Probabilistic Optimal Active and Reactive Power Dispatch including Load and Wind Uncertainties considering Correlation

International Transactions on Electrical Energy Systems, Volume 2023, Issue 1, 2023., 2023
The increased integration of renewable energies (REs) raised the uncertainties of power systems and has changed the approach to dealing with power system challenges. Hence, the uncertain nature of all the power system variables needs to be considered while dealing with the optimal planning and operation of modern power systems.
