Economic Load Dispatch Constrained by Wind Power Availability: A Here-and-Now Approach

A load dispatch model is developed for the system consisting of both thermal generators and wind turbines. The probability of stochastic wind power is included in the model as a constraint. This strategy, referred to as the here-and-now approach, avoids the probabilistic infeasibility appearing in conventional models. It is shown that, based on the presented model, the impacts of stochastic wind speed on the generated power can be readily assessed.
