“…Therefore, optimizing the THD and SPV Penetration concurrently is a requirement for smooth operations of multilevel inverter-based PDS [9,[13][14][15][16]23,24]. This has motivated many researchers to build various efficient control strategies to mitigate the THD in the generated power to its desired level [9,10,[13][14][15][16]22,[24][25][26][27][28]. Some researchers have focused on inverter switching control, while others applied filters to suppress the harmonics in the power output [10].…”

Integrating a high Penetration level of Solar Photovoltaic (SPV) power in the electricity grid could enhance the system’s sustainability, reliability, and affordability. Nevertheless, at higher Penetrations, the intermittency, non-dispatchable nature of the SPV generation, and the extensive utilization of inverter-based interfaces generate excessive harmonic distortions that damage power system devices and interrupt the smooth operation of the power system. Thus, the severity of the harmonic distortion impacts varies as a function of the degree of the SPV Penetration level in the grid-connected system. Though the problem is highly nonlinear stochastic programming with multiple conflicting power quality criteria, no existing study holistically captures the randomness, the contradictory nature of the objectives, and the grid’s technical limitations simultaneously. This study proposes a novel Monte-Carlo-based Hybrid multi-objective methodology to scale up the Photovoltaic Penetration level with a minimum Total Harmonic Distortion (THD) for multilevel SPV inverters in grid-connected systems without violating the system’s standard operational limitations. Six state-of-the-art Multi-Objective Evolutionary algorithms were implemented and compared using hypervolume indica- tor, execution time, and parametric statistical analysis to obtain a quality solution. The results showed that the Hybrid NSGAII-MOPSO outflanked the rest in terms of convergence, diversity, and execution time. It could be inferred that even under variable weather conditions, this harmonic suppression design approach could accurately optimize the SPV Penetration level and mitigate the THD without degrading the grid’s standard operational constraints. In comparison, the stochastic design technique creates a far more reliable SPV grid-connected system than the deterministic approach.

“…The necessity to lower overall harmonic distortion in an inverter's output led to the development of multilevel power conversion technology (Raj, M. D. et al, 2022). It will later serve as a functional solution to the demand for high-voltage DC bus-driven inverters.…”

This paper deals with the implementation of a reduced multilevel connections (RMC) as Voltage Source Converter (VSC) in Shunt Active Power Filter (SAPF) for harmonic mitigation in Power system. The design mainly focuses on the voltage source converter of SAPF. The developed modular structure produces 9,11,13,15,17,19,21,23,25,27,29,31 output levels using symmetric and asymmetric PV sources. This paper mainly focuses on a robust design of power circuit (RMC) and control circuit (SHE controller) for obtaining required voltage levels. Hence, to design a 27-level inverter, the traditional clamped topology requires 52 switches, the Cascaded H bridge (CHB) topology requires 52 switches and in the proposed RMC only 12 IGBTs are needed to produce 27 level. An added advantage of these topologies are they produce less total harmonic distortion by increasing the output levels. The design includes a comparison of 27-level reduced multilevel connections (RMC) topologies suitable for asymmetric input sources from solar photovoltaics (SPV). Further the loss calculation and the cost analysis are done to make the inverter superior than the conventional topologies. The implementation of RMC with the selective harmonic elimination method mitigates harmonics in the system. The proposed system is modeled using MATLAB/Simulink. An Experimental setup of the suggested SAPF is established and experimentally investigated. A 3 KWp solar PV plant is used to feed the DC input to the developed prototype. Based on the findings, it can be concluded that the suggested inverter reduces the harmonics, compensates reactive power, improves power quality, lessens the components, lessens the size and reduces the cost.
