In this paper a direct method to estimate maximum power points (MPPs) in PV arrays subjected to mismatching conditions is presented. The method uses the lossless single-diode model (SDM) which is parameterized using the data of inflection and maximum power points of each panel. The reconstruction of power vs. voltage curve is obtained by one explicit equation, thus avoiding the use of recursive non-linear equations solver. The performance of this technique has been validated in terms of computation time and accuracy by means of the comparison with other existing methods.

A loadability policy established on the basis of the Overhead Transmission Lines (OHLs) static thermal rating is referred to the worst-case conditions (i.e. zero wind speed). Whilst it reduces the potential misoperations, at the same time it implies an underuse of the electrical infrastructures. The transition towards smart grids architectures calls for a reliable exploitation of these assets in order to improve the power system efficient operating. Such considerations are at the basis of the so called Dynamic Line Rating (DLR) paradigm which is incorporated in the smart grid vision. An open issue in this topic is the need to take under control the weather conditions and hence the OHL temperature along the entire OHL length. To overcome the pointed out issue, thanks also to the quick development of Wide Area Measurement System (WAMS) technology, an innovative approach can be pursued. OHL thermal dynamic can be derived from the measurement of the voltage and current synchrophasors at the OHL ends, so overcoming the need of spatially distributed sensors DLR system. It is worth noting anyway that in this case it deals with an average estimate of the OHL conductor temperature and not a punctual one as obtained by using distributed devices. With regard to the described framework, the present paper presents the first experimental findings obtained in an in-field DLR campaign carried out on the Italian power system. A recently proposed DLR estimation algorithm, never applied in reallife WAMS environment, is selected for the purpose. From its response, interesting considerations and valuable modifications to apply to the estimation algorithm mathematical framework are suggested in the work. The fundamental characteristics that the latter needs to have are well posed in evidence. The discussed experimental outcomes are referred to a real-life OHL included into the Italian WAMS monitoring program.
基于架空输电线路(ohl)静态热额定值建立的负载策略指的是最坏情况(即零风速)。虽然它减少了潜在的误操作,但同时也意味着电力基础设施的利用不足。向智能电网架构的过渡要求可靠地利用这些资产,以提高电力系统的高效运行。这些考虑是所谓的动态线路评级(DLR)范式的基础,该范式被纳入智能电网愿景。本主题中的一个开放问题是需要控制天气条件,从而控制整个OHL长度上的OHL温度。为了克服上述问题,随着广域测量系统(WAMS)技术的迅速发展,可以寻求一种创新的方法。OHL热动态可以通过测量OHL两端的电压和电流同步量来获得,从而克服了DLR系统对空间分布传感器的需求。无论如何,值得注意的是,在这种情况下,它处理的是OHL导体温度的平均估计,而不是通过使用分布式设备获得的准时估计。关于所描述的框架,本文介绍了在意大利电力系统上进行的现场DLR运动中获得的第一个实验结果。本文选择了最近提出的一种从未在实际WAMS环境中应用过的DLR估计算法。从它的响应中,提出了一些有趣的考虑和有价值的修改,以适用于估计算法的数学框架。后者需要具备的基本特征是显而易见的。所讨论的实验结果参考了意大利WAMS监测计划中包含的现实生活中的OHL。

The diffusion of distributed electric generation sources is a growing phenomenon, encouraged by the changes in the electric energy market and the concerns about gas emission. Microgrids are composed by different types of generators, several loads and power converters necessary to interface all the microgrid components and the microgrid itself with the main AC grid. This paper presents a new flexible power converter capable of changing its topology by means of static switches so that it can provide different conversion functions using the same hardware. This proposal aims to reduce the number of components, enhancing compactness and simplicity, and resulting in lower equipment costs. The proposed converter is conceived for domestic microgrids, is connected to the AC grid and a renewable energy source (RES) and is configurable as a single-input dual-output (SIDO) converter, providing two different DC voltage levels. After showing all the possible configurations of this converter, the analysis focuses on SIDO, deriving its mathematical model and discussing a procedure to design its elements. The controllability of the SIDO is tested via numerical simulations showing good performance even during fast transient conditions.
由于电力能源市场的变化和对气体排放的关注,分布式发电源的扩散是一种日益增长的现象。微电网由不同类型的发电机、若干负载和电源转换器组成,这些都是连接所有微电网组件和微电网本身与主交流电网所必需的。本文提出了一种新型的柔性电源变换器,它可以通过静态开关改变其拓扑结构,从而在相同的硬件下提供不同的转换功能。该方案旨在减少组件数量,增强紧凑性和简单性,从而降低设备成本。所提出的转换器是为国内微电网设计的,连接到交流电网和可再生能源(RES),可配置为单输入双输出(SIDO)转换器,提供两种不同的直流电压水平。在展示了该转换器的所有可能结构后,重点分析了SIDO,推导了其数学模型,并讨论了其元件的设计过程。通过数值模拟验证了SIDO的可控性,表明SIDO在快速瞬态条件下也具有良好的性能。

The behavior of a magnetic gear which employs rare earth magnets is analyzed; the magnetic gear allows the power to be transmitted by transforming speed and torque. An analytical simplified approach for the analysis of the considered magnetic gear is used in this paper. The approach can be suitable for design aims. The mathematical model is one-dimensional: only the variation of electromagnetic quantities as function of angular position is considered, the permanent magnets are modeled by means of constant currents located at their edges. The resulting magnetomotive force generated by two rotors is modulated by the distribution of the variable permeance due to the difference of the magnetic permeability between the air of the slots and the magnetic material of the pole-pieces. The analytical results are verified by means of a finite element method.

Among single stage, single phase, inverter configurations the Neutral Point Clamped topology is advantaged by its quiet rail switching mechanism, producing negligible common mode currents. However, it requires a double input voltage if compared with a classic full bridge inverter. A modified Neutral Point Clamped, three level, single phase, inverter topology is presented in this paper intended for Thermoelectric Generation Systems applications. The proposed topology owns an inner voltage boosting capability, thus, it can be supplied with an input DC voltage equivalent to that of a conventional H bridge inverter, or even lower. Moreover, it is able to compensate voltage drops caused by variations of the thermoelectric generator operating temperature. Finally, no extra high frequency switching devices are introduced to implement the voltage boosting function.
在单级、单相逆变器配置中,中性点箝位拓扑的优势在于其安静轨开关机制,产生的共模电流可以忽略不计。然而,与传统的全桥逆变器相比,它需要双输入电压。本文提出了一种改进的中性点箝位,三电平,单相逆变器拓扑,用于热电发电系统的应用。所提出的拓扑结构具有内部升压能力,因此,它可以提供相当于传统H桥逆变器的输入直流电压,甚至更低。此外,它还能补偿由于热电发电机工作温度变化而引起的电压降。最后,没有引入额外的高频开关器件来实现升压功能。

A solar panel or module, under different irradiation and temperature conditions, is characterized by its I-V characteristic curve. The evaluation of these curves allows to completely characterize the panel from the performance point of view. As well known, the performance of the photovoltaic (PV) system in terms of generated power depends not only on the photovoltaic panel quality but also on the employed maximum power point tracker algorithms (MPPT). In technical literature many MPPT algorithms have been proposed but a clear method to compare their performances is missing. For this reason a good system for the evaluation of PV technology allowing to test different PV panels with different tracking algorithms in the same environmental conditions could be very useful. In this paper the design and implementation of a system oriented to the characterization of PV systems and to the comparison of MPPT algorithms will be proposed. It allows to measure the characteristic curves of a panel and easily to implement MPPT algorithms in different irradiation and temperature conditions. Experimental tests have been carried out to validate the performance of the system.

The production of large amounts of energy from wind farms is acknowledged to cause problems in terms of both environmental impact (modification of the landscape, large surfaces engaged and possible interaction with avian fauna) and quality of the electrical energy produced (instability of the electric grid, flickers). This paper aims to present a research on the power quality associated with the introduction of wind generation into the Italian electric grid. Specifically, this paper focuses on voltage flicker analysis in transmission grids characterized by the presence of many wind generation. Wind energy conversion systems produce fluctuating output power, which may cause voltage fluctuations and flicker. An in-depth investigation, based on infield measurements data, of the correlation between power quality, in particular flicker, and renewable energy based on wind farm is presented and discussed.

Paper presents power conditioning system that is applied to smart microgrid supplied from renewable energy sources (RES). Usually the microgrid is equipped in Diesel driven synchronous generator that operates with fixed speed and provides demanded power and stabilizes output voltage. However, when the power of the RES is rising the Diesel engine specific fuel consumption is also rising and then Diesel engine efficiency drops. So such a system consumes a lot of fuel what reduces efficiency of the microgrid. Therefore, instead of fixed speed generation set, an adjustable speed generation system is applied. So the topology of the adjustable speed generation system is developed. Paper delivers principle of Diesel engine variable operation that speed is adjusted to demand of power and controlled load torque follows the areas of low specific fuel consumption and then save a lot of fuel in comparison to fixed speed. An example of calculation of fuel consumption by generation units operating with fixed and adjustable speed based on brake specific fuel consumption maps has been made. The calculation confirms that the application of adjustable speed generation systems results in significant fuel savings.
介绍了一种应用于可再生能源智能微电网的电力调节系统。微电网通常配备柴油同步发电机,以固定的速度运行,提供所需的功率并稳定输出电压。然而,当RES功率增大时,柴油机的比油耗也随之增大,柴油机效率随之下降。所以这样一个系统消耗了大量的燃料,降低了微电网的效率。因此,采用可调速发电系统代替固定速度发电机组。在此基础上,建立了调速发电系统的拓扑结构。本文提出了柴油机变速运行的原理,即根据功率的需要调节转速,控制负载转矩遵循比油耗低的区域,从而比定速节省大量的燃油。给出了基于制动比油耗图的发电机组定速和调速油耗计算实例。计算证实,可调速发电系统的应用结果显著节省燃料。

The work presents the feasibility study of an assembly-kit of a standalone DC solar refrigerator powered by PV energy, suitable for food conservation in rural villages with a specific focus on tropical-equatorial belt of Africa. The PV+refrigeration unit+controller is thought as a highly reliable, efficient, maintenance-free and durable package to be provided to the local users; the thermally-insulated envelope equipped with an energy storage system, instead, is designed to be constructed on-site, using local materials, and assembled with the package provided, according to guidelines resulting from the research activities. The preliminary assessment presented in the work allowed to identify the best components and solutions considering the analyzed application context. In particular, through the defined energy model and the carried out simulation it was possible to identify the optimal size of the refrigerated volume, of the energy storage and of the PV section.

The paper deals with line-disconnected operations of light railways vehicles using energy storage systems. In particular the suitability of on-board supercapacitors is investigated with reference to trams running along urban paths in catenary-free mode. Several tests on a real urban vehicle are presented in order to enable the evaluation of the losses in the different sections of the on-board power conversion system. These experimental data are used to estimate with good approximation the energy required for autonomous operations. A methodology called design to range is presented for properly sizing the super-capacitors bank needed to overcome different assigned distances with different road slopes.
