Transmission systems power quality monitors allocation

This work develops and tests a branch and bound algorithm for solving optimum allocation of power quality monitors in a transmission power system. The optimization problem is solved by using 0-1 integer programming techniques and depends highly on network topology. The algorithm, which is implemented in Matlab software, minimizes the total cost of the monitoring system and found the optimum number and locations for monitors on the network studied, under a set of given network observability constraints. Case studies are presented for IEEE test networks and for CEMIG actual transmission power systems. Current and voltage values are estimated by using monitored variables to validate the obtained results.
