“…The PI controller optimized by the genetic algorithm gives 0.89% of the total harmonic distortion (THD) less than 1.97% obtained in [22]. This value of THD satisfies the standard value given by NF C 15-100 and IEEE 519 (T HD <5%) [15], [27], [28]. Figure 12 (a) shows the deference between the proposed method and PI Classique.…”

This paper presents the meta-heuristic and conventional optimizations techniques for the grid connected photovoltaic solar system. The perturb and observe (P&O) and particle swarm optimization (PSO) algorithms are proposed to track the maximum power point (MPP) of the photovoltaic solar system (PVSS). The regularization of the current supplied into the grid is ensured by the proportional integral (PI) corrector whose parameters are generated by the genetic algorithm (GA). The results of these two MPPT methods are compared and showed that the PSO is more efficient than the P&O. The use of GA algorithm to determine PI parameters allowed to obtain 0.89% of total distortion harmonic (THD).

“…From the above results, it is evident that the modular statcom with FLC-based ESOGI can eliminate current harmonics. The comparative study with the existing method clearly indicates that a harmonic distortion in the source current measured by the proposed system is 1.2%, which is below the average THD level obtained by the systems of Kausal and Basak 19 ; Piradhan and Mishra 20 ; Divyalakshmi and Subramaniam 21 ; and Prasad and Akella. 22…”

This paper describes an optimal way to produce and utilize green power with better energy efficiency. The power quality issues in wind energy conversion systems (WECS) are improved by implementing a photovoltaic (PV) based modular statcom. Modular statcom consist of a modular multilevel inverter (MMI). The peculiar feature of the MMI is that it does not need any auxiliary circuit to provide the negative voltage levels. It is inherent in nature. The DC link of the modular statcom is fed from the PV source, battery, and Flywheel. The excess power obtained from PV and WECS is stored in the battery and Flywheel. Continuous power can be supplied to the load without any interruption is an added advantage of the proposed system. A landsman converter is implemented for the proposed PV system to provide regulated and constant DC supply to the modular statcom.An enhanced second order generalized integrator (ESOGI) with fuzzy logic controller (FLC) is employed to extract the source reference current signal and produce gating pulses for the modular statcom. To verify the performance of the PV-integrated modular statcom, the simulation and experimental studies are performed under specific load conditions. Results show that the proposed system with the ESOGI method reduces the current distortions and satisfies the IEEE-519 standards.

“…In some cases, the microgrid can also present resonances at low frequencies, which might result in an undesirable increase of voltage harmonics (Bollen et al, 2017a(Bollen et al, , 2017b. According to Kaushal and Basak (2020), the effect of line impedance on power quality parameters is especially important when the microgrid's status changes from interconnected to islanded mode. As a result, voltage deviations are the main affected parameter.…”

Power Quality in AC Islanded Microgrids: Technical Framework and State of the Art Review

In recent years, operation and control strategies in distribution systems have changed due to the increase in the connection of distributed generation sources (DGs). Small local networks with electricity users and DGs are known as microgrids. These microgrids can operate independently (islanded) or in collaboration (interconnected) with the main network or other microgrids. Some advantages of interconnected microgrids include the reduction of losses, an increase in reliability, and decentralized operation under fault conditions. Nevertheless, when a microgrid operates in islanded mode, its electrical characteristics change and, consequently, the severity of power quality disturbances can increase, as well as their negative impact on electronic devices (loads and DG devices). This paper presents a comprehensive literature review of existing studies on power quality disturbances in islanded microgrids and identifies the most relevant needs for future research on this topic. Detailed information is analyzed to compare the differences between disturbance levels in both interconnected and islanded microgrids. In the case of harmonic disturbances, the impact of the different microgrid configurations is also analyzed.
