An inverter is an electric apparatus that changes direct current (DC) to alternating current (AC). It is not the same thing as an alternator, which converts mechanical energy(e.g. movement) into alternating current.
Direct current is created by devices such as batteries and solar panels. When connected, an inverter allows these devices to provide electric power for small household devices. The inverter does this through a complex process of electrical adjustment. From this process, AC electric power is produced. This form of electricity can be used to power an electric light, a microwave oven, or some other electric machine.
In microgrid, if fault occurs or any other contingency happens, then the problems would be created which are related to power flow, also there are various protection schemes are used for minimize or eliminate these problems.
Voltage control is used for reactive power balance and P-f control is used for active power control.
Various protection schemes such as, over current protection, differential protection scheme, zoning of network in adaptive protection scheme are used in microgrid system .

Perspective of biodiesel & solar pv as a combined renewable energy system...eSAT Journals
Abstract The power generation method is more over traditional and supply of electricity is decentralized which is considered a single line technology based on limited supply devoid of considering rural consumer’s point of view. The main aspect of this paper is to propose the best possible outcome as a combined power system for rural electrification from a combination of renewable resources to complete the electrical demands in a consistent manner of an off grid remote village Bakri, in the district of Jhenaidah, Bangladesh. Renewable energy resources namely solar photovoltaic cell and bio-diesel generators are considered here. The paper estimates the residential demand in the pre HOMER analysis. Using simulation software named HOMER scrutinizes the maximum outcome. It also clarifies that our proposed combine power system is cost effective techno-economically & environmentally sound and last but not the least sustainable. Here HOMER observes a number of simulations and gives us a set of systems for rural electrification requirement of 147 kWh/d and 10kW peak load. Keywords: Rural electrification, Combined Power System, HOMER, Bio-fuel generator, Solar PV.

Design of a hybrid power system for a low dc voltage distribution system suit...Itai Hamunakwadi
Abstract—This paper focuses on the design of a hybrid power
system based on renewable energy sources for Low Voltage
Distribution system suitable for remote areas. Rural
electrification has been a challenging issue for many third world
countries. The available national voltage distribution systems are
only limited to areas with good road networks. Consequently, this
means rural and remote areas with poor road networks are
isolated from the national grid. Research is to be conducted so as
to design a feasible islanded power system that can furnish
adequate power to such areas.
Design and Modeling of Grid Connected Hybrid Renewable Energy Power GenerationIJERA Editor
This paper proposes a design and modeling of grid connected hybrid renewable energy power generation. The
energy system having a photo voltaic (PV) panel, Srg wind turbine and fuel cell (sofc) for continuous power
flow management. Fuel cells (storage & generating) are added to ensure uninterrupted power supply due to the
discontinuous nature of solar and wind resources. Renewable energy generated during times of plenty can be
stored for use during periods when sufficient electricity is not available. But storing this energy is a difficult
task: batteries and similar technologies perform well over short timescales, but over periods of weeks or months
a different approach is necessary. Energy storage in the form of hydrogen is one such possibility: excess
electricity is fed into an electrolyser to split water into its constituent parts, oxygen and hydrogen. The hydrogen
is then used in fuel cells to produce electricity when needed which will overcome the problem of storage. This
work is mainly concentrated on the design, analysis and modelling of Fuel cells and Analysis and modelling of
Switched Reluctance Generator (SRG) in the application of Wind Energy Generation and pv cell. Also an
effective approach is proposed in this thesis to ensure renewable energy diversity and effective utilization. The
pv cell, wind and fuel cell renewable energy system is digitally simulated using the MATLAB/SIMULINK
software environment and fully validated for efficient energy utilizations and enhanced interface power quality
under different operating conditions and load excursions
Performance analysis of wind turbine as a distributed generation unit in dist...ijcsit
In this paper, the performance analysis of wind turbine as a distributed generation unit is presented. In this
study a model of wind power is driven by an induction machine. Wind power that is distributed generation
is capable of supplying power to ac power distribution network. Wind power generation system is modeled
and simulated using Matlab Simulink software such that it can be suitable for modeling some kind of
induction generator configurations. To analyze more deeply the performance of the wind turbine system,
both normal and fault conditions scenarios have been applied. Simulation results prove the excellent
performance of the wind power unit under normal and fault conditions in the power distribution system.

Role of power electronics in renewable and non renewable sources
1. THE ROLE OF POWER ELECTRONICS
IN RENEWABLE AND NON
RENEWABLE SOURCES

2. According to International Energy Agency (IEA) data
from 1990 to 2008, the average energy use per person
increased 10% while world population increased 27%.
And as of 2010, about 16% of global final energy
consumption comes from renewable but at the same
time the fossil fuels (liquid, coal and natural gas) have
been the primary energy source for the present day
world which is of non-renewable energy system. So the
renewable as well as non-renewable energy system both
is important for human development.
INTRODUCTION
6. 1.Wind energy system
Wind power is the conversion of wind energy in to useful form of
energy i.e electrical energy. the diagram shows conversion wind
energy in to electrical energy
. Between the grid and the generator a power converter can be
inserted. The electrical output can either be AC or DC. In the last
case a power converter will be used as interface to the grid.
High frequency direct AC-AC conversion has also been proposed
as coupling of wind energy conversion systems to the grid.
7. 2.Photovoltaic system
Photovoltaic energy systems consist of arrays of solar cells.
By the figure, PV modules are connected in series and/or in parallel
and then connected to a centralized DC/AC converter.
8. 3.WAVE ENERGY
• Wave energy is the transport of
energy by ocean surface waves,
and the capture of that energy
to do useful work – for
example, electricity generation,
water desalination, or the
pumping of water (into
reservoirs)
• The primary advantage of
most power electronic
coupling is the possibility to
integrate energy storage
units such as super
capacitors, or
superconducting
9. 4.INTERNAL COMBUSTION SYSTEM
• The internal combustion
engine system firstly
converts chemical energy
into mechanical energy
which in turn spins a shaft to
convert the mechanical
energy into electrical energy.
• The energy can be converted
in DC as well as AC With
power electronics as
interface, the combined
efficiency of engine-
generator can be optimized
and provide the flexibility of
adding energy storage
systems
10. 5.MICRO TURBINE
• Micro turbine system has
shafts spinning at up to120.000
rpm driving a high speed
generator. The high frequency
output from the generator is
first rectified and then
converted to grid frequency AC
power.
• Then a DC-AC inverter is used
to build up three phase
voltages at the frequency of the
grid.
Typical power electronic coupling for a micro
turbine system
11. The microturbine generator feeds three phase power into a
rectifier and the DC is then fed into a high frequency single
phase inverter so that a compact high frequency transformer can
be used. The secondary of the transformer feeds an AC- AC
converter that takes the single phase high frequency voltage to
produce a three phase voltage
For High frequency AC link coupling for a
microturbine system
12. 6.FUEL CELLS
• These are electrochemical
devices that produce electricity
without any intermediate
power conversion stage. The
advantage is the energy density
that is nearly 10 times that of a
battery. Fuel cells like PV
systems produce DC power
13. POWER ELECTRONICS COSTS AND OTHER
COSTS FOR DER’s SYSTEMS
Fig: Power electronics costs compared to total capital costs for distributed
energy systems
14. CONCULSION;
The unique advantages of using power electronic couplings have
been discussed throughout the paper and can be summerised in
the following features:
- Flexibility to integrate energy storage units in the
- Maximum power point tracking for PV and wind energy
systems,
- Dispatching capabilities with energy storage units,
- Improved efficiency,
- Variable speed operation ability allowing for fuel usage
optimisation.
In order to make possible all the potentialities mentioned in the
paper, intensive research and development in the power
electronics technology is strongly needed.
