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 ...
The capacity value of wind power indicates the extent to which wind power contributes to the generation system adequacy of a power system. The related data requirements may be subject to difficulties due to the temporal ...
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 ...
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 ...
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 ...
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 ...
As power systems evolve to incorporate greater
penetrations of variable renewables, the demand for flexibility
within the system is increased. Combined-cycle gas turbines are
traditionally considered as relatively ...
With increasing levels of variable renewable energy, there is a growing need to study its impacts on power system operation. Variable generation (VG) is variable and uncertain at multiple timescales, and it is important ...
As power systems evolve to incorporate greater
penetrations of variable renewables, the demand for flexibility
within the system is increased. Combined Cycle Gas Turbines
(CCGTs) are traditionally considered as inflexible ...
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. ...
