity power factor is maintained
at the source end.
