Unit Commitment and Economic Load Dispatch in the Presence of Wind Turbines

Due to the significant growth of load in the power industry as well as the high penetration of wind turbines (WTs) in power systems, the issue of unit generation (UC) planning has become a critical issue. UC determines the problem of planning the production of units, the time when units are turned on and off, and how to distribute the load between the units that are turned on so that the cost is minimized; Therefore, the main focus of this article includes two scenarios that examine the production planning of units with different constraints, including the slope rate and the production prohibited area in the presence and absence of WTs; Therefore, at first, the production planning of the units is done by considering the load of future hours, which increases the reliability of the planning and also minimizes the costs. In the second part, a method for planning the production of units is presented, in this method, the minimum shutdown time of the units is also included in the objective function, in fact, the start-up costs are considered hourly. This proposed method changes the production planning pattern so that the costs are reduced. Finally, the implementation of the problem is done in two scenarios considering wind turbines and the absence of wind turbines.
