Voltage stability is an important issue of power system stability. This work is concentrated on finding weak busses with voltage stability index analysis for Radial Distribution System (RDS). In this work Optimization of Multiple Distribution Generating Unit using Voltage Stability Index and Analytical Approach with Forward, Backward Sweep method (FBS). In this work a novel approach has been implemented to reduce the losses in the radial distribution system. This work has been done in two phases. From the first phase of work identification of weak nodes with voltage stability index, which are most sensitive to voltage collapse using the Branch Injection and Branch Current (BIBC) and Branch Current and Branch Voltage (BCBV) matrix have been analyzed. This feature enables us to set an index threshold to monitor and envisage system test case stability, so that a proper action can be taken to prevent the system from collapse. From second phase, optimal allocation of Multiple DG with the objective as minimizing the distribution line losses with cost attributes. . It is vitally essential to characterize the size and location of multiple DGs’ to be placed and the cost of DG’s, with the cost of line loss when the DG is active. By virtue of some intrinsically characteristics of distribution systems, as the structure is radial in nature, immensely colossal number of nodes, with an extensive range of R/X ratios, the conservative techniques diverges in the distribution system for the determination of optimum size and location of these multiple Distributed Generations (DG). The projected approach and results are validated on IEEE 33,69 bus standard test systems.
KEYWORDS
A Forward, Backward Sweeping method (FBSM) has been implemented to find out the bus voltages of radial distribution network. Comparison of minimum voltage at weak nodes for constant power, constant current and constant impedance load types are done. Optimal location with DG has been found using analytical approach to improve the voltage profile. The main theme of this work is voltage profile improvement rather than voltages stability improvement.
