The trend towards development of More Electric Aircraft (MEA) has been driven by increased fuel fossil prices and stricter environmental policies. With breakthroughs in power electronic systems and electrical machines, the targets of MEA to reduce the aircraft mass and drag, thereby increase fuel efficiency, and reduced environmental impact are gradually realized. To meet the increasing demand of electric power on MEA, an advanced power generation architecture (APGA) is investigated in this article. In the APGA, the engine driven parallel connected generators feed power to a common DC bus, and a back-to-back (B2B) converter is used for electrical power transfer between the engine high-pressure (HP) and low-pressure (LP) channels. APGA has the benefits of increasing compressor surge margin and improving generation center overall performance in the aspects of stability, fault tolerance and power density. The APGA is modelled and built in MATLAB/Simulink environment while validation is performed under several operating scenarios.

The large use of electrified aircraft vehicles requires the development of high performance and reliable electric drives. Furthermore, fault tolerant performance plays an important role and control strategies for common faults inherent in the application should be developed. The paper refers to the use Surface Permanent Magnet Synchronous Motors (SPMSM) for the electric propulsion of unmanned aerial vehicles. A numerical approach is proposed for the analysis of the effects of an imbalance of the propellers on the operations and features of the used motors. The results obtained are compared with those deriving from conventional types of eccentricity.

The increasing concern for the environmental impact imposed by the aviation industry shifted engineer and investor interest from conventional combustion engines towards developing electric propelled aircraft designs. These electric aircraft not only comprise a different propulsion system from their conventional market counterparts but also cooling and electrical systems, which can lead to novel aerodynamic solutions. Therefore, the traditional assessment of electric-powered concepts cannot be purely based on aircraft performance parameters inherently influenced by engine type and propulsion system, such as range and/or endurance. Consequently, this paper will focus on developing a new computational tool to compare aircraft performance. This tool introduces an alternative method for comparing aircraft by thoroughly selecting and evaluating characteristic parameters into a cluster of custom metrics, which provide further information and a new perspective into aircraft performance and handling characteristics. Finally, two general aviation aircraft designs, the Evektor SportStar and the Evektor EPOS, are compared against each other. The investigation provides insight into aircraft performance and handling characteristics highlighting both designs' strengths and potential areas for improvement

This work proposes an optimal power management strategy for shipboard microgrids equipped with diesel generators and a battery energy storage system. The optimization provides both the unit commitment and the optimal power dispatch of all the resources, in order to ensure reliable power supply at minimum cost and with minimum environmental impact. The optimization is performed solving a mixed integer linear programming problem, where the constraints are defined according to the operational limits of the resources when a contingency occurs. The algorithm is tested on a notional all-electric ship where the ship's electrical load is generated through a Markov chain, modeled on real measurement data. The results show that the proposed power management strategy successfully maximizes fuel saving while ensuring blackout prevention capability.

Long recharge times are one of the main challenges in providing a seamless experience for users of electric vehicles (EVs) during long trips. Recommender systems play a crucial role in optimizing the recharge process and in providing a better overall experience, as witnessed by a number of solutions presented in the literature. Most of these works, however, focused on minimizing waiting times by suggesting where and when to recharge the EV, leveraging for example historical demand patterns and/or real-time information. In this work, we tackle the problem from the different - and complementary - perspective of suggesting relevant and tailored activities users can perform to make the most out of their EV recharge times. To this end, we present a novel recommender system that leverages open data from the OpenStreetMap project and uses a specifically-trained neural embedding model to capture the semantic relationships between user preferences and nearby available activities and Points of Interest (Pois). The recommender system, whose implementation we make freely available for interested researchers and practitioners, provides personalized recommendations to users based on their preferences and past behaviour. We assessed the effectiveness of the proposal by conducting a study involving real users with different backgrounds, and the results showed that the proposal is effective in providing relevant and personalized recommendations to users, during recharge times.

DC microgrids represent an interesting opportunity for shipboard power system applications, where the integration of dc-interfaced resources is needed. However, maintaining system stability becomes a major challenge in the presence of constant power loads, which exhibit a negative incremental resistance behavior. This work is focused on developing an equivalent linearized model of a DC microgrid, composed by a DC-DC converter used to interface a DC source, such as a battery, with a main dc-bus supplying a constant power load. The state space averaging technique has been employed to develop an unified continuous model of the system under study. The model is then linearized to allow the tuning of regulators and ensuring system stability. Finally, real-time simulations are exploited to validate the proposed methodology.

This paper proposes a novel bidirectional CLC-T resonant immittance converter with a modified secondary for electric vehicle battery charging applications. The proposed converter has inherent constant current (CC) / constant voltage (CV) charging characteristics and is operated only at the resonant frequency. The first harmonic approximation (FHA) technique is used to design the proposed 3.3 kW, 400 V input, 320–420 V output resonant immittance converter. The converter performance at steady-state in charging and discharging operation modes is validated using PSIM simulation. In charging mode, the converter delivers constant current output till the battery reaches the rated voltage. Beyond that, it delivers constant voltage output with decreasing current. The resonant tank is equivalent to CLC-T and CL in CC and CV modes. All the switches attain zero voltage switching in charging and discharging operations. The circulating losses are drastically reduced, which increases the efficiency of the proposed converter as it is operated only at the fixed resonant frequency. As no modulation technique is involved, the complexity of the controller implementation for CC / CV charging is eliminated.

In the context of the decarbonisation of waterborne transport, hybrid-electric propulsion systems play a key role. In this paper, a database of nine hybrid passenger ships for inland transports is built and analysed. The ships are all already operating or under construction. In particular, focus has been made to the increase in lightship weight, quantifying the weights of the hybrid systems including required auxiliary systems fitted onboard. Some considerations are finally given for the most relevant auxiliary systems to be installed on board hybrid electric boats, which are the cooling and fire-fighting systems.

The guidelines of the Green deal, the European plan to eliminate emissions by 2050, provide for a reduction of CO2 emissions by 55% by 2030, a stop to the sale of petrol and diesel vehicles from 2035, more car charging stations electricity in Europe (at least one every 60km) and the production of energy from renewable sources by 40% by 2030. Due to the climate neutrality that is desired to be reached by 2050 through the European Green Deal, the number of sold EV is constantly increasing along with renewable energy sources (RESs) share in local consumption. Due to the increase in EV sales, it is necessary to consider the installation of EV charging systems with a possibility to supply the EV load with RESs. however, the transition from a fossil fuel fleet to a predominantly electric one involves a whole series of problems that must find a solution. First of all the current inadequacy of the charging infrastructure. In all of Europe there are only 226,000 refueling points for electric cars and 7 out of 10 are located in Germany, France and the Netherlands. In this work the operation of a University Campus that has a smart grid composed of RESs and have the possibility to be a prosumer is analyzed along with the situation of using an EV charging system. The use of RESs along with EV and act as a prosumer contributes to the reduction of the pollutant emissions and thus contributes to reaching the target set by the European Green Deal Package.
绿色协议的指导方针，即欧洲到2050年消除排放的计划，规定到2030年二氧化碳排放量减少55%，从2035年起停止销售汽油和柴油汽车，在欧洲增加汽车充电站(至少每60公里一个)，到2030年可再生能源的生产达到40%。由于欧洲绿色协议(European Green Deal)希望到2050年实现气候中和，电动汽车的销量不断增加，可再生能源(RESs)在当地消费中的份额也在不断增加。由于电动汽车销量的增加，有必要考虑安装电动汽车充电系统，为电动汽车负载提供RESs。然而，从化石燃料车队向以电力为主的车队过渡涉及一系列必须找到解决方案的问题。首先是目前充电基础设施的不足。在整个欧洲，只有22.6万个电动汽车加油站，其中10个加油站中有7个位于德国、法国和荷兰。在这项工作中，分析了一个拥有由RESs组成的智能电网的大学校园的运行情况，并分析了使用电动汽车充电系统的情况。将再生能源与电动汽车一起使用，并作为产消费者，有助于减少污染物排放，从而有助于实现欧洲绿色交易一揽子计划设定的目标。

Greener electrified transportation is increasing in popularity while many questions remain in the usage abilities of the electric vehicles. Currently, one of the greatest challenges in the usage of electric power is in battery charging. In comparison to fossil-fuel-based engines that can be refueled in minutes, the charging of an electric battery can consume considerably more time. Different solutions to energize the electric vehicles have been proposed, however the holistic evaluation of the practical feasibility remains relatively unexplored in different solutions. This paper discusses recent development and key aspects and their impact on heavy transportation logistics. The results illustrate a comparative analysis about different energizing solutions' impact on logistics processes in two supply chain cases. The contribution of the paper allows a holistic view of different charging solutions and their suitability for road logistics supply chains, thus enabling better management of the transformation towards the possibility of using electrified logistics.
