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 ...
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 ...
Certain developments in the electricity sector may result in suboptimal operation of base-load generating units in countries worldwide. Despite the fact they were not designed to operate in a flexible manner, increasing ...
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 ...
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 integration of variable generation continues to grow rapidly in power systems globally, system planners are seeking new tools to understand the role of variable output generators and the challenges experienced with their ...
The concept of capacity credit is widely used to quantify the contribution of renewable
technologies to securing demand. This may be quantified in a number of ways; this paper
recommends the use of Effective Load ...
Rising wind generation penetrations and the distinctive inertial characteristics of associated turbine technology will impact system frequency control. While wind production will displace conventional synchronous ...
Prudent use of existing transmission capacity could be achieved by an optimal allocation of wind capacity to distinct transmission nodes. The statistical interdependency of geographically separate wind sites and the ...
