LC filters are used between a five-phase two-level (FPTL) voltage source inverter (VSI) and a five-phase induction motor (FPIM) to minimize high-frequency losses in the motor, and thus improves the drive performance. It also reduces the high dv/dt at the motor terminals by supplying five-phase sinusoidal voltages. However, this impacts the closed-loop control of the FPIM drive due to sustained resonant frequency oscillations, which destabilizes the drive on certain operational points. Various continuous and discontinuous high-frequency space vector pulse width modulation (SVPWM) techniques are proposed in this paper with detailed analysis. An improved current ripple prediction method is also applied to dampen the resonant frequency and enhance the capabilities of the FPTL FPIM drive. This system is more capable of stable operation without using any auxiliary circuit or high-frequency sensor. Drive stability is tested and verified under different test conditions by simulation as well as experimental results.","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128722687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A unit-template based model predictive control (MPC) is implemented to improve power quality and reliability of the distribution network while charging an EV battery. The MPC approach in this paper, consists of three steps: The first step is an optimization problem i.e., current-control in MPC, the second step is the design making step regarding weighting factor and the third is the fault detection and action control. Further, state of charge balancing is also achieved using MPC to charge/ discharge all split battery storage units at same rate.

However, such existing works lack a robustness guarantee in the presence of fundamental frequency fluctuations. In this paper, a multi-band-stop filter is designed based on the UDE algorithm to reduce the total harmonic distortion (THD) of inverter's output voltage and also to provide the robustness against fundamental frequency fluctuations by modifying the values of output impedance at relevant frequencies directly.

In the event of grid outage, the system is made to operate in a standalone mode (SM) and the VSC control shifts to the voltage control mode. In addition, the load demand is met without any interruption and the surplus solar generation is used to charge the SB using a bidirectional DC-DC converter (BDC). Furthermore, the SB supplies the load demand even under the combination of grid outage and disrupted solar power generation.
