Increasing the penetration of variable wind generation in power systems has created some new challenges in the power system operation. In such a situation, the inclusion of flexible resources which have the potential of facilitating wind power integration is necessary. Demand response (DR) programs and emerging utility-scale energy storages (ESs) are known as two powerful flexible tools that ca...

The increasing wind power penetration in power systems represents a techno-economic challenge for power producers and system operators. Due to the variability and uncertainty of wind power, system operators require new solutions in order to increase the controllability of wind farm output. On the other hand, producers that include wind farms in their portfolio need to find new ways to boost the...

The renewable energy sources have increased significantly due to environmental issues and fossil fuels elevated cost. Integration of renewable energy sources to utility grid depends on the scale of power generation. Large scale power generations are connected to transmission systems where as small scale distributed power generation is connected to distribution systems. There are certain challen...

Interfacing converters utilized in connecting energy storage systems like ultra capacitors and battery banks to wind generation systems introduce additional cost and power losses. This paper thus presents an immediate integration theme for ultra capacitors utilized in mitigating short-run power fluctuations in wind generation systems. This theme uses a dual electrical converter topology for eac...

Synthetic Aperture Radar (SAR) is a useful and efficient tool for providing high-resolution images from sea surface wind fields. Wind field analysis based on SAR image descriptors makes the estimation of wind direction and speed possible. This is very useful for applications and Studies such as oil spills, waves, ocean circulation, marine meteorology and the coupling of oceanic and atmospheric ...

In this paper a procedure for the probabilistic treatment of irradiance and wind meteorological data is reported in order to evaluate the energy potential of a given site as well as the generation of electricity from photovoltaic systems (PVSs) and wind systems (WECSs). In particular the aim of the proposed analysis of recorded meteorological data is twofold: first of all to check if the real p...

Improving performance of wind turbines through effective control strategies to reduce the power generation cost is highly desired by the wind industry. The majority of the literature on performance of wind turbines has focused on models derived from principles versed in physics. Physics-based models are usually complex and not accurate due to the fact that wind turbines involve mechanical, elec...
