This paper presents an investigation of five-Level Cascaded H – bridge (CHB) Inverter as Distribution Static Compensator (DSTATCOM) in Power System (PS) for compensation of reactive power and harmonics. The advantages of CHB inverter are low harmonic distortion, reduced number of switches and suppression of switching losses.The DSTATCOM helps to improve the power factor and eliminate the Total ...

Abstract—The global energy consumption is increasing persistently and need for distributed power generation through renewable energy is essential. To meet the power requirements for consumers without any voltage fluctuations and losses, modeling and design of multilevel inverter with Flexible AC Transmission System (FACTS) capability is presented. The presented inverter is provided with 13-leve...

Green energy sources are implemented for the generation of power due to their substantial advantages. Wind is best among renewable options generation. Generally, wind system directly connected with network supplying power. In direct connection, there an issue managing quality (PQ) concerns such as voltage sag, swells, flickers, harmonics, etc. order enhance PQ in a conversion (WECS), peripheral...

Over the recent period of time, power quality problems have been marked as a buzzing issue with regards to promote delicate or miniature electronic devices where Voltage sag problem is most frequently occurring well detrimental problems. Thus, purpose this study assuage voltage using proposed Distribution Static Synchronous Compensator (D-STATCOM). Utility distribution networks, sensitive indus...

This paper presents a nonlinear controller design for a DSTATCOM connected to a distribution network with distributed generation (DG) to regulate the line voltage by providing reactive power compensation. The controller is designed based on the partial feedback linearization which transforms the nonlinear system into a reduced-order linear system and an autonomous system whose dynamics are know...

The Static Synchronous Compensators (STATCOMs) have been recoginzed as the most effective solution for dynamic reactive power compensation, voltage stability enhancement and subsynchronous resonance damping purposes in the electric power systems. The STATCOMs in the distribution utilites (DSTATCOMs) are increasingly investigated for dynamic reactive power compensation and power quality improvem...

This paper presents modeling and analysis of 12-phase distribution static compensator (DSTATCOM), which is capable of balancing the source currents in spite of unbalanced loading and phase outages. In addition to balance the supply current, the power factor can be set to a desired value. The theory of instantaneous symmetrical components is used to generate the twelve-phase reference currents. ...

Abstract: Voltage sag is considered to be the most serious problem of power quality. It is caused by faults in the power system or by the starting of large induction motors. Voltage sag causes about 80% of the power quality problems in power systems. One of the main reasons for voltage sag is short circuit fault, which can be compensated for by a distribution static compensator (DSTATCOM) as an...

Photovoltaic systems have been increasingly used in the generation of electrical energy because of the cost of energy produced from fossil fuels is rising day to-day and there by photovoltaic energy becomes a promising alternative source for fossil fuels. Power quality is the major problem that occurs between grid to end user transmission lines. DSTATCOM is the one of the power quality compensa...
