This study suggests a low-cost configuration that uses static VAR compensation (SVC) technology to reduce losses and improve the voltage profile through VAR compensation. The two components of SVC are TCR and TSC. The TSC scheme is employed in this case because it doesn''t emit any harmonics and doesn''t need to be filtered, making it a

The tolerance boundary for a distribution network with a voltage level of 400 V may be ±10 %. In this case, the voltage of 430 V is commonly measured in the distribution networks. This effect may be caused by the usage of non-linear devices (generation of higher harmonics), low short-circuit power of voltage sources (voltage fluctuation), etc. We recommend using capacitors with

The low voltage power capacitors comply with most national and international standards. Other voltages up to 1,000 V are available on request. Capacitor elements made of metallised polypropylene film are self-healing and dry without impregnation liquid. Each capacitor element is individually protected with patented internal fuse protection.
As most of DGs and loads in LV distribution networks are single phase, the unbalance can be compensated by employing single-phase VSIs. In , a control method of the single-phase H-bridge PV-VSI was proposed for compensating the voltage unbalance at a critical bus.
Two consensus strategies based on cooperative control of PEVs and PV were designed for voltage unbalance compensation and voltage regulation. Charging and discharging of PEVs considering available PEV power and capacity were coordinated, and APCs among PVs were required during the over voltage time.
An increasing number of single-phase loads and renewable energy resources (RESs), such as single-phase rooftop PV units, are unevenly distributed in low voltage (LV) distribution networks. This exacerbates unbalanced conditions in the network which in turn adversely affects the power quality, stability and reliability.
Unbalanced voltages of split DC-bus capacitors could deteriorate performance and lead to instability. In a re-configurable network, multi-objective DE optimization algorithms for EVs and DGs were developed using primary and secondary centralized controllers. DSO could dynamically re-sequence phase at each bus for compensation.
