The utilisation of demand side resources is set to increase over the coming years with the advent of advanced metering infrastructure, home area networks and the promotion of increased energy efficiency. Demand side resources ...
Frequency control is essential for the secure and stable operation of a power system. With wind penetration increasing rapidly in many power systems, ensuring continuous power system security is vital. The frequency ...
It is common to operate distributed generators (DGs) at fixed inductive power factors to overcome voltage rise constraints on distribution networks. This approach increases distribution system reactive power demand, which ...
Cascading component failure can cause system-wide blackouts in power systems. Complex system analysis of the long term dynamics suggests that power transmission systems operate near a critical point. Here the effect of ...
In the analysis of time series of blackouts a power
law dependency of blackout size with respect to frequency has
been observed. It has been hypothesized that this behaviour is the
result of the power system operating ...
Distributed Generation (DG) is increasing in penetration on power systems across the world. In rural areas, voltage rise limits the permissible penetration levels of DG. Another increasingly important issue is the impact ...
Increasing penetration of wind power on power
systems worldwide is resulting in the unconventional operation
of base-load generating units. These units which were originally
designed for operation at full output are ...
The growth of wind power as an electrical power generation resource has produced great benefits with reductions in emissions and the supply of zero cost fuel. It also has created
challenges for the operation of power ...
Nonphysically firm wind generation connections (i.e., those to which curtailment can apply) may be necessary for significant wind integration to congested transmission networks. A study of factors influencing this associated ...
With the advent of wind power generation on worldwide power systems, many operators and researchers are analyzing the impacts that higher future amounts may have on system operations. Many of the tools are analyzing longer ...
Frequency stability is the paramount concern for secure and reliable operation of a power system. High wind penetration levels are reported in power systems with high thermal generation, and hence its likely to result high ...
In this paper we introduce the use of force feedback in conjunction with myoelectric control to establish an improved interface for a powered prosthetic limb. The force feedback is delivered through a single-axis exoskeleton ...
Many modern electricity systems are faced with the
challenge of reducing green house gas emissions and dealing with
increasing and more volatile fuel prices. Adequately dealing with
these issues requires the evolution ...
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 implementation of electric vehicles ...
The introduction of distributed generation (DG) onto distribution networks has a significant effect on losses. This effect cannot be characterised as detrimental or beneficial but is dependent on the allocation of DG on ...
Due to rising fossil fuel and electricity prices and the
overall need to reduce carbon emissions, there is a growing
interest in the utilisation of micro-generation amongst
electricity consumers and governments alike. ...
Battery electric vehicles are considered by many to
be part of a series of measures necessary to reduce global carbon
dioxide emissions and dependence on fossil fuel resources. The extent
to which this is possible depends ...
In this paper, the unit commitment and dispatch of a power system with and without a pumped storage unit is examined for increasing levels of installed wind power, from 17% of total energy to 80% of total energy generated ...
Long-term power system planning is beset by a
trade-off between detail and scope: The chosen approach usually lies somewhere between modeling a great many generation
portfolios coarsely and very few in a more detailed ...
