“…The output results indicate the proper performance of the above system [11]. To cope with harmonic distortions in the power grid and especially MGs, numerous harmonic compensation approaches are presented in the literature [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. For harmonic mitigation, two elements, active power filter and super capacitor, are investigated in [12].…”

“…Furthermore, the HPQC mitigates grid side unbalance and other harmonics in a co‐phase supplied system simultaneously. [26] presented a new method for equitable distribution of the harmonic compensation cost of the network among the harmonic sources based on the harmonic contribution matrix. Studies are evaluated on the IEEE 14‐bus network and Isfahan regional electrical power network in Iran.…”

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.

“…Some scholars built an equivalent circuit model based on the structure of CVT itself, and the equivalent models constructed were basically similar, and analyzed the related factors causing errors in the transfer ratio of CVT [9]. Some circuit models built by scholars do not consider some parameters of the intermediate transformer, so it is impossible to accurately know how these parameters affect the harmonic transmission characteristics of CVT [10]. Foreign research on transformers started relatively early.…”

With the development of industry 4.0, new energy generation, electric vehicles and high-speed railways, the harmonic pollution problem of power grid has become more and more serious. The comprehensive treatment, responsibility division and cause analysis of power grid harmonics have become extremely urgent. This paper mainly studies a kind of artificial harmonic measurement method. In this paper, linear neural network is introduced into harmonic detection of power system because of its simple structure and small computation. A method based on the approximation of the 5, 7, 11 and 13 harmonics of CVT and neural network is studied to predict the transfer coefficients of each harmonics of CVT in the field. Simulation results show that the detection effect of the proposed method is superior.
