Optimal Allocation of Pmu Considering Controlled Islanding of Power System Using Hybrid Optimization Algorithm

This paper proposes an optimal allocation of phasor measurement unit (PMU) placement model under controlled islanding of power system such that the power network remains observable under controlled islanding condition in addition to normal operation condition. The optimization objective of proposed model is to reduce the number of installed PMUs by using hybrid optimization algorithm. The objective is pooled together with a weighting variable such that the optimal solution with less PMU number would be achieved from the model. To decrease the number of required PMUs, the significance of zero-injection bus is considered and incorporated into the model. IEEE standard systems used to test the presented model. Results are presented to exhibit the effectiveness of the proposed technique.
