[1] We use limb profiles to quantify the long‐wavelength topography of the Saturnian satellites. The degree 2 shapes of Mimas, Enceladus, and Tethys are not consistent with hydrostatic equilibrium. We derive 2‐D topographic maps out to spherical harmonic degree 8. There is a good correlation with topography derived from stereo techniques. If uncompensated,(More)
Voltage instability is a major problem that is attracting worldwide interest because of its consequence of voltage collapses. These days' Kerala power system operate closer to their stability limits because of the economic considerations, making large amount of power transfer from long distance and an inadequate supply of reactive power which contribute to(More)
It is widely accepted that transient stability is an important aspect in designing and upgrading electric power system. This paper covers the modeling and the transient stability analysis of the wind integrated IEEE 14 test bus system. This paper investigates the enhancement of transient stability using central area controller in a wind integrated power(More)
Voltage instability is a major issue that attracts worldwide interest because of its consequence of voltage collapses. These days power systems operate closer to their stability limits, transferring large amounts of powers from long distance and an inadequate supply of reactive power contribute to system voltage instability and eventually lead to voltage(More)
Micro-grid is a discrete energy system consisting of distributed energy resources capable of operating in tandem or independently from the main grid. Nowadays the former one is preferred. The smart interconnection of distributed energy (DG) resources determines the quality of the power supplied by the energy source. It is obtained by the appropriate control(More)
The efficient and optimum economic operation and planning of electric power generation systems have always occupied an important position in the electric power industry. Main aim of electric power utilities is to provide high quality, reliable power supply to the consumers at the lowest possible cost while operating to meet the limits and constraints(More)
