ADVANCES IN WIND POWER

ADVNCES IN WIND POWER

Today’s wind energy industry is at a crossroads. Global economic instability has threatened
or eliminated many financial incentives that have been important to the development of
specific markets. Such economic sponsorship of energy generation is not unique to
renewables; fossil based sources are also subsidized in many different countries. However,
for a technology like wind energy whose markets are still developing, incentives can be
critical for industry growth. Industry proponents have decreed that long-term energy policy
that survives financial swings and changes in government is what is needed to provide the
stability that market investors seek. While this may be the case, in the mean time, the
pressure is on wind industry designers, manufacturers, and operators to seek the most
effectual measures for wind power production.

Like the wind itself, the industry operates on large and small scales. While large commercial
wind has traditionally received the most coverage in the literature and the media, small
wind has recently established itself as a major player in distributed energy systems. This
will become increasingly important as micro grids rapidly find their place in both the
developed and developing worlds. In urban and isolated rural settings, small wind is
growing rapidly. It is important to emphasize this multi-scale resilience that wind
generation provides as an energy solution. The broad range of scales within wind energy is
only surpassed by the expansive scope of technologies that cover the spectrum from
resource assessment to grid integration. Specialized sub-topics continue to emerge that
provide focus for improving critical links in the wind chain. This sort of specificity can be
vital for isolating technical elements from the complexity of interconnected wind energy
systems. A brief list of emerging specific interest fields include aerodynamic interaction of
wind turbine groups, computational modeling of complex composite blades, magnetic
speed multiplying converters, generator controls optimized for small wind, disturbance
tolerant generators, micro and smart grid integration.
This text details topics fundamental to the efficient operation of modern commercial farms
and highlights advanced research that will enable next-generation wind energy
technologies. The book is organized into three sections, Inflow and Wake Influences on
Turbine Performance, Turbine Structural Response, and Power Conversion, Control and
Integration. In addition to fundamental concepts, the reader will be exposed to
comprehensive treatments of topics like wake dynamics, analysis of complex turbine blades,
and power electronics in small-scale wind turbine systems.
