“…More specifically, due to the availability of pricing information, the objective function of capacitor placement is often defined as the power loss reduction [1]- [12] and capacitor purchase cost minimization [1]- [6], [8], [9], [11]. Additionally, other typical objectives, such as capacitor installation cost [1], [2], [4], [7], [8], [10]- [12], saving from system capacity release [5]- [7], [12], capacitor operation and maintenance cost [11], [12] have also been utilized in the previous studies. For the capacitor placement problem many solution techniques have been proposed and they can be generally divided into three categories: analytical, numerical programming, heuristics and a comprehensive survey can be found in [9] and [13].…”

Delta-connected switched capacitors are common in three-wire MV distribution systems as found in Europe and Australia but the majority of past studies focus on star-connected capacitors as applied in North America. This study presents a comprehensive optimization based sequential strategy and a multi-objective optimization based real-time strategy for the optimal placement and control of delta-connected switched capacitors. Considering load variations, a comprehensive optimization for capacitor placement is formulated to maximize the net annual returns from network loss reduction and capacity release. A sequential strategy based on loss sensitivity analysis is presented for efficient capacitor placement on large-scale unbalanced distribution networks. Then a capacitor control strategy is proposed to simultaneously minimize network losses, voltage deviations and voltage unbalance factor (VUF) while a weighted sum method reflects the preferences on the mutually conflicting control objectives. For the mixed integer programming (MIP) problems of capacitor placement and control, an improved backward/forward sweep (BSFS) load flow based particle swarm optimization (PSO) method is used. Finally, the robustness of the proposed capacitor placement and control strategies are verified by comparison against existing popular schemes through detailed simulations over 24 h on a real unbalanced Australian MV network.Index Terms-Capacitor switching, optimization methods, power capacitors, power distribution planning, power quality.

“…Abdul-Salam et al [6] proposed a heuristic technique, which brings about the identification of the sensitive nodes that have a very large impact on reducing the losses in the distribution systems. Chen et al [7] developed a systematic method of optimally locating and sizing the shunt capacitors compensation on distribution feeders by taking into account the mutual coupling effect among phase conductors. The proposed method was demonstrated on unbalanced and balanced systems.…”

This article presents a simple method for investigating the problem of contemporaneously choosing optimal location and size of shunt capacitors in threephase unbalanced radial distribution systems. The main objective function formulated consists of two terms: cost of energy loss and cost related to capacitor purchase and capacitor installation. The problem of choosing optimal locations and sizes for shunt capacitors in an unbalanced radial distribution system is addressed with the two algorithms in this article-one is for selecting the best locations of capacitor placement and candidate node identification algorithm; the second is for the sizing of capacitors, a variational technique algorithm according to available standard size of capacitors. The objective function used in this article is to maximize the net savings in the distribution system. This article presents the results of simulations for 25-bus and IEEE 37-bus unbalanced radial distribution systems.
