Resumo

This work is focused in analyzing the static voltage stability of great power systems considering a parallel processing approach. The analysis is based on determining the critical power point will lead to the system voltage collapse. In this sense, the Continuation Power Flow (CPF) is applied to Transmission Systems and to the Distribution Networks, considering the insertion of Wind Energy Conversion Systems (WECS), the Cespedes Method is used. To these simulation processes, a parallel computing technology that allows its execution in different processing units simultaneously is proposed, reducing the total execution time. So, the Graphics Processing Units (GPU) is applied to the intensive computational calculations and the CPU is applied in the sequence of the algorithm and to perform smaller calculations. To validate the proposed approach some tests is presented to compare computational time of the GPU+CPU (heterogeneous environment) and CPU (serial way) modes. (AU)
