In recent years, Microinverters have gained much attention since the direct connection of PV modules to the grid can increase the amount of harvested energy when compared to traditional string inverters. In addition, the use of microinverters results in a modular system which can grow over time, with increased reliability. Key aspects for the implementation of a microinverter are that the selected power converter topology is required to have high voltage gain to interface the low voltage PV input to the grid, and to have high efficiency. Usually, microinverters are implemented in a two-stage approach which impacts overall power conversion efficiency. Further, a fly-back converter is commonly used as input stage, which has several disadvantages such as high EM noise, high semiconductor voltage stress, and that a highly discontinuous current is drawn from the PV module. To cope with these issues, a single stage microinverter topology based on a push-pull converter integrated with a quasi-Z source network and coupled with a voltage unfolder is presented in this paper. The proposed topology results in reduced component count, low voltage stress and reduced EM noise.

Photovoltaic modules parametric identification is often performed based on data available in the data sheet and referred to standard test conditions. On-line identification is trickier when irradiance and temperature sensors are not available. In this paper, an identification procedure is presented aiming to identify some module fault conditions that often occur during its lifetime. The proposed approach is applied to a large database of current vs voltage curves that are experimentally measured on a real photovoltaic plant.

A newly conceived symmetrical three-phase E- Type (3 $Phi$7L E-Type) Inverter is proposed and analyzed in this paper. Converter topology is based on the single leg T- Type Inverter. The proposed topology shows seven voltage levels at the output providing better performance in terms of current and voltage stress of the power semiconductors and efficiency. The theoretical investigation has been carried out with reference to photovoltaic (PV) applications. A suitable thermal model of the power semiconductors has been developed in Plexim/PLECS environment. Simulation results of the 3 $Phi$7L E-Type Inverter are performed in Matlab/Simulink environment. Furthermore, the prototype of the proposed converter has been carefully tested in order to validate the theoretical analysis.

This paper presents a technique to relate the temperature distribution over solar panel, achievable by means of the UAV thermography, with the electrical power distribution which is the cause of those temperatures. Differently from a mere thermal analysis, that can only identify “hotter” regions throughout the solar field, this technique allows evaluating electrical power losses associated to malfunctioning events. The method is based on the energy balance between the sun irradiance, which tends to heat up the solar cells, and the electrical behavior, which tends to cool down if the cell is converting light, while tends to further increase the cell temperature in those cases in which the cell behaves as a load. The reliability of the technique is evidenced by providing simulated thermal maps, achieved by means of known electrical and irradiance conditions, which are analyzed to re-achieve the starting electrical condition at the single cell level.

Silicon Carbide (SiC) MOSFETs, as wide-bandgap semiconductor device, are becoming increasingly popular. They can switch at much higher frequency when compared to their silicon (Si) counterparts and can viably supply high-speed electrical drives. High-speed machines are profitably used in aeronautical or electric vehicle applications, offering drastic reduction of encumbrance and weight. On the other hand, industrial motor drives usually include a long-shielded cable to connect the inverter to the induction motor. This, together with high frequency operation of the SiC devices, emphasizes the effect of parasitics such as stray inductances and capacitances, which generates reflected wave transient overvoltage on motor terminals. In this paper, switching performance of SiC MOSFETs is systematically studied and compared to the performance of Si devices for low-voltage induction motor loads. For the Si-based inverter configuration the Neutral Point Clamped (NPC) 3-level inverter has been chosen, being it highly utilized in industrial applications. The two systems are compared in terms of switching performance, overvoltages, and power losses for the same output voltage capabilities. Simulations are carried out by realistic models of power switch modules. The goal was to analyze potential solutions for switching performance improvement and mitigation of reflected waves, as well as for future analysis of the electric aging phenomena.

This paper presents a new approach for supercapacitors (SCs) characterization using temporal method taking into account the influence of the dynamics constraints, such as number of cycles and rms value of DC-current ripple. This characterization is done using supercapacitor cycler BT2000 test bench. From experimental data, the parameters of the supercapacitor (SC) (series resistance and capacitance) are calculated from the voltage response compared to current input. The contribution of this paper is focused on the parameters dependence study according to the dynamics constraints listed previously (number of cycles and rms value of DC-current ripple). Finally, the experimental results, which show a dependence of series resistance (ESR) and capacitance (C) compared to these constraints, are presented.

Bypass diode failures have been observed within solar photovoltaic (PV) plants after thunderstorm activity, with no evidence of direct lightning strikes to the PV plant. Previous research has found that bypass diodes are typically weakest in reverse bias, when the reverse current reaches a critical threshold. This paper suggests the use of metal oxide varistors (MOVs) as a potential bypass diode protection measure. MOVs are shown to adequately protect a bypass diode to a level more than double that of where a bypass diode would normally fail, by providing an alternative conduction path for surges induced within a PV installation.

Electric vehicles range is limited by the available storage systems and it is influenced by many external factors such as ambient temperature, vehicle auxiliary systems and driving patterns. An accurate and reliable estimation of the remaining energy and, as a consequence, of the available travelling distance is one of the key factors that allows drivers to consciously take advantage of their electric vehicle (EV).The present paper describes the application of a previously-defined model for EVs batteries to estimate on line the available range. The effectiveness of the proposed methodology, which has been designed in order to use a reduced set of measurements, has been validated on a real Lithium-ion cell simulating three different EVs under two different temperatures and with two standard test driving cycles.

This paper addresses the impact of high penetration of renewable energy sources (RES), in particular wind and solar power generation on the western transmission network of the South African (Eskom) power system. The study focuses on the power system’s stability, specifically the frequency dynamics. With a decline in power system inertia, inertial response emulated by inverter based RES, is considered as a means to restore the system’s inertia. Virtual inertia is seen as a valuable ”resource”, but comes at the cost of active power generation. In addition virtual inertia also provides an additional degree of control, which must be used in an optimal manner to provide maximum system stability at a reasonable cost to power generation. This paper utilizes an optimal virtual inertia placement and allocation method, for the western transmission network considering a trip of the Koeberg nuclear power plant in the Western Cape province. Simulation test results show that the virtual inertia and optimal allocation improves the system stability significantly. This in return gives additional incentive for RES integration.

In this paper a deep investigation of supercapacitor device modeling is performed with specific reference to hybrid energy storage modules, suitable to support both all electric /hybrid propulsion and on board MVDC distribution marine systems. In those applications, the combination of batteries and supercapacitors in realizing energy storage hybrid devices overtakes the intrinsic disadvantages of single use of electrochemical batteries and supercapacitors. On the other hand, proper design and management strategies of hybrid architecture are required in order to achieve the best performance in terms of dynamic and life cycle assessment on load profile of marine applications. In this way, the main results presented in this paper consists in a simple quadratic mathematical model of supercapacitor, evaluated as a quadratic function of the ultra-capacitor voltage, which is validated experimentally on the base of operative-cycle-based loading profiles, representative of marine application.The results and comparison reported in this work confirm the validity of the proposed model for preliminary design of hybrid energy storage systems and management strategies evaluation on the electrification of ship power systems.
