“…During the advancement of MG installation, various PQ mitigation methods and control strategies that use optimization algorithms are developed. For instance, the authors in [127] proposed biogeography-based optimization to reduce the harmonics in MG systems to within the required limits. Some optimization methods were used to enhance the performance of custom power devices to mitigate PQ issues in MG.…”

A microgrid (MG) is a small-scale power system with a cluster of loads and distributed generators operating together through energy management software and devices that act as a single controllable entity with respect to the grid. MG has become a key research element in smart grid and distribution power systems. MG mainly contains different renewable energy sources (RESs) that use various technological advancements, such as power electronics-based technologies. However, it has an unstable output, thereby causing different types of power quality (PQ) events. As a result, standards and mitigation methods have been developed in recent years. To mitigate PQ issues due to MG integration, various methods and standards have been proposed over the last years. Although these individual methods are well documented, a comparative overview had not been introduced so far. Thus, this study aims to fill the gap by reviewing and comparing the prior-art PQ issues, solutions, and standards in MGs. We compare the main issues related to voltage sag, voltage swell, voltage and current harmonics, system unbalances, and fluctuations to ensure high-quality MG output power. The new technologies associated with MGs generate harmonics emission in the range of 2-150 kHz, thereby causing a new phenomenon, namely, supraharmonics (SH) emission, which is not sufficiently covered in the literature. Therefore, the characteristics, causes, consequences, and measurements of SH are highlighted and analyzed. The mitigation strategies, control, and devices of PQ issues are also discussed. Moreover, a comparison is conducted between the most popular devices used to mitigate the PQ issues in MG in terms of cost, rating, and different aspects of performance. This review study can strengthen the efforts toward the mitigation and standards development of PQ issues in MG applications, especially SH. Finally, some recommendations and suggestions to improve PQ of MG, including SH, are highlighted.

“…A proposed control scheme consisting of a resonant (R) controller was also designed and presented for a DFIG operating under distorted grid voltage conditions in [15]. Some other researches related to the first and second abnormal problems such as the analysis of voltage faults have been reported in [16][17][18][19][20]. The third abnormal problem is nonsinusoidal rotor voltage injection that effectively reduces the performances of a DFIG [3].…”

“…Therefore, it has become mandatory to maintain the stipulated quality of power as recommended indifferent international standards, e.g. IEEE 1547, IEC, EN, CIGRE WG 36-05, and NRS [2]. Harmonic elimination has, therefore, become a very important issue with respect to the operation of the MGs.…”

This study develops a framework for optimisation of rotor side converter (RSC) switching to eliminate lower-order harmonic injection of a doubly fed induction generator connected to a grid. A biogeography based optimisation (BBO) technique is used for this purpose. Three level inverters operating in either 120° or 180° modes at slip frequency are usually employed for the RSC to reduce switching losses. Non-sinusoidal rotor injected voltages by RSC generates undesirable stator harmonics based on the operating rotor speed. Induced harmonics in the stator are analysed and computed. A modified switching strategy is developed to reduce stator harmonics at different speeds. A BBO-based technique is used to compute the switching angles off-line controlled with minimum injected harmonics at closed intervals of modulation indices. These angles are stored in processor memory for an on-line application using mixed model equations which have low memory usage. Various simulations are executed and supported by suitable experiments with a practical machine for verification of the proposed model which provided satisfactory results.
