“…Moreover, unlike passive filters, they do not cause harmful resonances with the power distribution systems. Consequently, the active power filter performances are independent of the power distribution system properties (Abdalla et al, 2010).…”

This paper proposes an intelligent technique-based optimal controller for harmonics mitigation to maintain the power quality in renewable energy source (RES)-based distribution systems. The proposed intelligent technique is the joint execution of both the fractional-order proportional integral controller and moth-flame optimization with random decision forest. In the proposed approach, moth-flame optimization optimizes the dataset of fundamental and harmonic loop parameters such as terminal voltage and direct current voltage present in the hybrid shunt active power filter. The dataset is generated based on the linear and nonlinear load variation and parameter variation of the renewable energy sources, subject to the minimum error objective function. Based on the accomplished dataset, random decision forest accurately predicts the parameters and produces optimized control signals. The proposed technique guarantees the system with less complexity for the harmonics mitigation of the power quality event and hence the accuracy of the system is raised. Then, the proposed model is executed in the Matrix Laboratory/Simulink working platform and the execution is assessed with the existing techniques. The simulation analysis of the proposed approach is tested using the six test cases with various combinations of nonlinear loads. In all the test cases, the performance of various system parameters, such as source current with and without filter, source voltage, hybrid shunt active power filter current, load current and voltage, is analysed. Furthermore, the total harmonic distortion at different load ratings is also examined.

“…On the other hand, shunt APF has been widely used to mitigate the harmonics. It cancels the load-current harmonics and provides reactive compensation to the supply, through the act of injecting equal but opposite harmonic compensating current to the supply [27][28][29][30][31][32][33][34][35][36][37][38]. Shunt APF has the advantage of carrying only the compensation current plus a small amount of active fundamental current to compensate for system losses.…”

Shunt active power filter (APF) method have been used by many researchers as a solution in reducing the harmonics creating by the non-liner loads. Therefore, this research is targeted to design and implement a three-phase shunt APF employing Kalman filter estimator. Conventionally, low-pass filter (LPF) is used to filter out the unwanted DC component of the non-linear load to produce the sinusoidal waveform called the reference current. However, when applying LPF it contributes with the phase shift and high transient at the supply current. Therefore, to reduce these problems, the digital Kalman filter estimator is used to replace the LPF for generating the reference current. Details on the investigation between conventional and proposed methods under simulation based on Matlab Simulink platform and experimental that are made for two types of load, namely, three-phase rectifier with RC-load and three-phase induction motor, are presented. The performance criteria of the shunt APF are determined by the supply current waveform, total harmonic distortion (THD), harmonic spectrum and power quality measurements, which were also obtained by simulation and experimental. In conclusion, by employing Kalman filter estimator for generating the reference current, it reduces the time delay and high transient current at the power supply and, thus, improved the overall THD from 0.1 to 0.42% compared to the LPF.

“…Power quality for the digital economy in a Smart Grid distribution system is a priority which involves various options of quality and price is a priority. Meanwhile, the impact of renewal sources of energy like solar, wind, wave etc., which mainly use power electronic controllers and integrated into the Smart Grid cause increased power quality problems [1]- [6]. A two level voltage source inverter based SAPF to compensate harmonic currents and reactive power in industrial networks was already established [1]- [7].…”

This paper presents a compensating system for the harmonic currents, the reactive power in three-phase distribution system by using a five-level inverter based shunt active power filter (SAPF) connected by a photovoltaic system. A controller based on the p-q theory is introduced for the SAPF. The distribution network which supplies non-linear load and employing five-level inverter based SAPF connected by a photovoltaic system is simulated by MATLAB/SIMULINK software. The performance of SAPF is analyzed by using the proposed control technique on the total harmonic distortion of source current, power factor and reactive power. Besides, it is illustrated by extensive simulation results, the effectiveness of five-level SAPF connected by a photovoltaic system.
