Optimized Voltage Stability for Maximum Loadability Using Neural Networks
This paper proposes a Neural Network-Based method for on-line maximum loadability estimation, for an optimized power system voltage stability profile. A simulated annealing optimization technique for optimal voltage stability profile through out the whole power network was used. The minimization of the voltage stability index at each individual load bus as well as the global voltage stability i...
متن کاملIdentification of Weak Bus and Voltage Stability Enhancement
This paper describes sensitivity indicator method to identify weakest bus of the system. It also describes method of calculating the amount of reactive power to be injected at the load bus to avert the voltage instability as the load on the load bus increases. In this paper IEEE-57 BUS system has been considered. First, the weakest bus is identified using sensitivity indicator method. Then Load...
متن کاملTransmission Line Loadability Improvement Using Facts Device
With the recent trends towards deregulating power systems around the world, transfer capability computation emerges as the key issue to a smoothly running power market with multiple transactions. Enhancement of available transfer Capability (ATC) is an important topic in current deregulation environment considering loop flows and heavily loaded lines. The thermal limits of transmission lines, v...
متن کاملA Weak Discrete Maximum Principle and Stability
Let ÍÍ be a polygonal domain in the plane and Sy(£l) denote the finite element space of continuous piecewise polynomials of degree < r — 1 (r > 2) defined on a quasi-uniform triangulation of ii (with triangles roughly of size h). It is shown that if un e Sy(Sl) is a "discrete harmonic function" then an a priori estimate (a weak maximum principle) of the form ""ftHi^n) < CII"/illL„.(3iï) holds. ...
متن کاملInvestigation of Voltage Stability Indices to Identify Weakest Bus (TBC)
This paper proposes a new index to determine the static voltage stability of the load buses in a power network for certain operating conditions and hence identifies load buses which are close to voltage collapse. The proposed index is formulated from the quadratic equation derived from a twobus network and is computed using the apparent power and the line impedance. The proposed index shows how...
