The primary aim of this research work is to address the different objectives such as (i) exploitation of the AC model and development of the new objective functions, (ii) utilization of current phasors exclusively instead of voltage phasors which are used by most of the existing researchers, (iii) tackling of PMU outage issues, (iv) incorporation of faulty PMU and measurement uncertainty into the mathematical models, (v) detection of parallel line outage and (vi) ensuring the cost-effectiveness of the developed models. This entire research work is accomplished phase-wise to achieve the...

This book presents the research works and investigations related to the contingency due to line outage. Firstly, the detail assessment of the impact of line outage has been studied through PV curve method. Later on, investigation has been carried out to find the most critical line in normal loading condition. In view of this, ranking of the line outage contingencies are done on the basis of proposed overall severity index (OSI) comprising of two index i.e. active power deviation-based index and voltage deviation based index. Furthermore, the critical contingency is identified though...

This book presents the research works related to the development of new algorithms for line outage identification using voltage phasor of PMU. Three new voltage phasor-based algorithms are introduced. The proposed three models are 1) Direct comparison of phasor angle measurement (DCPAM) model 2) Comparison of bus current injection (CBCI) model 3) Comparison of bus power injection mismatch (CBPIM) model. The proposed algorithms also consider the constraints like PMU outage issue and measurement noises which reflect the novelty and reliability of the methodology. The performance of the proposed...
