Solar PV System – A Review
Jeetu Khan*, Piyush Jain, Vijay Bhuria
Department of Electrical Engineering, Madhav Institute of Technology and Science
Gwalior, Madhya Pradesh, India
Abstract Solar energy is the best clean alternative energy resource. During shading condition arrays
can be treated as an asymmetrical DC source for multilevel inverter, based on insulation
level, sets of PV panels are formed to act as DC source. During shading condition, based on
insulation level sets of PV panels are allocated to multilevel inverter to as asymmetric
source. With the growing research in multilevel inverter there are many topologies have been
conceptualized which are having advantage over the conventional inverters. By allocating as
asymmetric source the lesser source higher number of levels can be synthesized and the
MPPT complexity can be reduced. The review of this paper toward the comprehensive
analysis of conventional and novel cross connected source MLI topologies with reduced
count for asymmetric source configuration for Solar PV application, as all cross connected
source MLI cannot be implemented for asymmetric source configuration.
Keywords: multilevel inverter, maximum power point tracking (MPPT), solar PV, total
harmonic distortion (THD)
INTRODUCTION
In India Government-funded solar
electricity was approximately 6.4 MW per
year as of 2005. India is ranked number
one in terms of solar electricity production
per watt installed, with an insulation of
1,700 to 1,900 kilowatt hours per kilowatt
peak (kWh/KW). 25.1 MW was added in
2010 and 468.3 MW in 2011.
As of 31 August 2015, the installed grid
connected solar power capacity is 4,229.36
MW and India expects to install an
additional 10,000 MW by 2017, and a total
of 100,000 MW by 2022. Currently, there
is urgent need and hence, a growing trend
toward using environmentally clean and
safe renewable power sources, such as
wind and solar-photovoltaic (Solar-PV),
which are heavily dependent on PE.
Solar energy is one of the clean energy
sources. Only 0.026% of available solar
energy is converted into electricity. During
shading condition solar PV arrays are
treated as a asymmetrical DC source for
multilevel inverter based on the insulation
level, PV panels formed to act as a DC
source. With the growing research in
multilevel inverter there are many
topologies have been conceptualized
which are having advantage over the
conventional inverters .Due to
asymmetrical source Configuration the
MMPT complexity can be reduced , also
number of source for multilevel reduced
for higher level configuration.[1-3]

Analysis of THD in Voltage Source Inverter With Constant
Current Controller for Solar PV Cell
D. Elavarasan*, S. Kaliappan Department of EEE, Kumaraguru College of Technology, Coimbatore, India
Abstract
A common method in the study of voltage source inverters is the hypothesis of a voltage-type
input source even in the case of renewable energy (RE). When a converter is supplied by an
RE, such as a photovoltaic (PV) generator, the dc-link voltage is usually controlled by the
converter with closed loop to extract maximum power from the source. The main aim of the
paper is to analyze the total harmonic distortion with current controller technique in three
level voltage source inverter and to reduce the harmonics by using filter to connect it to grid.
The use of perturb and observe MPPT will help to produce high output efficiency from solar
PV cell. The simulation results for total setup is given in the paper and the THD values are
calculated for voltage source inverter (VSI).
Keywords: MPPT tracker, perturb and observe algorithm, single ended primary inductance
converter (SEPIC), solar PV cell, voltage source inverter, total harmonic distortion
INTRODUCTION
The discovery of internal combustion
engine resulted in the use of petroleum
products(petrol, diesel and natural gas) to
fulfill our energy requirements. The fossil
fuels (coal, oil and gas) either used directly
or converted to electricity and transported
to be used in industries and homes. The
use of energy plays an important role in
one’s life. Since the use of energy has
become an integral part of our life, its
supply should be secure and
sustainable.[1,2]
At the same time, it should
be economical, environmentally friendly
and socially acceptable. The current trends
in energy consumption are either neither
secure nor sustainable. The raising
consumption of fossil fuels and associated
prices, together with increase in green-
house gas emission, threatens our secure
energy supply.[2]
Therefore, development
of clean, secure, sustainable and affordable
energy sources should be our priority in
this century.
Renewable energy (RE) or Non-
Conventional energy sources(NCES)
enables you to reduce the carbon dioxide
(CO2) that goes into the atmosphere
because of the energy we use like fossil
fuel, which is known as our carbon
footprint. Consuming renewable sources
like solar energy and wind energy, we also
reduce our necessity on fossil fuel gas and
oil reserves, which are becoming
expensive and hard to find.[3]
It also
reduces our dependence on imported fossil
fuels, improving our energy security.
Tracing the maximum power point (MPP)
of a photovoltaic (PV) array is a vital part
of a PV system. As such, many MPP
trackers (MPPT) have been developed and
implemented. The methods vary in
complexity, sensors required, cost,
convergence speed, popularity, range of

A STATCOM-Based Control Strategy for Power Quality
Improvement in a Hybrid Nonautonomous Power System
T. Seenivasagam, C.K. Aravind*
Department of Electrical and Electronics Engineering, V.V. College of Engineering, Tirunelveli, India
Abstract
Power generating from solar and wind systems are more reliable and they have many
advantages compare with conventional power generation systems. However, these solar and
wind power systems are unpredictable in nature and varying with atmospheric conditions.
When they operating alone they are poor power sources. Fortunately, these problems can be
overcome by integrating these power sources. However, when these hybrid systems are
interconnected to utility grid induce power quality problems. This paper deals about the
power quality issues in hybrid power systems due to reactive power and harmonics. In this
system a static compensating device is connected to the common coupling point to reduce the
power quality problems. The control strategy for the hybrid power system is simulated using
MATLAB/SIMULINK and it confirms the efficacy of the system.
Keywords: hybrid system, power quality, STATCOM, solar, wind
INTRODUCTION
onventional energy sources like coal, gas
and oil are depleting all over the world.
Moreover, these sources are considered to
be main reason for environment pollution.
So, the best solution to meet increasing
energy demand problem and also to
produce clean energy the power can be
produced from renewable energy sources
like wind, solar, hydro and tidal.[1-4]
Among various renewable energy sources
wind and solar systems are widely used.
Stand-alone renewable energy systems
with single source either photovoltaic (PV)
or wind generator is highly unreliable due
to its intermittent nature. So, hybrid
schemes combining PV and wind can be
employed. Moreover, hybrid systems with
PV and wind are considered to be highly
reliable due to the complementary nature
of the resources. Hybrid systems can be
used to supply the remote loads where
utility connection is not possible or it can
be connected to a utility grid. Suitable
power electronic interface should be
designed to integrate PV and wind
generators and to connect the hybrid
system to isolated load or to utility
network.
Power quality problems are induced in the
power grid systems when the distributed
generation systems are connected to it. It
reduces power system reliableness and
may induce over voltage, over current and
safety issues. Generally solar arrays power
convention is based on climate conditions.
It can create power interferences like
harmonics, frequency oscillation and
voltage fluctuations in the utility grid.[5,6]
In PV system, at low irradiation may result
to unpredictable distortion in the character
of the signal, overstepping the norms of
standard grid connection codes. The
inverters which are used in PV systems
may cause mal-operation because of

Abstract
Permanent Magnetic Synchronous Motors (PMSM or Brushless DC Motor) are widely being
used for many industrial applications because of their high efficiency, high torque and low
volume. Research has conducted using genetic algorithm to develop a complete model of the
BLDC motor and to design an optimal controller for its position control. Generally PID
controller is being used for control purposes in many systems because of its simple structure
and easy implementation. However, in practice, we often do not get the optimum performance
with the conventionally tuned PID controllers. For this purpose, Artificial Intelligence based
Genetic Algorithm is proposed as an optimizer to find the optimized PID gains for the
position control of PMSM motor. Comparison was made with the traditional method.
Simulation results showed that PID control tuned by GA provides more efficient closed loop
response for position control of PMSM motor. MATLAB/SIMULINK software package was
used for the modelling, control and simulation of the PMSM motor.
Keywords: artificial intelligence, optimized PID controller, permanent magnet synchronous
motor, pulse width modulation
INTRODUCTION
BLDC engines are exceptionally
mainstream in territories which require
elite due to their littler volume, high
compel, and straightforward framework
structure. By and by, the configuration of
the BLDCM drive includes a mind
boggling process, for example, displaying,
control plan choice, reenactment and
parameters tuning and so on.
A specialist learning of the framework is
required for tuning the controller
parameters of servo framework to get the
ideal execution. As of late, different
present day control arrangements are
proposed for the ideal control outline of
BLDC motor.[1,2]
However, these strategies
are mind boggling in nature and require
over the top calculation. Interestingly, PID
control gives a straightforward but then
powerful answer for some control
problems.[3]
In spite of the fact that PID controllers
have a straightforward structure however it
is very testing to discover the enhanced
PID picks up. The proceeding with
execution changes of computational
frameworks have made Genetic Algorithm
(GA) suitable for finding worldwide ideal
answer for control framework, for
example, the hunt of optimal PID
controller parameters.[4,5]
In this paper, extensive modeling of a
BLDC motor and GA-based PID scheme
is proposed for its position control. The
paper is organized in the following manner

INTRODUCTION
Historically the first grid-connected Photo-
Voltaic (PV) plants were introduced in the
1980andnow a day’s grid-connected
systems are growingfast with the use of
Photo-Voltaic technology. All
thesesystems use an inverter to transform
the DC electricity from the PV arrayinto
AC. Grid-connected inverterstotally differ
from stand-alone inverters.
An MPPT is usually incorporated withthis.
Normally, electricity can flow either out of
the building fromexcess on-site PV power
generation, or into the building with
inadequate PVgeneration. Both the
exported and the imported energy can be
metered. (Figure 1)
Each PV module is a nonlinear system so
that its output power isinfluenced by solar
irradiation and weather conditions. In
order to match the nonlinear output of PV
modules with the load for all atmospheric
conditions, a maximum power point
tracking(MPPT) technique is usually
implemented and applied to a grid-
connected system to find and track the
maximum power point of the PV panel.
The MPPT algorithm is appliedto the
power conversion stage for adjustment of
the system operating point.Therefore, each
grid-connected PV system has to perform
two essential functions:[1-4]
To extract maximum power output
from PV arrays
To inject an almost harmonic free
sinusoidal current into the grid.
Currently, grid-connected power
converters are based on modern power
semiconductor devices operating in
switched mode, but we simulate it for most
basic concept in which thyristors are used.

Artificial Neural Networks-Based Four-Leg Matrix Converter for
Linear and Nonlinear Load

India
Abstract
The 4-leg matrix converter, which it is capable of providing a 3-phase plus neutral supply
from a standard balanced 3-phase source. Tralatitious 3x3 matrix converters deliver
bounded use in this application as they are only capable of supplying a poised three-phase
payload. It would be suitable to be able to power unbalanced and nonlinear loads, requiring
that the converter provides a neutral connection .This goal can be achieved by extending the
number of output legs in the matrix converter to four .The fourth leg of MC is required in
order to provide an electrical path for the circulation of the zero -sequence current in the
load. The space vector modulation technique is use to provide a switching pattern for matrix
converter using ANN. The SVM technique is an extension method, which is currently used in
3x3 matrix converters, and then it accords the dissociated restraint of both the input and
output .The matrix converter is a nonlinear controller because it uses nonlinear components.
ANN controller is an approach to overcome the waveform quality problem. A simulation in
the MATLAB / SIMULINK platform has validated the proposed idea.
Keywords: artificial neural networks, matrix converter, space vector pulse width modulation,
total harmonic distortion
INTRODUCTION Recent years have witnessed an increase in
demand for low cost, small size and highly
efficient converters. Matrix converters are
best suited for such applications.
These AC–AC converters are capable of
converting an AC input of fixed amplitude
and frequency to an AC of variable
amplitude and frequency without
converting it to DC as in inverters. Matrix
converters have various appealing features
like compact circuit, sinusoidal currents
and bidirectional energy flow.
These guarantee higher efficiency, longer
lifespan and fewer input harmonics than
inverters.[1]
Four-leg MCs, featuring a neutral
connection as shown in Figure 1, can be
used to produce a balanced output voltage
even under highly unbalanced or nonlinear
load conditions. Twelve bidirectional
switches are used in the converter, each
one compiled by two IGBTs and two
diodes. In general the switching of the
IGBTs in each bidirectional switch is
governed using the 4-step commutation
method to avert the momentary
disconnection of the inductive load
connected at the matrix converter output.[2]
A second order LC filter is involved to
reduce the aberration in the load voltage.
The space vector modulation (SVM)
technique is used to provide the triggering

Fibonacci Series for Hybrid Symmetrical Multilevel Inverter
Topology Using Different PWM Strategies
Jeetu Khan*, Vijay Bhuria, Praveen Bansal Department of Electrical Engineering, Madhav Institute of Technology & Science, Gwalior, India
Abstract
Multilevel inverters are suggested to obtain high superiority output voltage. In this paper, a
new hybrid configuration is proposed, obtained by cascading one four switches H-bridge cell
with a family of multilevel inverters. In addition, by the use of specific sequence for value of
DC sources named Fibonacci series, new topology of proposed inverter is introduced. Main
advantages are that planned inverter has least Peak Inverse Voltage (PIV) than other
conventional multilevel converters in both symmetric and asymmetric modes. Also, this
topology doubles the number of output levels using only one cascaded four switches H-bridge
cell. This paper proposes a 7-level Fibonacci series for new hybrid symmetrical multilevel
inverter. This proposed multilevel inverter topology here is implemented in single-phase with
different pulse width modulation (PWM) techniques, which requires less number of
components, less carrier signals and gate drive circuit as compared to conventional
multilevel inverters. A multicarrier PWM technique is used for multilevel inverter topology to
generate 7-level output voltage. Finally simulation results of a 7-level multi-level inverter
topology are carried out using MATLAB/Simulink R2010a software version.
Keywords: multi-level inverter (MLI); Pulse Width Modulation (PWM) techniques; Peak
Inverse Voltage (PIV) and Fibonacci series
INTRODUCTION
High-power industrial applications of
converters have been revolutionized in the
recent decades by the advent of multilevel
converters.[1]
Lately, multilevel converters
have presented an important development
to reach higher power with increasing
voltage levels.[2]
Also many multilevel
inverter configurations and pulse width
modulation (PWM) techniques are
presented to improve the output voltage
harmonic spectrum.[3–5]
Multilevel inverters can be considered as
voltage synthesizers, where in the output
voltage is synthesized from many discrete
smaller voltage levels. Compared with the
traditional two-level voltage inverter, the
main advantages of the multilevel inverters
are having smaller output voltage step,
lower harmonic components, better
electromagnetic compatibility and lower
switching losses.[2,6–9]
They can also
operate at both fundamental switching
frequency and higher switching
frequencies in accord with the
implementations.[9]
But, the main drawbacks of the multilevel
inverters are the use of larger number of
semiconductors switches and every switch
requires a separate gate driver circuit
therefore increasing the complexity and
size of the overall circuit. From among
voltage source multilevel converters,
cascaded and modular multilevel
