An Efficient Approach for Fast and Accurate Voltage Stability Margin Computation in Large Power Grids
This paper proposes an efficient approach for the computation of voltage stability margin (VSM) in a large-scale power grid. The objective is to accurately and rapidly determine the load power margin which corresponds to voltage collapse phenomena. The proposed approach is based on the impedance match-based technique and the model-based technique. It combines the Thevenin equivalent (TE) networ...
متن کاملReactive Power Pricing in an Open Access Environment Considering Combined Optimum Voltage Profile and Voltage Stability
In a de-regulated open access environment, reactive power is one of the ancillary services which must be provided by an Independent System Operator (ISO). In this paper, a new algorithm is proposed in which reactive power resources are initially so tuned that optimum security in terms of voltage profile and voltage stability are achieved while at the same time, the system losses are minimized. ...

متن کاملEstimating the Active Power Transfer Margin for Transient Voltage Stability
On-line security analysis is one of the important functions for modern power system control centers. It is well known that voltage magnitudes alone are poor indicators of voltage stability or security. Voltages can be near normal with generators, synchronous condensers, and SVCs near current limiting levels resulting in a possible voltage collapse. For on-line application, a pattern matching or...
متن کاملVoltage Stability Margins and Risk Assessment in Smart Power Grids
This paper presents a quantitative framework for assessment of voltage stability in smart power networks. First, new stability indices similar to gain and phase margins in linear time invariant control systems are introduced. Then, a novel risk assessment framework incorporating the new stability indices is developed to methodologically quantify the voltage stability risks a power system faces ...
