Abstract

This paper presents an Upgraded Binary Grey Wolf Optimization(UBGWO) for optimal deployment of Phasor Measurement Units (PMU) in power system to obtain complete system observability. The cost increases with increase in allocation of PMUs at every bus, therefore PMUs should be allocated in optimal way so that complete system observability is obtained. The Redundancy of Bus Index (RBI) at every bus is considered to assess performance of every bus connected to the system. Complete System Observability Index (CSOI) is proposed to evaluate the complete performance of the proposed strategy to optimize PMU locations. The proposed UBGWO is programmed in MATLAB software and examined with IEEE 14, 30 and 57 bus networks to obtain complete system observability with optimal allocations. To validate the proposed method, the results are compared with standard methods.
