Abstract: This paper proposes a grid
interfaced solar photovoltaic power generating
system consisting of photovoltaic cell, DC-DC
boost converter, Inverter, Capacitor bank,
transformer, single phase grid feeder. A reference
grid current are taken from the single phase is
given to microcontroller, which is used to detect
zero crossing and auxiliary power supply to the
microcontroller. Here we interface solar energy
with grid taking frequency into consideration. We
are using solar energy since it is one of the most
renewable forms of energy which is found to be
abundance in all part of the world. During peak
hours voltage fluctuation problems occurs in the
transmission line, at this condition the load get
damaged. To avoid this battery is connected
parallel to the solar panel.

System, Renewable Energy
I. INTRODUCTION
Renewable energy systems such as photovoltaic
power generation, wind power generation and fuel
cells are receiving a huge attention globally. Eco
friendly power generation is the best feature of
renewable energy systems. Renewable energy
systems emit no pollution into the atmosphere when
they generate electricity. However, most power
plants such as thermal power generation and nuclear
power generation plants have produced most of the
power supply. But, Thermal and nuclear plant
establish a danger impacts in the world.. On the other
hand, renewable energy systems are very clean on a
large-scale from the perspective of return of
investment. In this paper, we propose a management
system to maximize the efficiency of a photovoltaic
power system in application's aspect.
The combination of element technologies of
renewable energy with commercial electricity result
in high efficiency and positive results as described
above.
However, while research on the element
technologies have been studied well, studies on
energy management with renewable energy are not
relatively developed. In case of on-grid photovoltaic
systems connected to commercial electricity grids
directly through Inverters like in figure 1, power
consumption can be decreased in buildings or homes,
but there could also be energy loss when power
consumption is very low or electricity price are
cheap, and vice versa.
We are interfacing solar energy with grid. There
are many types of renewable energy such as solar,
wind, tidal etc., In our project we proposes solar
energy since it is convenience for us.
The paper is organized as follows: Section 2
explains the boost converter section. Section 3
discusses the inverter section. Section 4 explains the
transformer section. Microcontroller and grid section
discussed in Section 5,6. In section 7 discusses the
over all block diagram and explanation. Output
and conclusions in Section 8 and 9.
II. BOOST CONVERTER SECTION
A DC-to-DC is an electronic circuit which
converts a one level of voltage value to the other
level voltage values. It is one type of power
converters in power Electronics. DC to DC
converters are important converter in the field of
electrical, and it is used for various electronic
devices. Such electronic devices contain several sub-
circuits, each with its own voltage level requirement
different from that supplied by the battery or an

external supply (sometimes higher or lower than the
supply voltage).
Additionally, the battery voltage declines as its
stored power is drained. Compare than partially
lowered battery, Switched DC to DC converters offer
to increase voltage levels. At the same time saving
space is another advantage, instead of using multiple
batteries to accomplish the same thing.
In this project the converter helps to increase
voltage levels from 12V to 24.6V
Figure 1: Boost Converter
III. INVERTER
In renewable systems (solar cell) the output
is DC.It is modified to Ac by use of inverters. The
output level of AC magnitude is small. For that, we
are used transformer to increase the magnitude
level.
The inverter usage will start from small level (like
computers) to higher level (high voltages direct
current transmissions).
Figure 2: Inverter
Here, the use of inverter is same to convert from
DC to AC. The output of solar section is DC. This
DC quantity is converted into AC. The output of the
AC is interfaced with grid power (AC).
IV. TRANSFORMER
A transformer is an electrical device used to convert
AC power at a certain voltage level to AC power at a
different voltage, but at the same frequency. The
transformer is based on the working principle of
“Faradays Law of Electromagnetic induction”. In this
project, we used only the step down transformer not
the step up transformer. Here we step down a 230V
ac into 12V ac.
The supply is given to the primary of the
transformer. The voltage induced in the secondary
due to induction. In the secondary coil voltage is
related with primary coil voltage with turns ratio. For
example, if the primary coil have 100 turns and c 480
volts and a secondary coil is 25 turns, the secondary
voltage is calculated by using the below relations.
Secondary voltage = (480 volts) * 0.25 = 120 volts

Figure 3: Transformer
Energy losses in transformers are due to a
number of factors: these are copper losses in the coils
themselves due to material resistance, core losses due
to hysteresis eddy current (the reluctance of the
material's magnetic domains to reverse during each
electrical cycle).Step-down transformer form one
phase is taken to give auxiliary supply to
microcontroller and also to detect zero crossing to
synchronize solar frequency with gridfrequency step
up transformer is used to increase the voltage.
Figure 4: Transformer connection with the system
V. MICROCONTROLLER
In this project, the output is to synchronize the
solar output and grid output. It is done by using the
zero crossing method. The output of the
microcontroller section is our required
synchronization result. The comparison procedure is
developed by coding and stored the microcontroller.
The ATmega8L is a low-power CMOS 8-bit
microcontroller is used in this project. A reference
grid current are taken from the single phase is given
to microcontroller, which is used to detect zero
crossing and auxiliary power supply to the
microcontroller.
Figure 5: Microcontroller pin diagram
VI. GRID
Generally grid means interconnected
substations. It is the junction between the two sub
stations. If any one substation voltage value gets
damaged due to some interrupted conditions, it give
the same value without interruption.
Here, the output of solar panel DC is
converted into AC .The output AC is interfaced with
grid. The frequency matching is very important for
solar grid interfacing. This is done by using the
microcontroller.
In this project, 230Volts (AC) normal
supply is considered for grid system.

Voltage from solar panel is stored in a 12V
battery is been given to the DC-DC boost converter.
In the boost converter PTC coil is placed to avoid
over voltage. The heat sink is provided for the
MOSFET to avoid overheating. The driver circuit is
used to switch ON & OFF the MOSFET. The output
of the boost converter is 24.6V. The output of the
boost converter is given to the Inverter through the
capacitor bank. Microcontroller is used to
synchronize solar frequency with grid frequency.
Step-down transformer 230V to 12V is given to
microcontroller for auxiliary power supply and for
the detection of zero crossing. Output of the inverter
is given to Step-up transformer to a manual breaker.
This step-up transformer gives the output of 230V
which is fed to the grid.
The overall developed circuit model is shown in the
figure (6). The Expected synchronized output shown
in the figure (7) also un synchronized waveform is
shown in figure (8).The Digital Storage Oscilloscope
was used to show the output results.

  • 1. ISSN: 2278 – 7798 International Journal of Science, Engineering and Technology Research (IJSETR) Volume 2, Issue 7, July 2013 1526 www.ijsetr.org Abstract: This paper proposes a grid interfaced solar photovoltaic power generating system consisting of photovoltaic cell, DC-DC boost converter, Inverter, Capacitor bank, transformer, single phase grid feeder. A reference grid current are taken from the single phase is given to microcontroller, which is used to detect zero crossing and auxiliary power supply to the microcontroller. Here we interface solar energy with grid taking frequency into consideration. We are using solar energy since it is one of the most renewable forms of energy which is found to be abundance in all part of the world. During peak hours voltage fluctuation problems occurs in the transmission line, at this condition the load get damaged. To avoid this battery is connected parallel to the solar panel. Key words: Energy Efficiency, Photovoltaic System, Renewable Energy I. INTRODUCTION Renewable energy systems such as photovoltaic power generation, wind power generation and fuel cells are receiving a huge attention globally. Eco friendly power generation is the best feature of renewable energy systems. Renewable energy systems emit no pollution into the atmosphere when they generate electricity. However, most power plants such as thermal power generation and nuclear power generation plants have produced most of the power supply. But, Thermal and nuclear plant establish a danger impacts in the world.. On the other hand, renewable energy systems are very clean on a large-scale from the perspective of return of investment. In this paper, we propose a management system to maximize the efficiency of a photovoltaic power system in application's aspect. The combination of element technologies of renewable energy with commercial electricity result in high efficiency and positive results as described above. However, while research on the element technologies have been studied well, studies on energy management with renewable energy are not relatively developed. In case of on-grid photovoltaic systems connected to commercial electricity grids directly through Inverters like in figure 1, power consumption can be decreased in buildings or homes, but there could also be energy loss when power consumption is very low or electricity price are cheap, and vice versa. We are interfacing solar energy with grid. There are many types of renewable energy such as solar, wind, tidal etc., In our project we proposes solar energy since it is convenience for us. The paper is organized as follows: Section 2 explains the boost converter section. Section 3 discusses the inverter section. Section 4 explains the transformer section. Microcontroller and grid section discussed in Section 5,6. In section 7 discusses the over all block diagram and explanation. Output and conclusions in Section 8 and 9. II. BOOST CONVERTER SECTION A DC-to-DC is an electronic circuit which converts a one level of voltage value to the other level voltage values. It is one type of power converters in power Electronics. DC to DC converters are important converter in the field of electrical, and it is used for various electronic devices. Such electronic devices contain several sub- circuits, each with its own voltage level requirement different from that supplied by the battery or an DESIGN AND IMPLEMENTATION OF SOLAR ENERGY WITH GRID INTERFACING A.MANIKANDAN GOWTHAM, V.SEENIVASAGAN, P.MANIKANDAN, P.MANIKANDAN, Student, student, Asst.Prof. HOD Department of Electrical and Electronics Engineering, Sree Sowdambika College of Engineering, Aruppukottai-626101, Tamil nadu, India.

Additionally, the battery voltage declines as its stored power is drained. Compare than partially lowered battery, Switched DC to DC converters offer to increase voltage levels. At the same time saving space is another advantage, instead of using multiple batteries to accomplish the same thing. In this project the converter helps to increase voltage levels from 12V to 24.6V Figure 1: Boost Converter III. INVERTER In renewable systems (solar cell) the output is DC.It is modified to Ac by use of inverters. The output level of AC magnitude is small. For that, we are used transformer to increase the magnitude level. The inverter usage will start from small level (like computers) to higher level (high voltages direct current transmissions). Figure 2: Inverter Here, the use of inverter is same to convert from DC to AC. The output of solar section is DC. This DC quantity is converted into AC. The output of the AC is interfaced with grid power (AC). IV. TRANSFORMER A transformer is an electrical device used to convert AC power at a certain voltage level to AC power at a different voltage, but at the same frequency. The transformer is based on the working principle of “Faradays Law of Electromagnetic induction”. In this project, we used only the step down transformer not the step up transformer. Here we step down a 230V ac into 12V ac. The supply is given to the primary of the transformer. The voltage induced in the secondary due to induction. In the secondary coil voltage is related with primary coil voltage with turns ratio. For example, if the primary coil have 100 turns and c 480 volts and a secondary coil is 25 turns, the secondary voltage is calculated by using the below relations. Secondary voltage = (480 volts) * 0.25 = 120 volts

Figure 4: Transformer connection with the system V. MICROCONTROLLER In this project, the output is to synchronize the solar output and grid output. It is done by using the zero crossing method. The output of the microcontroller section is our required synchronization result. The comparison procedure is developed by coding and stored the microcontroller. The ATmega8L is a low-power CMOS 8-bit microcontroller is used in this project. A reference grid current are taken from the single phase is given to microcontroller, which is used to detect zero crossing and auxiliary power supply to the microcontroller. Figure 5: Microcontroller pin diagram VI. GRID Generally grid means interconnected substations. It is the junction between the two sub stations. If any one substation voltage value gets damaged due to some interrupted conditions, it give the same value without interruption. Here, the output of solar panel DC is converted into AC .The output AC is interfaced with grid. The frequency matching is very important for solar grid interfacing. This is done by using the microcontroller. In this project, 230Volts (AC) normal supply is considered for grid system. VII. OVERALL BLOCK DIAGRAM
