This optimization problem becomes complicated if a group of vehicles as a fleet move along the road. Optimization based on the leading vehicle to generate the fleet speed profile might not guarantee the overall minimum cost of the fleet. In this paper, an optimization algorithm for a fleet of autonomous electric vehicles is proposed using the total cost of the fleet to generate the optimum speed profile so that the overall cost of the fleet is reduced. Maintaining a safe distance with the adjacent vehicles and safe lane changing on a multilane road depends on the accuracy of decision making based on the data coming from the embedded sensors in the autonomous vehicle. Both of those two cases can be satisfied easily if the vehicles are moving as a group on the same fleet speed where the individual speed of each vehicle can be adjusted based on the relative distance with the leading vehicle. An artificial intelligence (AI) based realistic autonomous electric vehicle modeling considering all the route conditions is provided in this paper, and optimization is done for a fleet of two vehicles where the physical models of the vehicles are different from each other. The proposed optimization algorithm shows a reduction of the total cost for the fleet compared to the optimization done based on only the leading vehicle’s cost.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123100761","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}

High power density is more readily obtained by reduce components counts in the power electronic converters. The six-switch converter is one of such converters with reduced component count. With this converter however, there are issues of interdependence of phase voltages, unbalance and increased stresses on the switching devices and DC bus voltage underutilization. This paper presents a discontinuous PWM method that addresses these issues and thereby makes the reduction in switch count without the need to overdesign the switching device rating. An algorithm is presented that ensures independent control of phase voltages. With the aid of three zero vector partitioning parameters, voltages are injected to the reference signals that alleviates the unbalance in the switching stresses of the devices. Moreover, the zero vector partitioning parameters are also used for discontinuous PWM generation. The linear region DC bus voltage utilization is improved with the method. The case of over modulation of the converter is also explored. The over modulation scheme is obtained by the determination of a reference voltage location parameter.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"565 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123069192","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 tri-level min-max-min robust problem is developed which is solved through a column-and-constraint (C& C) generation technique to recast the min-max-min problem into a min master problem and a max-min sub-problem. Unlike previous conventional dual-based robust models which solved the max-min sub-problem by duality theory, this study employs block-coordinate decent (BCD) technique to solve it, using first-order Taylor series approximation of the sub-problem. The benefit of such approach is that the bidding binary variables can be obtained in the sub-problem as recourse decisions after uncertainty realizations which results in considerably more practical and realistic bidding solutions. This was not applicable in previous dual-based robust models due to the lack of tractability of a dualized mixed-integer model. Another advantage is that the linearization of the dualized inner problem is avoided as Lagrange multipliers are eliminated in this study which results in a more moderate computational time. In addition, it is possible to consider different buying/selling bids for the model as bidding binary variables are modeled in the sub-problem. A comprehensive case study as well as a post-event analysis are developed for an energy hub to illustrate the optimal bidding decisions and compare the effectiveness of the proposed model with conventional dual-based models.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114669536","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}

These devices not only make volume reduction possible by increasing the electric breakdown field but by reducing the size of the inverters’ passive components due to high switching frequencies. For hard switched converter topologies like the voltage-source-inverter (VSI) this increase in switching frequency also presents it’s own challenges. This is due in part to the necessary fast rise and fall times of the output voltage. This in turn can cause overvoltages at the terminals and stress the insulation system of the driven machine and lead to additional losses because of stray capacitances in the cable connection between machine and inverter. These problems may be addressed either by placing an LC-filter between the VSI and the electric machine or by the use of the increasingly popular current-source-inverter (CSI) topology. Both possibilities come at the cost of additional passive components. This paper compares the volumes of these components for a VSI with an LC-filter and a CSI for a three-phase 400 V, 10.6 A, application.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127086074","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}

This charger in AC-DC conversion stage has an inherent tendency to produce low frequency voltage ripple in both DC-link and split DC-link capacitor voltages. Therefore, bulky high valued electrolytic capacitors are adopted to absorb these low frequency capacitor ripples. Replacing these electrolytic capacitors with low valued film capacitors, results in poor input power quality. Therefore, this paper presents a control strategy based on modified unit-template control with reduced DC-link capacitance value to achieve improved input power quality without using any additional active/passive components. In modified unit-template control, the harmonics information of the grid current is feed-forwarded into the unit template to achieve unity power factor operation and reduced grid current THD. Furthermore, to reduce the influence of double frequency component on EV current/voltage, a DC-link feedforward control is implemented in DC-DC stage. Finally, the effectiveness of the solution presented in this paper, is verified by simulation and experimental results.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127219387","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 well-proved concept is based on the discrete realization of the Ampère´s law using a circular array of magnetic field sensors. Depending on the linear operating range of the magnetic field sensors the radius of the circular array has to be chosen, leading to large dimensions for high current values. This paper presents a novel approach to build a compact wide bandwidth current sensor based on the combination of tilted tunnel-magnetoresistance sensors and a Rogowski coil. The used tunnel-magnetoresistance sensors are characterized and show an increased linear range in the a current sensor application if they are tilted. In addition, the sensor sensitivity is varied with the tilt angel. A novel current sensor concept based on tilting in combination with repositioning the magnetic field sensors is presented. This concept offers the opportunity to reduce the size of state-of-the-art current sensors based on magnetic field sensors significantly. The proposed concept is verified in a current sensor prototype and the DC current linearity, the dynamic behavior as well as the signal-to-noise ratio is characterized.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124787900","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}
