Optimal Sizing and Siting of Distributed Generators by Exhaustive Search

Abstract

Dispersed generation generally refers to power generation on the customer side of a power network. This article demonstrates the improvement in network parameters which could be achieved by using single and multiple Distributed Generation units in three selected standard networks. A reliable multi variable method is used for finding optimal installation point and size of distributed generation units. Their sites and sizes are recognized by implementation of a proposed method with exhaustive search. Optimization has been applied on network total active and reactive losses together with voltage variation. IEEE 6, 14 and 30 buses standard networks have been selected as study cases. The total active and reactive power losses are minimized while voltage profile is improved by installing Distributed Generation units on recognized optimal points with achieved optimal size.

Protection Coordination of Properly Sized and Placed Distributed Generations–Methods, Applications and Future Scope

“…The main objective is to reduce overall power losses in the network. (4) Exhaustive search-a multi-object technique, used in [19][20][21][22], used for finding proper location and size of DGs with main focus on reliability improvement and loss minimization at fixed and variable load models. The time-varying behavior of renewable sources and loads were considered in [23].…”
