Distribution Network Reconfiguration and D-STATCOM Allocation using Variational Technique

This paper explores feeder reconfiguration alongside distributed static compensator (D-STATCOM) in distribution systems. An efficient method is present to optimize the radial distribution structure by means of reconfiguration along with allocation of distributed static compensator. Network Reconfiguration of distribution system is a momentous way of revising the power flow through the various alternative lines with an objective of minimizing real power loss distribution system. A precise and load flow algorithm is useful and the objective function is formulated to solve the fitness function, which includes D-STATCOM for reactive power compensation to minimize the power losses. Particle swarm optimization is exploited to restructure and recognize the best strap switches for minimization of real power loss in a distribution network. Fuzzy analysis is projected to find the optimal location of D-STATCOM. Variational Technique is used to identify the optimal size of D-STATCOM. This has been tested on IEEE 33-bus system to prove the adequacy of the technique using MATLAB software.
