The fast-charging infrastructure interfaced with the utility grid is the mandatory requirement to promote EV adoption aggressively in the world. However, fast charging inversely impacts the grid in terms of injected harmonics and degrades the grid's power quality, demanding careful evaluation to protect the grid consumer interest. Targeting the power quality shaping, the presented work in this paper describes the model of a grid interfaced fast EV charging station. The charging station consists of an active front-end rectifier (AFER) connected to the grid through filter inductance. The output of AFER is connected directly to the DC bus, where EVs get connected through battery chargers. The AFER has operated in closed-loop control with inner current control (constant current control with power factor correction) loop and outer DC voltage control loop. The efficient controller with AFER is responsible for delivering the DC power to the battery at improved power factor and power quality. The proposed control technique efficacy is validated using MATLAB simulation by charging the battery in constant current (CC) and constant voltage (CV) mode.","PeriodicalId":161541,"journal":{"name":"2022 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125345667","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}

Submodule (SM) capacitor voltage control of the MMC is the major challenge in improving the efficiency and reliability of the MMC system. Therefore, a model predictive current control (MPCC) scheme is developed to balance the SMs' capacitor voltage and supply the power generated by the renewable energy sources to load and the utility grid. In the ISM, model predictive voltage control (MPVC) is developed to achieve constant voltage across the load terminals and control the SMs' capacitor voltage. The developed MPC techniques estimate the future behavior of control variables and uses a cost function to produce optimal switching sequence for the MMC. Thus, in comparison to the classical d-q frame control, the developed MPC techniques avoid the use of pulse width modulation schemes, proportional integral controllers and rigorous tuning efforts. Moreover, for seamless transition between ISM to GCM and vice-versa, a phase-locked loop (PLL)-based seamless transition sequence is devised. The performances of the MPCC and MPVC are validated against the conventional d-q control via simulation results under different operating conditions.","PeriodicalId":161541,"journal":{"name":"2022 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123808934","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}

The capacitor voltage is balanced in open-loop by implementing multicarrier pulse width modulation (MCPWM) technique. Furthermore, water pumping system is realized with a single phase induction motor (IM)of 1.4KW rating. Stable operation of the said motor is established by integrating close-loop V/f strategy with modulation technique of solar inverter. For this work solar panels of 1.6KW are incorporated to design the PV system. Maintaining optimum performance of any solar powered drive is a major challenge due to unpredictable nature of environmental conditions that effects the power generation capability of PV panels extensively. To address this issue a topology combining battery pack as well as solar panel is proposed as a single DC source of the packed-U cell. This increases the overall reliability of the system. The battery pack is integrated with the solar inverter through a bidirectional DC/DC converter to enable its charging as well as discharging depending on the available power output of the photo-voltaic (PV) arrays. The PV panels are connected with the DC link capacitor of the battery unit through a unidirectional DC-DC converter.

Various configurations of these converters are reported in the literature. The major gap which is observed in the reported converters is that these converters are available either in isolated or nonisolated configurations. The converter which provides the isolated and nonisolated dc output is not available. In this paper, a Single Input Boost Hybrid Interlink Converter (SIBHIC) is proposed which includes two dc-dc boost converters. These converters are supplied by an input dc source. The nonisolated dc output is available across these boost converters. Complementary operation of the switches connected in adjacent boost converter leads to the production of high-frequency ac output voltage. These high-frequency output voltages can be rectified using a bridge rectifier including fast recovery diodes and can be used as an isolated dc output voltage. In this way, the proposed converter includes two nonisolated dc output ports and one isolated dc output port. Further, the complementary action of switches included in the adjacent dc-dc boost converters leads to a reduction in the magnitude of ripples in the source current. This leads to a reduction in losses and enhances the efficiency of the converter. Various operating modes, design method used to select various elements, and evaluation of the efficiency of SIBHIC is included in this paper.

The effects of faults on the Microgrid are analyzed and required control measures are implemented to stabilize the turbine speed as well as to improve the quality of voltage at AC load bus. The controller of the existing maximum power point tracker (MPPT) is modified to limit the turbine speed during the fault(s). Distribution static shunt compensator (DSTATCOM) is further considered at AC load bus to provide the support for stabilizing the voltage during faults. Its novel control is presented to maintain the PCC voltages within allowable limits after occurrence of fault. Moreover, the connected DSTATCOM can also compensate for the reactive power demanded by the load. Further, with the help of DSTATCOM, torque pulsations induced in the generator due to unbalanced load are reduced. Fuel Cell and Electrolyzer are incorporated into the system to supply the reliable power at the load bus. The performance of Fuel Cell and Electrolyzer is also evaluated under the condition of fault.

These challenges include nuisance trips due to intolerably high communication delay and loss of fault sensitivity in the event of communication link failure. Also, to incorporate potential mal-operation in the event of CT saturation, line charging current and marginal delay, higher restraining zones are set for line differential relay. Hence, sensing evolving faults with higher impedances is difficult with the differential principle. Considering these limitations, a novel Machine Learning (ML) based approach is proposed in the article to assist differential relay in detecting high impedance faults and allow larger restraining zones. The proposed ML-based relay also acts as a backup in case of communication link failure. The ML models used such as Decision Tree, Support Vector Machines, and K-Nearest Neighbors also adapt their training to detect each fault. To improve computation speed and reduce calculation burden, a novel ensemble of dimensionality reduction using PCA, Linear Regression, and Pearson Coefficient is presented in the article. Data for ML models are obtained and validated using MATLAB and PSCAD.

The proposed article is on multiport output series resonant interleaved DC-DC converter with unidirectional power flow capability of different ports with particular voltage level. Having a multiport structure reduces the requirements of components resulting the cost and volume of the system decreases in comparison with the same number of individual chargers.

The integrated multifunctional DP-OBC can simultaneously utilize two power sources for charging the battery storage system (BESS). When at a standstill, the electric vehicle (EV) BESS can be charged simultaneously via multiple sources, i.e., AC grid plus rooftop solar PV system or DC source plus rooftop solar PV system.
