“…Bu sistemler kullanılarak, mekanik anahtarlamalı kompanzatörlere göre reaktif gücün dolayısıyla sistem gerilim seviyesinin daha hızlı ve yumuşak kontrolü mümkündür [45]. Ulaşılabilen literatürden, statik var kompanzatör (SVC), dinamik gerilim düzenleyici (DVR), dağıtım tipi statik kompenzatör (D-STATCOM) ve birleşik güç akış kontrolörü (UPQC) olarak isimlendirilen çeşitli FACTS elemanlarının, FV-DÜB'lerin bulunduğu sistemlerde gerilim profilinin iyileştirilmesi için kullanımı üzerine çalışmalara ulaşılmıştır [46][47][48][49][50][51][52][53][54]. Bu FACTS elemanlarının şematikleri Şekil 12'de sunulmuştur.…”

In today's power systems, the use of distributed generation units has become widespread in order to improve the voltage profile, increase system reliability, reduce line losses and increase energy efficiency. Among these distributed generation units, wind turbines and photovoltaic units have limited the use of traditional energy sources such as natural gas, coal and oil in electricity generation, thus they became important options for the prevention of environmental problems such as greenhouse gas emissions and global warming. However, these distributed generation units are connected to the grid via power electronics circuits and their energy sources are non-dispatchable. Thus, they lead to various power quality problems in the power systems. In this study, firstly, the latest technological case of the photovoltaic distributed generation units (PV-DGUs) is presented. Secondly, the power quality problems caused by PV-DGUs in the power systems and the international power quality standards related with the systems containing PV-DGUs are investigated. Finally, the power quality mitigation methods have been detailed for the systems with PV-DGUs.

“…In the past decade, a large number of research has focused on how to make DVR work more efficiently and at a lower operation cost, mainly aimed at DC energy storage [8,9], the topological structure [10][11][12] and the compensation schemes or control strategies of DVR [13][14][15][16][17], etc. However, the bulk of current literature on DVR has focused chiefly on the main grid, and there has not been a similar extensive body of literature on the analysis and synthesis of DVR in Microgrids.…”

-A Dynamic Voltage Restorer (DVR) model is proposed to eliminate the short-term voltage disturbances that occur in the grid-connected mode, the switching between grid-connected mode and the stand-alone mode of a Microgrid. The proposed DVR structure is based on a conventional cascaded H-bridge multilevel inverter (MLI) topology; a novel composite control strategy is presented, which could ensure the compensation ability of voltage sag by the DVR. Moreover, the compensation to specified order of harmonic is added to implement effects that zerosteady error compensation to harmonic voltage in specified order of the presented control strategy; utilizing wind turbines-batteries units as DC energy storage components in the Microgrid, the operation cost of the DVR is reduced. When the Microgrid operates under stand-alone mode, the DVR can operate on microsource mode, which could ease the power supply from the main grid (distribution network) and consequently be favorable for energy saving and emission reduction. Simulation results validate the robustness and effective of the proposed DVR system.

“…To prevent the excessive load being taken by a particular PV cell array or a wind turbine in micro-grids, during the voltage sags, the DVR's have been found to be useful [15,16]. Asymmetrical voltage sags have been found to have a serious effect on the operation of wind generators.…”
