Wind energy is one of the most significant contributors in distributed renewable energy resources and is expected to further grow in the next years, imposing new challenges especially regarding large future wind turbines with 10MW and more in terms of applied materials, structural loads as well as simulation and forecasting of wind conditions at specific sites. To overcome these challenges, precise wind farm models are required to ensure optimal power generation and fatigue load estimation. This paper deals with requirements for a real-time three-dimensional wind flow model which covers important aspects of wind flow in wind farms, on-site conditions and aerodynamic interactions of wind turbines. A simulation framework is proposed and described in detail. Simulation results are presented and show the prospect of future investigation opportunities.

The IGBT active clamp gate driver is a conveniently method used to protect the switch from the overvoltage by driving the gate input of the IGBT itself. The overvoltage is common during the turn-off of inductive loads or circuits with parasitic elements. This clamping circuit is generally embed into the gate driver circuits. The aim of this paper is to study and model the active clamp circuit giving a compact mathematical model for the power losses calculation. The losses calculation are needed for the heatsink sizing when the system is used in not conventional use, with single or repetitive overvoltages, as for example for the solid state circuit breakers (SSCB) without external passive clamp circuits. Moreover the study has been validated with experimental tests.

The global energy challenges impose important changes in electric energy production and transportation sectors, especially for developed countries. Today, the European road good transport sector and private mobility sector are crowded by different engine technologies which are evolving as real alternatives to internal combustion engine vehicles: in future years, an increase of electric vehicle penetration is expected. In this work, the effect of an electric vehicle fleet is simulated on a medium voltage grid, to analyze which are the effects of road transport sector electrification. A solution able to combine the batteries of electric vehicles and photovoltaic generators is proposed. Results of simulations on vehicle to grid application for peak shaving and considering profit criteria based on Day Ahead Market are discussed.

The digital models of windfarms provide a useful tool when monitoring and controlling wind generators digitally and remotely, allowing its maintenance and optimization, thus reducing the costs due to downtime and increasing the reliability of the elements that intervene in the conversion of wind energy to electric power. These aspects acquire even greater relevance when it comes to remote locations such as offshore wind farms. In this sense, this paper describes a MV cable model aimed at emulating its behavior and lifetime in order to carry out a preventive maintenance. The model is based on a combination of a dynamic MV cable model and a PCHIP-based interpolation algorithm, which have been developed in open source software OpenModelica.

This paper aims at investigating the CO2 emission, the fuel consumption, the energy contribution and the time connection of each generator in standards routes of a Platform Supply Vessel (PSV) using direct-current (DC) distribution system. Since the majority of the PSVs work with AC distribution grids, in this paper we trace a comparison between both distribution systems. The PSV has four 1850kW diesel generators, two 450kW auxiliary diesel generators and two batteries. The diesel generators operate at variable speed through an AC-DC converter and the batteries are connected to the DC grid through a DC-DC converter. The propulsion system is connected to the AC grid through an AC-DC-AC converter and is composed by two bow thrusters and two azimuth thrusters, The base loads and the service loads represents the other loads that a ship can have such as GPS, radars, hospitality and lighting. The results of this paper are obtained with HOMER energy. Moreover, the benefits obtained of operating the PSV’s with DC distribution system are enumerated.

This paper provides field generated data for single-axis-tracker (SAT) photo voltaic (PV) modules subjected to the semi-arid Northern Cape environment of South Africa. The research objectives are the investigation of the effects of dust soiling on PV module performance and the application of experimental dust mitigation methods. This includes the use of a hydrophobic anti-soiling coating and also the execution of a self-cleaning manoeuvre by the SAT systems. Two SAT systems were deployed to serve as experimental platform, from which data was obtained for a three month period (97 days). Raw data validation is established with comprehensive weather monitoring (ambient temperature, wind speed, wind direction, rainfall, pressure, and humidity), irradiance and PV module back sheet temperatures recorded, in accordance with the IEC61724 standard. An intelligent device was used to extract Current-Voltage (I-V) curves from individual PV modules. Maximum PV module power output is derived from the measured I-V curves, validated with a single-diode curve fitting routine. The comparative study between the different PV modules is done with a performance ratio (PR), defined as the temperature and irradiance corrected performance factor of a PV module. Contrary to the initial hypothesis, results indicated that the hydrophobic coating actually promoted dust soiling. The applied self-cleaning capability of the SAT system did not yield any conclusive results as a dust mitigation method. Finally, interesting in-field observations are discussed.

The increasing share of decentralized power generation, which is predominantly based on renewable energies, leads to higher requirements in power system operation. This means that new concepts with regard to the stability of power supply systems are unavoidable. In particular, the distribution networks in which most decentralized generators are connected must be actively controlled. They must, therefore, be equipped with new components, e.g. measurement systems and automatable actuators, in order to establish dynamic grid control functions. In addition, new concepts are needed to organize the control of the power supply system decentrally. A number of smart grid concepts have been developed and introduced. One concept is the Clustering Power System Approach (CPSA), which has been presented in previous papers.This paper focuses on dynamic smart grid operation in relation to the load-frequency control applied within the CPSA. Therefore, a hardware demonstrator is used to demonstrate the operation of the CPSA in a realistic test scenario. A number of power electronic prosumer emulators in combination with a smart grid regulator operate as interconnected power systems by representing individual load-frequency control areas in terms of technical control schemes. The results show that dynamic load-frequency control can be established at the distribution level.

Multiphase permanent magnet synchronous machines are receiving more and more interest in safety critical modern industry applications and in wind turbines, owing to their higher reliability, with respect to the classical three phase machines. In this context, diagnosing the stator windings status is necessary to guaranty the required high machine performance.In the present paper, the detection of stator inter-turn short-circuit, for six-phase AC permanent magnet machine, is investigated. The main contribution of the presented investigation is the assessment of stator inter-turn short-circuit detectability based on spectral analysis derived from the space vectors of the back-emfs accessible in the different $alpha-beta$ planes. The presented results are validated by means of two-dimensional finite element analysis, and then by experimental results, showing a very good agreement.

This paper introduces design, implementation and stable operation of a microgrid containing multiple distributed generation sources of wind, solar Photovoltaics (PV), and hydrogen fuel cells under multiple contingencies and disaster storms. This paper reports normal operating and contingency cases of the DG system variables that are synchronized with an AC grid in a smart grid environment. Both the data acquisition and control interface (DACI) and the low voltage data acquisition and control (LVDAC) modules which are specific to this microgrid provide monitoring and recording of multiple variables such as voltage, current, power, and frequency values. The operation of this smart grid scheme indicates that a large-scale DC power storage from multiple DG sources is feasible once reliable battery banks are available. This paper also reports harmonics and power quality issues caused by non-linear loads and a large-size DC to AC inverter connecting the DG modules to the AC grid. The results of the study are very promising in terms of increasing student interest and enthusiasm in modern electrical power systems of distributed generation micro grids that are integrated to a smart grid through a state-of-the art data acquisition and instrumentation devices.
