“…In this paper, load buses 21, 24, 25, and 19, and the corresponding lines 17‐21, 22‐24, 11‐25, and 10‐19 of the 26‐bus test system, are randomly selected based on the loadability of each load bus. Lines 24‐25, 39‐57, and 30‐31 among others of the IEEE 57‐bus have been reported to be the most critical lines of the system . Load buses 25, 30, 31, 32, 33, and 57 are also found to be the weak buses of the IEEE 57‐bus test system .…”

Summary Voltage stability has of recent been a subject of growing concern to power system utilities. In this paper, 2 techniques, one based on topological structure of power networks and the other on the conventional power flow solution, are proposed for voltage stability analysis. The network structural characteristics theory participation factor proposed is formulated to identify the weak bus of the system. The voltage stability enhancement is achieved through the incorporation of power electronic–based thyristor‐controlled series compensator device. This is done by modifying the admittance matrix and network structural characteristics theory participation factor formulated to incorporate the effect of variable reactance of thyristor‐controlled series compensator device. The second suggested approach based on power flow is also investigated. The results of both techniques are compared with the conventional approaches. The results of simulations obtained show that voltage stability enhancement can significantly be achieved from the network structural point of view, as it saves time and reduces system computational burden.

“…Using power flow of these indices can be calculated and line having maximum value of the index is the most critical line referred to that bus [10]. Different multiple techniques have been implemented in previous research papers to find out the best possible location of these devices using stability indices but they involve many complexities in power flow solution and calculations of indices [11]. In this paper simple and effective method has been implemented for finding the optimal location of FACTS device based on static stability, stability index.…”

This paper is directed towards the key issues of the power system to improve the voltage stability of the system and to reduce the real power losses in the system. The analysis has been done on IEEE 14 bus system by using two FACTS devices namely TCSC & STATCOM for power system stability under different loading conditions. The simulation is done on PSAT (Power System Analysis Tool-box) in MATLAB and optimal location is found out by calculating VCPI (Voltage Collapse Proximity Index) and LQP (Line Stability Index) to find the critical line with respect to a bus. Results clearly indicate that placement of FACTS devices at appropriate location can lead to control of power flow in the lines and keep the bus voltages at desired level and hence enhance the steady state voltage stability of the system.

“…Other indices which also can be calculated using current state (or a few nearby states in the case of impendence matching index based on Thévenin equivalent) are constructed to have a normalized range, typically between zero and one. Definitions and comparisons of these indices can be found in [15,16,17,3,18,19].…”
