This paper summarises some of the main impacts of
large amounts of wind power installed in the island of Ireland.
Using results from various studies performed on this system,
it is shown that wind power will impact on ...
Advances in the development of electric vehicles,
along with policy incentives will see a wider uptake of this
technology in the transport sector in future years. However, the
widespread adoption of electric vehicles ...
The distributed generation (DG) plant mix connected to any network section has a considerable impact on the total amount of DG energy exported and on the amount of losses
incurred on the network. A new method for the ...
Many countries have declared future renewable
energy penetration targets. Wind power connection to power systems is delayed by limited transmission system capacity as attractive wind sites are often located in weakly ...
High penetrations of wind power on distribution networks
are causing voltage rise on many networks. This voltage
rise is limiting the permissible penetration levels of wind.
Numerous active control schemes have been ...
Renewable electrical energy grid connection is
hampered by transmission capacity limitations and public
opposition to new transmission development. This paper
presents a methodology to find the optimal positions on ...
This paper investigates the just-noticeable-difference (JND) for natural frequency of virtual second order dynamic systems. Using
a one degree-of-freedom haptic device, visual and/or haptic sensory feedback were presented ...
The penetration of Distributed Generation (DG) is increasing on distribution networks
across the world. Non-firm access to the network is now being proposed as a cost effective way to facilitate DG. However, concerns remain ...
With wind power penetration increasing in many systems worldwide, operational issues are beginning to emerge due to the uncertain nature of wind power. One of these issues is
the provision of reserve for system security. ...
Throughout the world significant development is being encouraged in wind energy for electricity generation. A complete cost and benefit analysis has been conducted in this paper on grid connected wind generation. It takes ...
Developments in the electricity sector such as the integration of increasing levels of renewable power, mainly wind, and the deregulation of electricity markets have resulted in some unconventional operation of base-load ...
As the penetration of variable renewable generation increases in power systems worldwide, planning for the effects of variability will become more important. Traditional capacity adequacy planning techniques have been ...
As wind power penetration grows, the amount of reserve needed on the system also grows, due to the increases in the uncertainty of wind power, which grows larger as forecast horizon increases. By scheduling the system more ...
This paper explores the relationship between wind generation, particularly the control of reactive power from variable speed wind turbine generators, and the rotor angle stability of the conventional synchronous generators ...
Capacity credits are widely used to quantify the
ability of different generating technologies to support demand.
Most practical capacity credit calculations are based on detailed
risk modelling, however a wide range of ...
This paper examines the small-signal stability impacts of high penetrations of doubly-fed induction generator (DFIG) wind turbines on power systems. It provides a basic overview of small-signal stability concepts and then ...
As wind generation begins to contribute significantly to power systems, the need arises to assess the impact of this new source of variable generation on the stability of the system. This work provides a detailed methodology ...
Advances in the development of electric vehicles, along with policy incentives, will see a wider uptake of this technology in the transport sector in future years. However,
large penetrations of EVs could lead to adverse ...
This paper outlines how to economically and reliably operate a power system with high levels of renewable generation which are stochastic in nature. It outlines the challenges for system operators, and suggests tools and ...
As wind is a low capacity factor source of power generation, a non-physically-firm connection strategy is key to its cost-effective and timely integration to presently constrained transmission networks. This paper therefore ...
