Battery 2nd life storage systems are a result of the synergies between the automotive and power generation sectors. They leverage the sustainability potential of electric vehicles (EVs) and renewable energy grid integration simultaneously. The vast experience of automobile manufacturers in battery system manufacturing and long-term operation in EVs provide a strong basis for replicating their success in the stationary storage market within smart grid applications. This paper provides the methodical and analytical basis for assessing an operational battery 2nd life system and deducting an effective control strategy for attaining maximum system performance with minimum battery cell aging. Suggested optimisation measures are based on a detailed analysis of logged data from Europe's first battery 2nd life system, focussing on SoCs, c-rates and cell temperatures.

The photovoltaic technology has proven to be an efficient way to convert solar energy into electricity, being able to extensively cover buildings energy needs, especially in Mediterranean climate such as the Italian one. However, the PV industry must overcome the difficulties generated by the end of the feed-in tariffs and the economic crisis. It is essential, therefore, to develop solutions, characterized by high levels of operative efficiency and effectiveness with particular reference to the building context. The proposed research is aimed to assess, under energy and economic points of view, a PVT-Solar Assisted Heat Pump (PVT-SAHP) system for space heating, cooling and domestic hot water production. In particular, the technical configuration allows to maximize the electrical performance of the PVT collectors and, at the same time, the seasonal COP of a small-size heat pump system, while reducing the electricity exchanged with the grid, and ensuring a high level of architectural integration.

In this paper, a measurement-based modeling technique for PV panels oriented to power electronics design is proposed. The proposed modelling approach aims at an accurate modeling of the whole PV curve and not only around a few remarkable points. The proposed approach is based on an experimental characterization of the module under test. In fact, the incompleteness of manufacturers' data and the knowledge of physical parameters are the main source of inaccuracy in existing modelling approaches. The proposed approach is applied to a four lumped parameters model of a Conergy E215P solar module. Tests are performed under natural light. The parameter identification procedure is described in detail. Simulation and experimental results are compared to test the accuracy of the proposed model. As it will be shown by the comparison between simulation and experimental results, the worst-case model current error within the current source region is equal to 1.19% and the worst-case voltage error is equal to 2.9% within the voltage source region.

This paper proposes an active switched quasi-Z-source inverter (AS-qZSI) topology, which is based on the classical qZSI. The proposed AS-qZSI only adds one switching device and diode to the classical qZSI, in order to increase the voltage boost ability. In comparison to classical qZSI under the same operating conditions, the proposed AS-qZSI provides higher boost ability and achieves lower voltage stress across the switching devices of the main inverter. The performance of the proposed AS-qZSI topology is verified with both the simulation results and the experimental results obtained from a laboratory prototype based on 32-bit DSP.

In the last years a growing interest towards DC Smart Grids has been registered due to high penetration of distributed generation systems with embedded storage. Trying to foresee the possible future scenarios of the power systems, it can be noticed that DC Smart Grids can be even preferable to AC Smart Grids in terms of flexibility and redundancy since they are compatible with the achievement of a DC Multibus working at different voltage levels. In this paper the Single-Star Bridge Cells Modular Multilevel Cascade Converter is used to create a DC Multibus. The performances of the system are analyzed considering different load configurations and coexistence of different voltage levels of the buses forming the DC Multibus. Results confirms the validity of the proposed solution and the robustness of the control system in case of load variations.

Automotive sector is one of the main sectors in terms of fuel consumption and environmental damage (pollutant air emissions). A great number of studies has been conducted in recent years on the convenience of a migration from fossil fuel vehicles to electric vehicles, with different approaches and assumptions and, generally, different conclusions. It is difficult, therefore, to make full use of these conclusions, especially for non-expert policy community. This paper proposes a simple but complete methodology to evaluate unitary operating cost of electric and conventional drive vehicles (ICE - internal combustion engine vehicle) in order to provide a repeatable comparison referring to main scenarios representative of realistic contexts. In detail, the comparison is based on a optimization mathematical procedure, which includes economic and environmental indicators, to evaluate operating cost of the vehicles.

The recent laboratory tests are showing progresses in both materials and production technology of Photo-Voltaic (PV) modules, nevertheless their efficiency yet results relatively low. Moreover, efficiency is also a very critical issue for already installed PV modules, because they were produced employing a less performing technology. In this scenario, a diagnostic approach able to check the current state of health of each single PV cell assumes a strategic importance. This paper introduces a thermography-based diagnostics able to provide a detailed, clear and unambiguous information, thanks to a computer aided investigation based on the InfraRed (IR) analysis: the proposed method, in fact, provides a fine diagnostics (both in numerical and in qualitative form) for each cell of the PV module. In addition, the paper proposes a software platform that implements the workflow and automatically generates a report, so resulting a fast and effective tool for the professionals of the Operation and Management (O&M).

The progress that distinguishes the contemporary age has allowed humanity to live in a world more and more comfortable, all this at the disadvantage of the exploitation of non-renewable energy and the health of the planet Earth. In construction industry, therefore, it is possible to observe an improvement in the matter of reducing energy consumption and the emissions of pollution. This is made possible with the concept of Smart House. In this regard, the aim of this work is to analyze a traditional building where it is required a property renovation of the electrical system. In this case, it is shown the effectiveness to choose of a home automation system both the point of view of the comfort offered and of the economical aspect. Finally, it is proposed the energy efficiency of the building made through the replacement of electrical appliances at energy-saving.

This paper proposes a sensorless control strategy for doubly-fed induction generators (DFIGs) in variable-speed wind turbine systems (WTS). The proposed scheme uses an extended Kalman filter (EKF) for estimation of rotor speed and rotor position. Moreover, the EKF is used to estimate the mechanical torque of the generator to allow for maximum power point tracking control for wind speeds below the nominal wind speed. For EKF design, the nonlinear state space model of the DFIG is derived. The estimation and control performance of the proposed sensorless control method are illustrated by simulation results at low, high, and close to the synchronous speed. The designed EKF is robust to machine parameter variations within reasonable limits. Finally, the performances of the EKF and a model reference adaptive system (MRAS) observer are compared for time-varying wind speeds.
