Abstract
At present time concerted efforts are being made for the implementation of smart grid technologies. PMUs play a significant role in the wide area monitoring system (WAMS). The major advantages of the WAMS include dynamic wide area measurements with faster rate and better accuracy. Observability of a complete power system with a minimum number of PMUs has always remained a challenge. This paper suggests a binary integer linear programming approach for finding out the optimal locations of PMUs in a system. Two indices viz. BOI (Bus Observability Index) and SORI (System Observability Redundancy Index) have been suggested to rank the various possible solutions of an OPP. IEEE 14, 24, 30 and New England 39 (NE 39) bus systems have been considered for simulation and the results show excellent computational efficiency of the algorithm.
