“…The issue of power quality is one of the main challenges in energy delivery to the consumer. This parameter can be improved by using updated control methods [4][5][6][7][8][9][10]. The drawback of the methods presented in the mentioned references in comparison with the proposed method is as follows; Power droop control method is used to improve the power quality of the grid in [4,5].…”

The purpose of this paper is to study the harmonic behavior of hybrid microgrids (MGs). To achieve the desired goal, a modified active power filter (MAPF) and a power filter compensator kit (PFCK) modules have been used to improve the harmonics of the AC part of the system. The main challenge and feature of this research is the optimization of MAPF and PFCK controller gain coefficients hierarchical, using Harris hawk optimization (HHO), grasshopper optimization algorithm (GOA), artificial bee colony (ABC), and differential evolution (DE), respectively. Following, this technique was applied in the three control loops including, voltage and current harmonics, and system controller error to reduce the range of the mentioned harmonics to the permissible range. The method will be interesting considering that the PI and PID tuning is based on parallel feed‐forward. The programmed objective functions include the three components current THD, voltage THD and controller error hierarchically. From the point of view of the MGs hierarchical control, the method presented in this study will be implemented in the second level of hierarchical control. In order to improve the operation of the DC part of the grid, a boost converter module (BCM) has been introduced in the form of a new synchronization scheme. The output of the simulation shows the reduction of the harmonic amplitude of the system by the mentioned modules.

“…However, the controller system presented in this study is comprehensive. To improve the power quality, a multi-objective control method has been used in [9,10]. Based on the adaptive control in the hybrid MGs, the desired method is an effective technique due to the multi objective type.…”
