ABSTRACT
This paper presents the realistic optimization model for wind farm (WF) design. The investigated WF is located in the southern region of Turkey and consists of 10 WTs. In this modeling process, the real wind measurement data, the experimental power curve of WT, variable thrust coefficient, and the real WT characteristic features are taken into account. Also, the wake effect calculations are realized considering the wind direction, topographic effect, and roughness. Wind Atlas Analysis and Application Program (WAsP) is used in calculating WF annual energy production (AEP) and verifies the results of the WF optimization model. ABC algorithm is used in the solution of the developed model. Optimal WT coordinates are determined. The real AEP value of the existing WF is 51.570 GWh. In the WAsP software, the AEP value of the existing WF is found to be 50.665 GWh. With the solution of the developed model, the AEP value of WF is increased to 53.454 GWh. The WTs are positioned on determined coordinates in the WAsP software. The AEP value is found to be 53.542 GWh. As a result, the AEP of WF is increased by 5.68%. The AEP of WTs has been increased except for one WT.
