THESIS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY The impact of wind power variability on the least-cost dispatch of units in the electricity generation system
نویسنده
چکیده
This thesis investigates the dynamics of electricity generation systems that involve high levels of wind power. Methods to account for wind power variability in electricity-dispatch models are explored, and the impact of wind power variability on the optimal output of the generation units, so as to meet the system load with the lowest possible cost (economic dispatch), is analyzed for several systems, for both regional and European cases. Systems that lack active variation management, as well as systems with variation management through storage, charging of plug-in hybrid electric vehicles, and trade with the hydropower-rich Nordic countries, are investigated. The work considers systems in which wind power supplies between 20 % and 40 % of the electricity demand on an

متن کاملA Multi-Objective Economic Load Dispatch Considering Accessibility of Wind Power with Here-And-Now Approach
The major problem of wind turbines is the great variability of wind power production. The dynamic change of the wind speed returns the quantity of the power injected to networks. Therefore, wind–thermal generation scheduling problem plays a key role to implement clean power producers in a competitive environment. In deregulated power systems, the scheduling problem has various objectives than i...

The significant penetration rate of wind turbines in power systems made some challenges in the operation of the systems such as large-scale power fluctuations induced by wind farms. Gas-fired plants with fast starting ability and high ramping can better handle natural uncertainties of wind power compared to other traditional plants. Therefore, the integration of electrical and natural gas syste...
