Course on Frequency Control and Inertial
Response of Power Systems with wind Power
Penetration. The frequency of a power system
depends on real power balance:
generation-demand. In the standard operation of
a power system, the frequency is regulated
within strict limits by adjusting the electrical
supply to meet the demand. If the balance
between generation and demand is not reached,
the system frequency will change at a rate
initially determinate by the total system
inertia. The total system inertia comprises the
combined inertia of most of spinning generation
and load connected to the power system. The
contribution of the system inertia of one load
or generator depend if the system frequency
causes change in its rotational speed and, then,
its kinetic energy. Worldwide, electricity
generation from renewable energy is increasing
rapidly; it is especially true in terms of the
increasing of the wind power penetration. This
situation arise some issues regarding the system
frequency control because wind turbines provide
small or even none response to frequency
changes. Power electronically controlled and/or
power electronically connected generators such
as DFIG and FPC wind turbines do not naturally
provide inertia response. However inertia
response can be emulated by adding a
supplementary control signal proportional to the
rate of change of frequency, this is named the
Synthetic or Artificial Inertia. This approach
imposes some challenges about control and
protection systems. The course is designed to
provide a solid understanding of the frequency
control and inertial response of power systems
with wind power penetration. |

Wind Power Development Stalled in Venezuela.
Venezuela could install as much as 1,600 MW
of wind power generation by 2015-20, according
to a key industry source that wished to remain
nameless. He added that the country is making
progress in pursuing three projects that could
add as much as 300 MW in the next couple of
years. Francisco Gonzalez-Longatt, vice
president of Venezuelan Wind Energy Association
(AVeol), says it's too early to provide an
accurate forecast for the country's wind
potential but notes Venezuela's 2,718Km northern
coastal strip has strong wind speeds blowing an
annual average of 8.9 meters per second.
Francisco Gonzalez-Longatt, vice president

says it's too early to provide an accurate
forecast for the country's wind potential but
notes Venezuela's 2,718Km northern coastal strip
has strong wind speeds blowing an annual average
of 8.9 meters per second. "We could fill up the
whole coast with offshore platforms because the
wind speed there is very good," he notes.
However, he adds reliable and sufficient
ocean-depth studies are missing to make such a
task feasible. |

"Wind power could play role in solving
Venezuelan power crisis". Dr Francisco M.
Gonzalez-Longatt was interviewed by the
Business
News America journalist Nathan Crooks of
about the role of wind power integration on
Venezuela. He is optimistic about the future of
wind power integration into Venezuelan power
system. He said "When you look at the economic
studies for any wind farm in any part of the
world, the power is always going to be more
expensive than from conventional sources. But in
the case of Venezuela, you don't have to burn
fuel. That fuel can then be exported at
international prices. So you can't just compare
the local cost of wind power with the local cost
of conventional power. If you take into account
the extra oil you can export, wind power begins
to look a lot more attractive". For complete

Dr Francisco M. González-Longatt has been
interviewed about their views on renewable
energy in Venezuela. On Friday, 9th April
2010, the renowned journalist Andres Rojas
Jiménez of El Nacional newpaper, Venezuela, has
interviewed Dr Francisco M. González-Longatt
about his opinion regarding alternative energy
resources and electricity situation in
Venezuela. Dr Gonzalez-Longatt has been emphatic
on the need to create a culture of saving energy
in the population, and he has agreed the
implementation of new tariff schemes will help
both the subscriber as the electricity companies
in Venezuela. Hourly rates, said Dr Gonzalez-Longatt,
largely aimed at encouraging voluntary savings,
efficiency, and thus to flatten the demand for
electricity. Similarly noted a reduction in the
frequency of Venezuelan interconnected system
operation as a simple technical measure and
energy saving. Finally, Prof. Francis M.
González-Longatt to pointed out the need for
screening and selection of solid resources as a
state policy, which finally allows to use the
valuable resource of garbage as a source for
electricity production. [Download the Article

Preliminary Wind Resource Atlas of Venezuela.
On Wednesday April 7, 2010 was performed with
great success one day meeting titled Wind Energy
Project in Venezuela. Dr
Francisco M.
González-Longatt, lectured about a Preliminary
Wind Resource Atlas in Venezuela.
This Atlas is based on measurements of 2005,
2006 and 2007 years from 37 meteorological
stations distributed over the whole of
Venezuela.
Statistical imputation treatment algorithm based
on a maximum expectation was used for the
completion of the lost data.
A spatial interpolation method was used to
determine the wind resource (speed and power
density -Watt/m2) like treatment necessary to
consider the effect of terrain on the wind
resource.
As a result of this research has determined that
the stations with high power density were the
Choir, Porlamar, Cumana and Güiria, which form
part of northern Venezuela.
Spatial interpolations show the best features of
wind are located in Zulia, Falcón, Nueva Esparta
and Sucre.
Wind speeds in those states exceed Class 3 winds
are defined as acceptable for wind generation,
and even in places like Rio Seco in Falcon state
speeds reach 6.5 m/ s. [Download
