“…The passive strategy [52][53][54][55][56] utilises capacitive shunt compensation as well as phase balancing without deploying power electronic devices to correct load unbalance and overloads in the distribution network. In contrast, the active strategy exploits a capability of power electronics such as line voltage regulator (LVR) [57], advanced on-load tap changer (OLTC) [58][59][60][61], reactive power compensator (RC) [62,63], zero sequence current compensator (ZSCC) [64], distributed static synchronous compensator (DSTATCOM) [65][66][67][68][69][70][71], dynamic voltage restorer (DVR) [72][73][74][75][76][77], unified power quality conditioner (UPQC) [78][79][80][81][82][83] to compensate voltage unbalance. Since this power electronics equipment is expensive leading to additional investment cost, they are therefore scarcely deployed in LVDN.…”

“…A UPQC [79] is similar to a UPFC but has more power quality improvement functionalities. A UPFC is typically employed in the transmission network [80], while a UPQC is normally employed in the distribution network. Due to a nearly balance transmission network, the UPFC only provides a shunt and/or series compensation.…”

Voltage unbalance has gained more attention due to a rapid increase in single-phase distributed energy resources (DERs) penetration compound with existing unbalance characteristics of low voltage distribution network. The purposes of this article are to summarise various techniques on voltage unbalance compensation from three different strategies: (1) techniques based on passive approach and advanced power electronics; (2) Techniques based on three-phase DERs; (3) techniques based on single-phase DERs. In addition, a novel voltage unbalance compensation technique that applies a voltage sensitivity analysis along with a symmetrical component concept to meet a desired voltage unbalance factor (VUF) is introduced in this article. Coordination among single-phase DERs that contributes in the voltage unbalance compensation is also considered. In order to evaluate the effectiveness of this proposed technique, its results are compared with the results that are obtained using a current unbalance compensation strategy. The results indicate that the novel technique proposed in this study provides more stable voltage unbalance compensation while successfully achieving the specified VUF thresholds.

This study presents the study of configuration, working, controller of the fundamentals of the STATCOM and significant function of each custom power devices. Flexible Ac Transmission Systems (FACTS) controller achieves fast control response time as well as providing better control than conventional control. However, Static Synchronous Compensator (STATCOM) could be seen as one of the key Flexible Ac Transmission Systems (FACTS) devices which are based on the Voltage Source Converter (VSC) technology. The capacitive and inductive compensation could be provided by the controller and could as well control output current over the rated maximum capacitive or inductive range without depending on the ac system voltage.

“…Fast progression in the field of power electronics has already started to influence the power industry. This is one direct outcome of the concept of flexible ac transmission systems (FACTS) aspects, which has become feasible due to the improvement realized in powerelectronic devices [3].FACTS devices was first introduced in 1980s by Narain G.Hingorani [4]. In principle, the FACTS devices could provide fast control of active and reactive power through a transmission line.…”
