This document discusses how combined heat and power with spinning reserve (CHP-SR) can benefit multiple parties by balancing intermittent wind power. CHP-SR involves an electrically oversized thermally matched CHP system that normally operates at reduced power output. It can balance high and low wind power periods more efficiently than a standalone gas turbine by recycling waste heat. Economic analysis shows CHP-SR lowers operating costs for an ethanol plant compared to its boiler, and provides cheaper power than a utility's coal plant or a gas turbine balancing wind. CHP-SR benefits include reduced steam costs for the ethanol plant, reliable power for the grid, and help for utilities to address emissions regulations while retaining customers.

Hybrid power generation by and solar –windUday Wankar
With the development of industry and
agriculture, a great amount of energy such as coal, oil
and gas has been consumed in the world. Extensive
use of these fossil energies deteriorates a series of
problems like energy crisis, environmental pollution
and so on. Everybody knows that the fossil energy
reserves are finite, some day it will be exhausted.
It is possible that the world will face a
global energy crisis due to a decline in the
availability of cheap oil and recommendations to a
decreasing dependency on fossil fuel. This has led to
increasing interest in alternate power/fuel research
such as fuel cell technology, hydrogen fuel, biodiesel,
Karrick process, solar energy, geothermal energy,
tidal energy and wind. Today, solar energy and wind
energy have significantly alternated fossil fuel with
big ecological problems.
With the development of the science and
technology, power generation using solar energy and
wind power is gradually known by more and more
people. And it is widespread used in many developed
countries. The merits of the solar and wind power
generation are very obvious-infinite and nonpolluting.
The raw materials of the solar and wind
power generation derived from nature, and wind
power generation can work twenty-four hours a day,
solar power generation only works by daylight. In
addition, this kind of power generation has no
exhaust emission and there is no influence to the
nature. But it also has some shortcomings. Because
of the imperfect of the technology, equipment of the
solar and wind power generation is very expensive.
By far, it cannot be widely used.
In addition, solar and wind power
generation system affected by the changing of the
weather very much, so it has obvious defects in
reliability compared with fossil fuel, and it is difficult
to make it fit for practical use the lack of economical
efficiency .Because of these problems it needs to
increase the reliability of energy supply by

1) Net metering policies allow excess power generated to be exported to the grid or paid for by electricity providers.
2) Rooftop solar PV plants are now directly connected to supply mains without batteries, reducing costs and maintenance.
3) Payback periods of less than 5 years are possible due to reduced costs and electricity bill savings over the plant's 25-year lifespan.
This document proposes developing offshore wind farms in the Persian Gulf, Oman Sea, and Caspian Sea based on an analysis of wind data from locations in those areas. It finds that the Persian Gulf is strongly recommended for offshore wind farms due to minimum wind speed requirements being met. The Oman Sea needs further investigation as wind speeds were slightly above minimum requirements. The Caspian Sea is not recommended due to low wind speeds below minimum requirements and high installation costs. It provides an overview of offshore wind farm components and engineering aspects like tower design and relationship between wind speed and power extraction.
IRJET- Vortex Bledless Wind Turbine “A New Approach to More Efficient Wind En...IRJET Journal
This document describes a new type of bladeless wind turbine called a vortex wind turbine. It utilizes vorticity, or eddies created by wind passing a structure, to cause the turbine mast to vibrate and generate energy without blades. This design aims to increase efficiency over conventional wind turbines by reducing costs, requiring less space for installation, and having fewer parts to maintain. It works by using wind flow and pressure to induce vibrations in the turbine mast, which are then converted to energy via a crankshaft and alternator. The design aims to make wind energy production cheaper and allow turbines to be placed in more locations. Testing shows the vortex turbine can generate electricity at 40% lower cost than conventional designs and capture 30%

IRJET- Optimized Blade Replacement Solution in Wind Turbine using Craneless T...IRJET Journal
This document discusses an optimized blade replacement solution for wind turbines using craneless technology. It proposes a cost-cutting system for removing and reinstalling turbine blades without the need for large cranes. The system uses pulleys and tackle arrangement principles to lift and lower the blades. A receptacle holds the blade during lifting/lowering. Load bearing and holding mechanisms support and carry the blade vertically. This craneless solution aims to reduce costs and increase accessibility compared to conventional crane-based blade replacement methods.
This feasibility study examines using a vertical axis wind turbine and battery bank system to charge an electric vehicle (Nissan Leaf) at a domestic dwelling in Ireland. The vertical axis turbine, while less efficient than a horizontal axis turbine, is suitable for the site's turbulent winds and has lower construction costs. A 10kW vertical axis turbine could generate enough electricity to charge the Leaf if wind speeds average 9m/s for 7 hours daily. The system would cost around €34,000 but have a 10-11 year payback period through savings on gasoline compared to a Toyota Corolla. As electricity and fuel prices continue rising, the payback period will decrease, making domestic wind power an economically viable option for electric vehicle charging.

TeleE-site Case Study
This E-site case study is based on information from our Renewable Energy site solution in
Africa.
A vast amount of data and performance statistics has been derived from the real-time intelligent
control and management system, Diriflex® which is part of the E-site®. Presented below are the
main conclusions from a six month measuring period on a trial site with an average total power
requirement of 1.4 kW.
95 % Diesel Reduction
As shown below, the diesel generator has run only 250 hours in six months, which is 6 % of the
total operating hours. Assuming that the average wind will remain at the same level for the next
six months, the total diesel consumption will be less than 600 liters per year. Compared to a
diesel driven site consuming 2 liters/hour, this would mean a yearly diesel saving of about 16
700 liters, adding up to at a 95% diesel reduction.

OPEX reduction
Diriflex® allows for remote site operation, Genset 6%
thus considerably reducing the need for site Renewabl
visits. Together with the limited diesel genset es
run hours, 250 hours during the 4 100 hour
measuring period, this means that the need
for fuelling and maintenance visits to site is
reduced to once annually(!). With off-grid
Renewable
sites, like the one in this case study, being 94%
very difficult and time-consuming to reach,
reducing the number of site visits has reduced
OPEX substantially

One yearly visit resulting in substantial OPEX
reduction. The average wind speed during the whole
period was 5.3 m/s at the wind turbine. This
corresponds to average wind speed of 3.8 m/s at 10
metres. These figures are derived from wind speed
measurements on site with adjustments for the actual
height of the wind turbine, which in this case is 60
metres. Note that the 5,5kW wind turbine is placed on
top of the telecom tower, which is a unique feature of
the E-site® compared to other renewable site
solutions.

The chart above shows that in the first three months wind
conditions were very good with an average wind speed of 7.4
m/s at the wind turbine. This corresponds to 5.3 m/s at 10
metres. During this period wind power catered for 86% of the
total consumption. Solar power complemented with 11 % of
the site’s energy need. An important fact is that the Diriflex®
never started the diesel generator during the first two montIn
the seasonal low wind period, November to January, the
average wind speed at the wind turbine was 3.3 m/s, which
corresponds to 2.3 m/s at 10 metres. Even with this low wind
speed the wind power contributed with 24% of the total power
consumption and solar power complemented with 27%.

Conclusions
During the six month measuring period the site has performed with excellent results. The diesel
generator did not start at all in the first two months and compared to a traditional diesel driven
site, diesel consumption has been reduced by staggering 95 %. Based on an integrated renewable
site solution where our technology know-how allows for the wind turbine to be placed at the top
of the tower or mast, the Diriflex control system has demonstrated its efficiency and superiority
in reducing site OPEX. Furthermore, by reducing the maintenance and fuel visits to once per
year, not only OPEX savings from the diesel reduction, but also the savings from avoiding
visiting sites in far away rural areas site will be considerable.
