Minimizando o custo global de Infraestrutura de Comunicação e alocação de PMUs em WAMS: uma abordagem via grafos

In this paper, we present a new method for the design of WAMS (Wide Area Measurement Systems). State estimation is responsible processing measurements in real time and providing complete secure database Wide Systems, therefore power system increasingly dependent on PMU measurements. The high cost communication infrastructure together with encouraged development placement solutions order to ensure observability system. methodology has an emphasis optimizing infrastructure, so that smallest number PMUs satisfies condition lower total cost. Our results show effectiveness proposed when compared research recent previous works. simulations were performed using IEEE-14, IEEE-30, IEEE-118 IEEE-300 standards.
