Distributed Generation Allocation to Improve Steady State Voltage Stability of Distribution Networks Using Clonal Selection Algorithm

Abstract

In this paper, our purpose would be optimal distributed generation allocation for stability enhancement, in radial distribution systems. Voltage stability is related with stable load and acceptable voltage in all system buses. The instability is divided into steady state and transient voltage instability Based on the time spectrum of the incident of the phenomena. The analysis is accomplished using a steady state voltage stability index which can be evaluated at each node of the distribution system. Several optimal capacities and locations are used to check this result. The location of DG has the main effect voltage stability on the system. effect of location and capacity on incrementing steady state voltage stability in radial distribution systems are examined through clonal selection algorithm and finally the results are compared to (PSO) on the terms of speed, accuracy and convergence
