Storage technologies are essential for preserving the renewable grid power balance between generation and consumption. In this research, a solid-state transformer (SST) based T-type multilevel inverter (MLI) is proposed for the medium/high voltage integration of large-scale battery energy storage (BES). For any turn ratio, the proposed SST-MLI generates 25 levels with fewer switching devices and SSTs. A novel dynamic phase shift controller (NDPSC) is also being developed for the proposed BES system. The NDPSC controller regulates active and reactive power by maintaining the battery's health. The NDPSC controller uses two gain control factors tuned to produce a fast response without overshooting. The proposed battery storage system's dynamic behavior is simulated in MATLAB/Simulink for various active and reactive power variations and experimentally validated in a low-power laboratory prototype system.

This paper deals with the design and the control of multiphase interleaved bidirectional DC-DC Converter. This converter is used for Electric Vehicle (EV) applications to convert and increase energy storage system voltage from low side voltage to high side voltage, which is necessary to feed the inverter used to drive the traction motor. The proposed converter can be used to connect the energy storage system to the smart grid. To increase the performance of high side voltage and to have equal sharing of the load current in each converter module a Fuzzy sliding mode control is proposed. The control method is tested by simulation for the case of 4 interleaved bidirectional DC-DC Converter associated with the three phase inverter coupled with a 3 phase induction motor. The simulation results proved the robustness of the proposed control method under some disturbances.

“…Many modulation techniques have already been developed for MLI such as those derived by Sinusoidal Pulse Width Modulation (SPWM) such as Phase Shifted PWM (PS-PWM), Space Vector Modulation (SVM) [15,16,17,18], Analytical Selective Harmonic Elimination [19,20]. Some of them are nonlinear methods, such as hysteresis control [21,22], sliding mode control [23] and others [24,25]. In classical SHE approach, the switching angles are the unknowns of the problem [26].…”

This paper proposes a selective harmonic elimination technique for medium and high power three phase cascaded H-bridges l-level inverters at fundamental frequency. Compared to other SHE methods, it is capable to delete more harmonics from the output voltage waveform and to provide lower total harmonic distortion values. A mathematical proof is given to demostrate that undeleted harmonics are only those of order n = 2k (l + r) ± 1, k = 1, 2, . . ., where r is an integer parameter that assumes the values −2, −1, 0, de ning three di erent sets of switching angles, provided within the whole range of modulation index. Proposed method assumes the availability of di erent dc voltage sources and pulses patterns, de ned for the three sets of switching angles. Simulated results are shown to con rm the validity of the proposed procedure. For l = 5 and l = 7, obtained results have been compared with those obtained with a conventional SHE technique at the same conditions. Very good performances, in terms of number of deleted harmonics and THD, are observed when r = 0, moreover, in comparison with classical SHE, proposed method o ers reduced computational complexity because it does not require the solution of non linear equations.
