“…From the inductance value standpoint, it has a much smaller L 1 value and slightly larger L 2 value; however, the overall inductance and manufacturing cost decrease significantly. During the simulation process, the resonant frequency of the LCL filter with every combination of L 1 and L 2 is generated with (8). Only the combinations which meet the requirements of (9) are kept.…”

Grid-connected voltage-source inverters (VSIs) have evolved over the past years for the interconnection of renewable energy sources with the grid to satisfy the increased electrical load demand and utilize clean carbon-free energy. However, VSIs suffer a significant drawback of switching harmonics caused by the inverter switches. To reduce the amount of current distortion injected into the utility grid and meet harmonic constraints as defined by power quality standards, an LCL filter is often used. Although extensive literature describes assorted design procedures for an LCL filter, all these methods cannot guarantee an optimal solution, because no direct mathematical function between the LCL filter parameters and the total harmonic distortion (THD) exists. Presented in this paper is the application of an evolutionary annealing–simplex method to select the inductance values in the LCL filter. This method is compared to other methods previously presented in the literature: a systematic method and an inductance grid-search method based on a calculated distribution of total harmonic distortion for various inductance values. The goal is to select the smallest overall inductance values to ensure lower manufacturing costs while maintaining the filter performance. Simulation and experimental results verify that at least a 40% reduction in overall inductance can be achieved with the proposed method while simultaneously guaranteeing the filtering performance.

“…Indeed control methods can be mainly grouped in two major classes, namely control system with inverter-side current feedback (ICF) and with grid current feedback (GCF). For each class, resonance frequency border limits have been established, as expressed in (21) for the ICF control method, and in (22) for the GCF one [24]. (16)…”

“…LCL filter design had been widely reported in the literature, for rectifier applications [14][15][16] for solar rooftop [17], for high power voltage source converters [18], for DC traction station [19] and also for BESS [20][21][22]. Generally, filter design and sizing is conducted in parallel with control synthesis and new methods are proposed to improve damping [23,24] and stability under different grid conditions [25][26][27][28][29][30].…”

This study presents an improved method to design passive power filters for a battery energy storage system operating in grid connected and islanded modes. The studied system includes appropriate controls according to the selected mode. The global system is composed of two power converters a DC-DC converter and a three phase four wires DC-AC converter. The passive power filters to be designed are the battery inductance, the neutral filter and the LCL filter. Conventionally filter design methods are performed considering only one operating mode parameters. This paper proposes an analysis of the design approaches reported in the literature for each mode separately and then provides a step by step design procedure taking into account constraints of each operation mode. The design is performed based on steady state equations for each mode. An overall system simulation with PSIM software has been developed. Simulation results illustrate the effectiveness of the investigated filter design.
