This paper presents an effective method for the identification of candidate bus for DSTATCOM placement for the minimization of power losses and improvement of voltage profile in radial distribution system with load modeling. The D-STATCOM is modeled for determination of its size by assuming the voltage magnitude as 1 p.u. at the candidate bus. The validity of the method is tested on the standard IEEE 33-bus radial distribution system by performing load flow analysis after compensating the candidate bus using MATLAB software. The results obtained are compared without and with the D-STATCOM for all load models. The voltage profile and the losses reduction is obtained for IEEE 33 bus test system with the optimal placement of D-STATCOM based on the sensitivity index.

“…In comparison to the indices L and Lp, the index Lv has very good agreement with the insolvability condition of system using conventional load flow techniques [18]. In Banerjee et al [19], a local voltage stability index has been proposed to determine the weakest branch of the distribution system. According to this criterion, the branch which may reach to unity as loading increases can treat as weakest branch in the network.…”

This paper presents the static voltage stability analysis of RDS. Initially the performance of RDS is evaluated using backward/forward load flow considering voltage-dependent load modeling. Later, the load flow solution is used for determining the static voltage stability of the system. The analysis is performed for different type of loads such as constant power, constant current, constant impedance, residential, industrial, commercial, agricultural and electric vehicle loads. The simulations are performed for standard and optimal reconfigured topology of standard IEEE 33-bus test system. The comparative study reveals the importance of load type and topology while assessing the static stability analysis of radial distribution systems.

“…The loads generally play a key role in voltage stability analysis and therefore the voltage stability is known as load stability. Literature survey shows that a major work has been done on the voltage stability analysis of transmission systems, but so far the researchers have paid very little attention on the voltage stability analysis for a radial distribution network [4][5][6][7][8][9][10][11][12][13][14] in power system. A radial distribution system consists of root node, main line, lateral line, sub lateral line and minor line with some uniform and non-uniform tapings.…”

The paper presents voltage stability analysis of radial distribution networks under critical loading conditions without and with shunt capacitor. A new voltage stability index is proposed for identifying the node, which is most sensitive to voltage collapse. The effectiveness of the proposed method without and with considering shunt capacitor has been successfully tested on a 12.66 kV radial distribution network consisting of 33 nodes and the results are found to be in very good agreement.
