Grid modernization, transportation electrification and alternative energy technology applications are interconnected with electric vehicle grid integration (EVGI) to form the energy internet. The EVGI management strategies incorporating both charging and discharging is one of the most common research problem in this area. It becomes more complicated when renewable energy is added as a source and implemented in commercial scale. In this article, a community based commercial electric vehicle (EV) fast charging station with vehicle to grid (V2G) power supply capability is proposed. The charging station load is supplied by photovoltaic (PV), energy storage system (ESS), EV discharge power and the grid. Dynamic pricing, user behavior based EV load model and grid loading conditions are considered in the model. For optimum sizing of the components, HOMER software provided by National Renewable Energy Laboratory is used. A non cooperative Stackelberg game theory is proposed for energy management. The results are compared with a conventional sequence based control algorithm.The proposed algorithm shows lower cost of energy (COE) for EV charging, and have surplus income from system to grid (X2G) energy sales. Thus, from the charging station perspective it can generate profit, also it can be beneficial for EV owners if they can manage their charging and discharging time according to the announced charging/discharging prices.

Global cognizance for a green environment will embark on the rising demand for Plugin Electric vehicles (PEV) in the upcoming years. In this article, an online power management scheme (RTPMS) for a solar power battery-buffer grid-connected charging facility in an educational work area is developed. This algorithm contributes to lessening the overall diurnal price of recharging the PEVs, alleviating the influence of the charging station on the power grid, while participating in shaving the rise of the load curve. The understudy paper sheds the idea of quick charging of PEV integrated with energy storage stacks, photovoltaic systems and at the least demand with the power grid subject to constraints scenarios. Forecasting and statistical parameters are considered in the RTPMS to model the many uncertainties encompasses such as the photovoltaic power, PEVs arrival-departure period, and the energy present in their car batteries during their entrance at the station. The paper demonstrate maximum profit acquired by fast electric station besides lessening the overloading on the power grid with the execution of resilient RTPMS. The efficacy of the proposed supervisory rule-based method is stamped through assigning different assignments through MATLAB code editor.

The integration of renewable and clean solar energy through photovoltaic (PV) technologies is increasing rapidly all over the world. Well-planned and maximum usage of sunlight elevates the efficiency of PV panels. Due to the different geographical conditions of the earth, solar radiation is not the same for all locations. Optimum tilt angle helps the solar panels tap the highest solar irradiance, consequently, provides maximum PV electricity. In this work, a method of determining optimum tilt angle is presented, which is implemented in MATLAB environment. Eight sites of Okinawa prefecture of Japan are selected to measure the optimum tilt angles, which render the highest incident global solar radiation over the year. Results show that optimum tilt angle ranges from 1 degree to 58 degrees in Okinawa. It is also observed that optimum tilt angle based PV panel orientation obtains a significant increase in solar radiation on its tilted surface.

In Smart Grid, Phasor Measurement Unit (PMU) is the most significant tool which provides voltage and current phasor that are synchronized in absolute time reference using global positioning system commonly known as Synchrophasor. This paper presents the methodology for Optimal Placement of Phasor measurement unit (OPP) using Binary Linear Integer Programming (BLIP) with binary decision variables (0, 1) for minimizing the cost of installation to provide complete observability of the power system under normal and islanding condition. The optimal placement is attained by ranking the solutions using redundancy of the system. In this paper, the placement of PMU is realized with several cases namely conventional flow measurement, with zero injection and without zero injection. The best optimal location is one, a bus with maximum BOI, SORI and redundancy index. The feasibility and effectiveness of propounded method is tested in IEEE 7, 9, 14 and 30 bus system using Matlab R2018 software. The results obtained have shown, the proffered method of PMU placement is fast and more accurate with excellent computational efficiency.

In this study, a method is proposed to minimize the harmonics injected by the electric vehicle (EV) chargers at the point of common coupling using a shunt active power filter (APF). The proposed APF utilizes a bidirectional voltage source inverter (VSI). Herein, two different control techniques are implemented to enhance the robustness and effectiveness of the system. First, an effective hysteresis controller is developed to provide the necessary switching pulses for driving the VSI. Then, a hybrid fuzzy proportional-integral (PI) controller is designed to regulate the DC link voltage of the VSI. Furthermore, a positive-sequence synchronous reference frame controller and a low-pass filter are used to estimate and extract the harmonics content injected by the EV chargers at the point of common coupling. Subsequently, various case studies are conducted to evaluate the performance of the proposed harmonics mitigation technique. The simulation results show that the fuzzy PI-based DC link regulation method provides enhanced dynamic control of the DC link capacitor voltage under various operating conditions when compared with those provided by a conventional PI controller. Furthermore, the total harmonic distortion (current) at the source side under various operating conditions can be limited well below the IEEE 5191992 harmonic standard.

This paper theoretically discovers a cutoff behavior of the DC current in twin rectifiers operating in parallel. The formulation of the circuit starts from a single rectifier focusing on its flow-angle equation. The DC output voltage and current formulas are derived in terms of the RF input power and load resistance. We then consider twin rectifiers connected in parallel at the DC output port. When the twins are excited with different RF amplitudes, a specific input power ratio exists whereby the weaker rectifier goes to sleep. We name this behavior rectifier's current cutoff, and the specific cutoff power ratio is theoretically predicted as –13.3 dB. A harmonic-balance simulation and proof experiment are performed at an input frequency 6.78 MHz and power up to 100 W in total. Both simulation and experiment successfully confirm the current cutoff behavior.

This paper reports on the effects of aging on thermal and dielectric properties of unfilled polypropylene and polypropylene nanocomposites containing 2 wt% and 5 wt% of magnesium aluminate nanofiller. These evaluated samples were prepared using a melt blending technique. A hydraulic laboratory press was employed in order to obtain 100 μm thick sample. Two different aging conditions were considered, namely, unaged (as a reference) and aged at 140 °C. The evaluated samples were then characterized using differential scanning calorimetry (DSC) for thermal analysis. Meanwhile, the dielectric strength was determined based on DC electrical breakdown tests. The experimental results show that, aging the samples at 140 °C changed the thermal behavior of all evaluated samples. Specifically, the melting temperature (Tm) increased when the samples were aged at 140 °C. Meanwhile, the DC breakdown strength of unfilled polypropylene reduced significantly after aging at 140 °C when compared to polypropylene nanocomposites.

In this work, TCAD simulation has been applied to study the Power U- shape metal-oxide-semiconductor field- effect transistor (P-island Power UMOSFET) with p-type islands to determine its sensitivity to Single Event Burnout (SEB). In the drift area, the p-type buried islands suppress the strong electric field at the bottom of the trench and prevent SEB. For the appropriate device design, the effect of doping concentration, thickness, length, and position of the p-islands on the breakdown voltage and the threshold voltage is studied. Using optimized parameters for the P-island, the hardened PI-UMOS obtains unchanged electrical characteristics from the standard UMOSFET. The outcome of the SEB simulations shows that the electrical field in the hardened structure is decreased by 60.12% relative to a standard structure and that the survivability of the SEB has also improved substantially by about 30.1%. Hence, Power UMOSFET with P-islands offers high SEB survivability for space and atmospheric applications.

Geomagnetic induced current (GIC) caused by geomagnetic disturbance (GMD) can be a serious threat to a stable electrical power grid operation. GIC that is induced in the earth magnetic field flows through the neutrals of grounded-wye transformers may lead to increasing reactive power consumption which can result to voltage collapse. Therefore, it is important to study the evaluation of this event on the electrical power grid. This paper presents the analysis of GIC modelling and calculation in a 4 bus test case system using Power World Simulator. The value of calculated GIC using Power World are validated and compared with theoretical using nodal analysis method. Based on the study conducted, it is found that the geomagnetic storm magnitude and direction in degrees can affect the GIC values.

The value of calculated GIC using Power World are validated and compared with theoretical using nodal analysis method. Based on the study conducted, it is found that the geomagnetic storm magnitude and direction in degrees can affect the GIC values.","PeriodicalId":6768,"journal":{"name":"2020 IEEE International Conference on Power and Energy (PECon)","volume":"5 1","pages":"194-197"},"PeriodicalIF":0.0,"publicationDate":"2020-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84689783","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}
