Selective Harmonic Elimination Pulse Width Modulation (SHEWM) can eliminate selected low order harmonics by solving nonlinear transcendental equations to obtain the switching angles in advance and achieve precise harmonics control. However, when solving nonlinear equations, the convergence rate and solution accuracy of the existing intelligent algorithms for multilevel inverter SHEPWM will decrease with the increase of the number of switching angles. In this paper, an improved hybrid PSO-TS algorithm (IPSO-TS) is proposed for switching angle selection in PWM inverter. In the proposed IPSO-TS algorithm, both the PSO algorithm and TS algorithm are improved respectively to enhance their convergence when calculating multiple switching angles. Also, these two improved algorithms are combined to obtain the hybrid algorithm IPSO-TS, in which PSO is used to provide global search capabilities, and TS is used to increases the accuracy of solutions. Simulations are carried out using MATLAB/SIMULINK environment to demonstrate the better convergence of the proposed algorithm compared with the other existing methods. Moreover, the simulation results are further verified by experimental results.

“…The advantages of the suggested inverter were better operating efficacy, decoupled controlling, and reduced leakage current. Liu et al (2019) recommended a distribution control strategy with hybrid energy sources for avoiding fault tolerance. Here, the fault tolerance was attained by the use of redundant converter and bypassing the faulty converter.…”

The solar Photovoltaic (PV) systems have gained a significant attention due to its easy implementation and availability. In which, the proper energy management should be mainly concentrated for a successful PV power utilization. In the traditional works, various controlling techniques have been developed for reactive power compensation. But, it lacks with the issues related to reduced system performance, increased loss, and high harmonics. To solve these issues, this paper aims to develop a new controlling methodology, named as Synthesis Segmental Multilevel Converter (SSMC) for reactive power compensation in a three phase grid systems. Initially, it extracts the maximum power from the solar PV systems by using an Enhanced Perturb and Observe (EPO) method. The panel separation is done and the three phase power input is given to the SSMC converter, where the synchronization and switching pulse generation processes are performed. During synchronization, integrated techniques such as Proportional Integral (PI), Fuzzy Logic Controller (FLC), and Improved Artificial Neural Network (IANN) techniques are utilized to maintain the voltage, magnitude and phase angle in a same level. Consequently, the Inductance Capacitance (LC) filtering technique is applied to reduce the harmonics distortion in the signal. After that, the Park transformation is used to perform the dq0 to abc transformation, which is implemented for reducing the high volume of error. Finally, the error free signal is fed to the three phase grid system with reduced harmonics also both the simulation and analytical results have been taken for analyzing the performance of the proposed technique.
