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.

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.

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.

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.

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.
