“…The concept of voltage performance index suggested by K. Nara et al in [12] is used for defining the composite security index. The proposed index is defined in such a way that it completely eliminates the masking problem, and provides a proper definition of security in which the secure state is indicated by an index value of '0', while a value greater than '1' indicates insecure state.…”

This paper proposes a composite security index for the on-line critical contingency selection and ranking in terms of both the line flow and bus voltage limit violations. In order to evaluate the vector valued security index, a scalar index is derived based on the concept of hyper-ellipse inscribed within a hyperbox. The proposed index, which provides an efficient method for filtering and ranking the credible contingencies are defined in such a way that a proper differentiation between the secure and insecure states are possible. This avoids the need for specifying any stopping criteria for contingency analysis. Test results of security evaluation using WSCC 9-bus system and IEEE 30-bus system are presented to show the effectiveness of the proposed method.

“…The concept of the N-1 security has been proposed in [1][2][3][4][5][6][7], and is widely used globally in various power systems at present. On the other hand, various probabilistic approaches have been proposed for keeping up power system security taking into account possible events as well as operation conditions with their occurrence probabilities [8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Penetration of large amount of renewable energy sources (RES) may introduce considerable uncertainties in power systems making difficult the planning and operation tasks. This paper proposes a new concept named "Robust Power System Security (RS)" in order to investigate power system security in the presence of uncertainties. RS region is defined as an area of power system operation in which the system is secure regardless of uncertainties in parameters such as RES outputs. When the size of the uncertainties is specified, RS region is identified. It is observed that the region tends to shrink and disappear as the uncertainty increases. Emerging problems concerned with security issues in future power systems are investigated.Simulations under large RES penetration are carried out using a three generators test system. Possible applications of the proposed concept toward real-time operation problems are discussed for keeping up the security. Index Terms-RobustPower System Security(RS), Renewable energy sources(RES), Transient stability, Uncertainties. Naoto Yorino (M'90) received the B.S., M.S.

Summary This article presents the concept of voltage instability and a critical review of the literature available for detecting voltage instability in the power system. Initially, the problem of voltage instability, the signification of P‐V, Q‐V curves, the effect of load models, on‐load tap changer (OLTC), and over‐excitation limits of generators on voltage instability are lucidly explained. A very brief description of conventional methodologies for voltage instability detection is also presented. This literature review mainly focuses on methodologies based on synchrophasor measurements including both local and global measurements. These methodologies' feasibility for real‐time application has been investigated. The indices that are compared for instability detection may serve as an introduction to measurement‐based voltage instability detection methodologies. The measurement‐based indices that are analyzed and compared are mainly based on the concept of Thevenin parameters estimation, generator equivalent models, nodal reactive power loss concept, and apparent power difference criteria. Thus, this paper attempted to compile all the work reported so far for voltage instability detection using synchrophasor measurements and for each methodology merits and demerits are lucidly discussed and are tabulated.
