“…Series voltage regulator and shunt capacitors are the two conventional ways of maintaining voltages of the distribution system within acceptable range. But, these devices have some disadvantages that are conventional series voltage regulators cannot generate reactive power and have slow response because of their step by step operations and shunt capacitors are unable to generate continuous variable reactive power and its natural oscillatory behavior with inductive components [2]. The D-FACTS devices can play an important role to overcome these problems with efficiently reducing the line power losses, correcting power factor, and improving voltage profile of the power system.…”

In this paper, an approach for optimal placement of D-STATCOM in mesh distribution systems using sensitivity approaches is proposed. The main contributions of the paper are as follows: (i) Optimal D-STATCOM placement based on the new voltage sensitivity index in mesh distribution system, (ii) optimal D-STATCOM size determination for seasonal loads with load growth scenario, (iii) comparison of D-STATCOM placement and size determination with the existing sensitivity methods, and (iv) impact of optimal D-STATCOM placement on voltage stability margin enhancement, energy loss reduction and cost of energy savings.The results of voltage profile improvement, reduction in power losses, reduction in cost of energy loss, improved voltage stability margin, cost of energy loss savings, installation cost of D-STATCOM and annual savings are obtained for UK 38 bus practical mesh distribution system.

“…Conventional series voltage regulators are commonly used for voltage regulation in distribution system [1,2,3]. But these devices cannot generate reactive power and by its operation only force the source to generate requested reactive power and they have quite slow response as these operations are step by step [4]. Shunt capacitors can supply reactive power to the system but they are not capable to generate continuously variable reactive power.…”

This paper proposes a hybrid methodology to identify the optimal location and sizing for distribution static compensator (DSTATCOM) placement as a distribution flexible ac transmission system (DFACT) device in a distribution system, by using fuzzy and Penguins search optimization algorithm (PeSOA). The main purpose is to reduce the power loss and to improve the voltage profile of distribution networks. The PeSOA is meta-heauristic search method inspired from the hunting strategy of penguins. Here fuzzy is used for finding the optimal location and PeSOA is used to find the size of DSTATCOM in radial distribution networks. The feasibility and satisfying performance of the proposed method is examined on the IEEE 33-bus and 69-bus distribution system.

“…Another difficulty associated with the application of distribution capacitors is the natural oscillatory behavior of capacitors when they are used in the same circuit with inductive components. Which results in the well-known phenomena of ferroresonance and/or self-excitation of induction machinery [10].…”
