Distribution System Analysis with Wind Generation by Means of Sensitivity Technique

This paper presents a methodology of sensitivity analysis applied in distribution systems with wind generation. The methodology consists of applying a sensitivity technique (ST) in the optimum power flow (FPO) solution, considering the distribution system characteristics. The ST does not require an iterative process of obtaining the solution, resulting in a fast methodology with great precision. Starting with the OPF solution, new operating points are calculated directly after occurring perturbations in the loads and wind generations. The studied networks were composed by wind generation in the form of distributed generation. The proposed methodology was validated through 5-bus and 34-bus radial distribution systems. The results were compared with the FPO solution in order to demonstrate the effectiveness of the methodology.
