Computer Physics Communications Furthermore, voltage instability may occur in many different sub-regions of the system. The optimal placement and sizing of DG in radial distribution system as proposed for capacitor is employed with n bus, laterals and sub-laterals as shown in Fig 1. The VSI formula is derived from simple current flow equation based on figure 2. More specifically, an alternative embodiment would search for the value of alpha that is as small as possible, i. Microgravity Science and Technology S1,
The multiple contingency analysis is to be performed for a region of a power system having a plurality of buses and a plurality of sources of reactive reserves coupled thereto. Journal of Fluid Mechanics Each reactive reserve basin comprises at least one of the sources of reactive reserves selected in dependence upon a measure of the reactive reserves depleted at a predetermined operating point of the power system. Conditional block checks whether or not there is a Q-V curve with a positive minimum. Crossref Bifurcation and stability of a three-hinged rod under a conservative load.
A comparison is also made between this index and the impedance ratio used by Sterling et al. Momoh, Y. The deletion of these voltage control areas from reactive reserve basins for those contingencies will make the contingency ranking based on reactive reserve basin reactive reserves more accurate without requiring the user to make judgments. The list of line outages are used to produce a set of severe single and double line outage contingencies. In the search procedure for alpha, a bounded interval of potential values of alpha is first selected.

Crossref A bifurcation study of convective heat transfer in a hele-shaw cell. Journal of Nonlinear Science This can extend the stability margin of dynamic loads, which can result in loss of stability with voltage dips. Next, the subset of all of the reactive supply resources within voltage control areas that exhaust all of their reactive supply at the minimum of the Q-V curve computed at any bus in the test voltage control area is determined at block Overall the book evaluates different options of computational intelligence, communication technology and decision support system to design various aspects of Smart Grid.
Such contingencies can have a reactive reserve basin that does not contain the pre-contingency reserve basin voltage control area that is totally or partially disconnected from the test voltage control area by the line outage contingency. Crossref Boundary-derivative direct method for computing saddle node bifurcation points in voltage stability analysis.
The procedure involves determining, at blockthe voltage control areas, i. It incorporates all the essential factors of Smart Grid appropriate for enabling the performance and capability of the power system. As seen therein, a contingency selection and ranking for contingencies and operating changes that bring a particular test voltage control area and its reactive reserve basin closest to voltage instability is performed.
In order to attempt to prove that the absence of a converged solution is caused by voltage instability, substantial manpower and computer processing time are required.
Numerical Methods for Bifurcation Problems. These single contingencies include single line outages and single generator outages. The VSI formula is derived from simple current flow equation based on figure 2.
In blockthe plurality of buses are grouped into voltage control areas in dependence upon a corresponding reactive power versus voltage relationship for each of the buses. International Journal of Engineering Science The static load models are expressed interms of active and reactive powers which are functions of the bus voltages.
In practice, the minimum of the Q-V curve can be obtained using a standard Newton-Raphson algorithm. Physics of Fluids Crossref A bifurcation study of convective heat transfer in porous media.
Also, the chapter cater to the needs of undergraduate as well as graduate students, professional engineers, and researchers who all are working in the domain of power system voltage stability.
In blockthe severe single and multiple contingencies are simulated and ranked based upon the reactive reserve in a reactive reserve basin.
