A novel optimization-based power quality enhancement using dynamic voltage restorer and distribution static compensator

Abstract

The power assurance <span lang="EN-US">for distinct purchaser in the nation must be guaranteed through electric power distribution (EPD) system, subsequently EPD must be reliable, and well facilitating with power quality (PQ) in distribution framework. It will be much significant to keep up with PQ in power distribution (PD) framework for service continuity. The PQ issue basically emerge in distribution framework are voltage swell, sag, harmonics, and disparities in power. In this manuscript, the PQ development in photovoltaic (PV) PD framework for IEEE 33 and 57 bus frameworks is deliberated as the aim. The improvement is satisfied with FACTS pay gadgets of dynamic voltage restorer (DVR) and distributed static compensator (DSTATCOM). The butterfly optimizer (BO) and gray wolf optimizer (GWO) framework is deliberated for suggested work that implies a switching gadget and it compares the yield signal of DSTATCOM and DVR. In this proposed system DVR is compensated with an advanced GWO and DSTATCOM with BO for optimal location of FACTS devices in IEEE 33 and 57 bus systems are discussed like in the conventional paper as 13th bus for IEEE 33 system & 30th bus for IEEE 57 system.</span>

Power quality conditioning using two-level buck inverter based DSTATCOM

“…In view of improved design aspect, the LC coupled buck voltage source inverters (VSI) based DSTATCOM is proposed for providing the actual and reactive power in the PCC for the PQ improvement [11], [12]. This buck inverter is designed by considering the aspect of modular design, suitable selection of inductor, variable output power, and flexible for additional connection of the elements [13]- [15]. Apart from these, the variable switching frequency can be attained by using this proposed inverter.…”

Hybrid control mechanism-based DVR for mitigation of voltage sag and swell in solar PV-based IEEE 33 bus system

“…The feed-forward control using the PSO approach is adopted in DVR to mitigate the voltage disturbances. The DVR and DSTATCOM are integrated with gray wolf optimizer (GWO) and butterfly optimizer (BO) to improve the power quality issues, and it is analyzed by Chiranjivi and Swarnasri [39]. Saeed and Sheikhyounis [40] presented the PSO-artificial neural network (ANN) based unified power flow quality conditioner (UPQC) is designed to improve the power quality in DGs, which is caused by voltage disturbances.…”
