Fuzzy logic application for network contingency ranking using composite criteria (2007)

Thukaram, D, Jenkins, L, Khincha, HP, Visakha, K, Ravikumar, B

Electric power systems are exposed to various contingencies. Network contingencies often contribute to over-loading of network branches, unsatisfactory voltages and also leading to voltage collapse....

Optimum allocation of reactive power for voltage stability improvement in AC-DC power systems (2006)

Thukaram, D, Jenkins, L, Visakha, K

The dependence of the system voltage stability on reactive power distribution forms the basis for reactive power optimisation. The technique attempts to utilise fully the reactive power sources in...

Improvement of system security with unified-power-flow controller at suitable locations under network contingencies of interconnected systems (2005)

Thukaram, D, Jenkins, L, Visakha, K

The operation and planning of large interconnected power systems are becoming increasingly complex. To maintain security of such systems, it is desirable to estimate the effect of contingencies and...

An Approach for Real Power Scheduling to Improve System Stability Margins under Normal and Network Contingencies (2004)

Visakha, K, Thukaram, D, Jenkins, Lawrence

In the present day power system planning and operation, considerable interest is being shown in system security and stability analysis. Pattern of load sharing / generation scheduling that results in...

An approach for evaluation of transmission costs of real power contracts in deregulated systems (2004)

Visakha, K, Thukaram, D, Jenkins, Lawrence

This paper presents a usage-based transmission cost allocation method based on a new set of line utility factors (LUFs), which provides power transaction impact on each element of the network in...

An Approach for Evaluation of Transmissidn Charges Based on Desired and Deviations of Power Contracts in Open access (2003)

Visakha, K, Thukaram, D, Jenkins, Lawrence, Khincha, HP, Routray, PK

Transmission charge allocation is one of the major issues in transmission open access faced by the electric power industry. This paper introduces a new method of transmission charge allocation based...

Selection of UPFC Suitable Locations for System Security Improvement Under Normal and Network Contingencies (2003)

Visakha, K, Thukaram, D, Jenkins, Lawrence, Khincha, HP

Electric power systems are exposed to various contingencies. Network contingencies often contribute to overloading of network branches, unsatisfactory voltages and also leading to problems of...

A Three Phase Fault Detection Algorithm for Radial Distribution Networks (2002)

Thukaram, D, Khincha, HP, Jenkins, L, Visakha, K

Distribution networks, unlike in transmission system, may not be provided with protective devices or circuit breakers in each branch of the feeder. For any fault in the feeder, a large part of the...
