The main aim of this paper is to investigate the market penetration and share of different wind turbine concepts during the years 1998-2002, a period when the increase in the wind power capacity is starting to mark an abrupt evolution (more than two GW per year). A detailed overview is performed based on suppliers market data and concept evaluation for each individual wind turbine type sold by ...

This research investigates the effect of wind penetration on the frequency response demonstrated by the NPCC system. The frequency response of the system is entirely dependent on the regulating unit models that were also developed as part of this research. The simulations run on the NPCC system with wind penetration suggest that the wind turbine generator model needs to be developed further, an...

Modern day power systems are divided into various areas. The transmission lines that connect an area to its neighboring area are called tie-lines sharing power between two areas. Automatic Generation Control (AGC) as the name signifies it regulates the power flow between different areas while holding the frequency constant. Frequency control as a major function of automatic generation control i...

The paper presents an electromechanical auto synchronized wind energy conversion system (WECS) for larger penetration of renewable energy sources (RES) in the rural electrification systems. The architecture of the WECS uses two stator windings at power frequency which provides harvesting of power to flow from WECS to load and to grid side when the generated power is in access. Asymmetrical six ...

Many isolated small power systems are powered by diesel generators, which results in greater operating costs than interconnected large grids. It is therefore desirable to integrate renewable energy sources such as wind power into these small grids. However, due to the fluctuating power generation from renewable energy sources, frequency deviations of power systems become problematic. Distribute...

Power curve measurements provide a conventional and effective means of assessing the performance of a wind turbine, both commercially and technically. Increasingly high wind penetration in power systems and offshore accessibility issues make it even more important to monitor the condition and performance of wind turbines based on timely and accurate wind speed and power measurements. Power curv...

This paper demonstrates the use of model-based predictive control for energy storage systems to improve the dispatchability of wind power plants. Large-scale wind penetration increases the variability of power flow on the grid, thus increasing reserve requirements. Large energy storage systems collocated with wind farms can improve dispatchability of the wind plant by storing energy during gene...

Wind power generation has indicated an exponential increase during last two decades and existing transmission network infrastructure is increasingly becoming inadequate to transmit remotely generated wind power to load centres in the network. The dynamic line rating (DLR) is one of the viable solutions to improve the transmission line ampacity during high wind penetration without investing on a...

Egypt is moving towards smart grid infrastructures to enable efficient bidirectional power supply with reduced carbon footprint. The target smart grid will feature distributed energy generation with renewable energy systems. With the improvement of wind power technology in Egypt, increase of wind power capacity, the impact of wind power on the grid has become an important research topic as well...

We consider the control of a wind power plant, possibly consisting of many individual wind turbines. The goal is to maximize the energy delivered to the power grid under very strict grid requirements to power quality. We define an extremely low power output gradient and demonstrate how decentralized energy storage in the turbines’ inertia combined with a central storage unit or deferrable consu...
