This paper aims to develop a condition monitoring architecture for induction machines, with focus on bearing faults. The main objective of this paper is to identify fault signatures at an early stage by using high-resolution frequency estimation techniques. In particular, we present two subspace methods, which are Root-MUSIC and ESPRIT. Once the frequencies are determined, the amplitude estimation is obtained by using the Least Squares Estimator (LSE). Finally, the amplitude estimation is used to derive a fault severity criterion. The experimental results show that the proposed architecture has the ability to measure the faults severity.

This paper introduces the real-time flash flood detection method for stationary surveillance cameras. It can be applied for rural and urban areas and capable of working during day time. The background subtraction was used to detect all changes appear in a scene. After this step, many pixel belonging to the same moving objects may be divided. They are united by morphological closing. Too small separate objects are then removed form the scene. Color probability was calculated for all the pixels belonging to a foreground mask and connected components with low probability value were filtered out. Finally, results were improved by edge density and boundary roughness. The most time consuming step was implemented in parallel using CUDA. Real-time performance was achieved in this way. The algorithm was tested on publicly accepted video.

As the number of Electric Vehicles (EVs) has continuously increased in the last years, due to environmental issues, the interest is to find the maximal penetration rate of EVs, which can meet both, technical and environmental constraints. The technical impacts can be reduced by applying an Energy Management Strategy (EMS), which in the present study increases the maximal allowed EVs' penetration rate with over 41%. The energetic mix has a great importance concerning the environmental impacts. If the renewable energy is injected in the grid as distributed energy, it also has benefic impacts regarding the technical constraints. Consequently, a multi-objective and multi-variable optimization is performed, in order to find an optimal energetic mix for a maximal number of EVs, with an appropriate EMS.

In this paper, an application of evolutionary game dynamics is proposed in order to profit from the desirable features of mixed strategist dynamics in the solution of distributed resource allocation problems. The key idea of this approach is to define mixed strategies that represent the vertices of the convex hull of the set of feasible solutions defined by the constraints of the local optimization problems. With this approach, the dynamics of the state vector is restricted to a subset of the simplex. Details of the defintion of appropriate mixed strategies, payoff functions, and the multi-population modeling followed for this problem are provided.

This paper deals with the integration of the electric power-conditioning interface to the Fuel Cell (FC) module for embedded electric power generation. Specifically, the current study aims to propose an adequate control strategy to achieve a high efficiency of a compact 20kW DC/DC PEMFC output multiphase converter based on new wide-bandgap technology devices. The proposed control strategy is based on the part-load approach fulfilling demanding specifications such as low input current ripple, high performances of the converter over the load power range and small losses enabling the simplification of the cooling circuit.

Rapid development of Distributed Energy Resources (DERs) and DC-powered loads entails the possibility of DC micro-grids to revenge conventional AC distribution networks. In addition, a continuous evolution of the power electronic technology allowing the highest possible power of DER production also makes the DC micro-grids more feasible in the near future. Although energy efficiency and steady state characteristics of the DC micro-grids becomes more mature, transient behaviors of DC microgrids under different control aspects and loads are under-investigated. In order to analyze and validate the dynamic behaviors of DC microgrids, a scalable-configurable laboratory DC microgrid test-bench is implemented and presented in this paper.

This paper presents a model predictive current control applied to a proposed single-phase five-level active rectifier (FLAR). This current control strategy uses the discrete-time nature of the active rectifier to define its state in each sampling interval. Although the switching frequency is not constant, this current control strategy allows to follow the reference with low total harmonic distortion (THDF). The implementation of the active rectifier that was used to obtain the experimental results is described in detail along the paper, presenting the circuit topology, the principle of operation, the power theory, and the current control strategy. The experimental results confirm the robustness and good performance (with low current THDF and controlled output voltage) of the proposed single-phase FLAR operating with model predictive current control.

Fast isolation and detection of DC faults is currently a limiting factor in high power DC transmission grid development. Recent research has shown that the role of DC/DC converters is becoming increasingly important in solving various DC grid challenges such as voltage stepping, galvanic isolation and power regulation. This paper focuses on an additional important feature of bidirectional dual active bridge (DAB) DC-DC converters which make it attractive for future DC grids; it's inherent fault isolation capability which does not need control intervention to limit fault current in case of the most severe DC faults. Detailed analytical, simulation and experimental study are performed by subjecting the converter to DC short circuit faults at its DC voltage terminals. The results obtained have shown significant advantage of DAB where fault current is less than rated current during the fault duration. Thus no control action is necessary from the non-faulted bridge to limit fault current and no external DC circuit breakers are required. This advantage makes DAB converter feasible for DC grid integration.

In this paper, a new multi-purpose switched reluctance machine drive with charging capabilities is introduced. This topology satisfies propulsion requirements and allows single phase as well as three-phase AC charging. In charging mode, the machine windings are used as inductors and the zero torque condition is maintained by canceling out all tangential forces. Every component of the SRM drive is used during charging and no additional components are needed. The proposed topology is theoretically analyzed, and its validity is verified by simulation software.
