This paper aims to address the design, modelling and optimization procedure of electrical generators for direct drive wind turbine application by introducing a new transverse flux permanent magnet machine (TFPM). The proposed TFPM benefits from characteristics such as: using ferrite PMs instead of rare-earth PMs, fully utilization of PMs, employing only one PM per phase, and cancelling all the even order harmonics. Design algorithm of the TFPM for direct drive wind turbine application is proposed which employs 3-D magnetic equivalent circuit method instead of time consuming finite element analysis (FEA). The MEC method is developed by taking account of rotor movement, iron saturation effect and fringing flux. The MEC results are compared with FEA in terms of accuracy and processing time. In order to improve the TFPM torque characteristics, the Taguchi optimization method is employed and the rated torque along with torque ripple are improved significantly.

The connection of wind farms to the grid and their dynamic behavior under different conditions is a real challenging issue which resulted in providing new instructions for the network. One of the important topics related to grid standards is Low-Voltage Ride-Through capability. In recent years, The application of Brushless Doubly Fed Induction Generator (BDFIG) in the wind farms has drawn the attention of researchers. This generator has more advantages than other common generators, including the Doubly Fed Induction Generator (DFIG). In this paper, the performance of the BDFIG under fault conditions in the grid is examined and monitored in order to improve LVRT while considering the dynamic model of the BDFIG connected to a wind turbine. In this method, the reactive power and speed are controlled for stable performance of the generator under various grid conditions. A converter is used to connect the stator control winding to the power grid, which DC link voltage is adjusted using multiple PI controllers under fault conditions. In addition, two controlling systems based on the conventional PI controllers are proposed to control the generator side converter and the wind turbines step angle. The results demonstrate good dynamic performance of the examined generator under different grid conditions achieved by the proposed controlling method without using any additional hardware such as a Crowbar.

High energy density, efficiency, and life cycle and rapid charge/discharge are merits of flywheel energy storage systems (FESSs) which make them noteworthy in various fields. This paper proposed a double-stator Flux Switching Permanent Magnet Machine (FSPM) for FESSs. Since there are no windings and Permanent magnets (PMs) on the rotor structure, high speed and low rotor loss operation are feasible, which are appropriate for FESSs in electrical vehicles. Also, the double air gap structure facilitates rotor thermal ventilation at vacuum. The PM and core material are chosen somewhat that the core losses and demagnetization will be minimized. Finally, two structures of FSPM are simulated and analyzed by Finite Element Analysis (FEA).

Magnetic switch is an inductor with the capability of saturation that uses the non-linear curve of magnetic materials. This saturable inductor performs switching operation using the concept of magnetic saturation as shifting from a very high impedance area to very low impedance area. Magnetic switch appropriate design for switch optimal performance is very important. The core material and structure parameters, coil material and structure, the cross-section of conductors, core cross-sectional area and the number of coil turns, affect on design trend. Despite the importance of magnetic switch design on its operation, no design procedure has been developed so far. In this paper, the structure and core dimensions on designing and operation of the magnetic switch are investigated and simulation results are provided. For different parts of the core, magnetic flux density distribution is shown and optimum size concerning the limitations suggested for the magnetic switch core.

Electricity demand prediction is an important task in smart power grid. The measured load values along time compose the load time series. The electrical load time series is a sequence that not only is crumple in many parts but also has self-similarity characteristic. So, a load sequence can be considered as a fractal. The fractal dimension shows how the fractal shape is complex and snuggle. Therefore, the fractal dimension is a good property of the load sequence that can be used beside the original load history for load forecasting. A short-term load forecasting method is proposed in this work that benefits the fractal features for characterizing the consumed electricity. The extracted features are fed into two different predictors: support vector regression and feed forward neural network. The experiments on two electricity datasets of Ireland and Canada show decreasing of the load prediction error using fractal features.

Dissemination of distributed energy resources (DERs) manifests the precious idea of green power generation. Aggregation of several DER units into the existing power network has become a principal challenge. To solve this, proper communication system for DER data exchange with the power utility need to be determined. DER interconnection with the power grid should be studied in two main levels of physical electricity connection and information transfer layer. The main objective of this paper is to study possible data exchange architectures for communication between a DER controller and a power utility operator. We extracted 9 different scenarios that fully cover DER interactions with other units. This paper provides a better understanding of a DER connection to power system components, defines the few related standards and design factors, extracts 9 communication scenarios based on reliable and qualified connections and discusses the optimized communication techniques for DER routes.

Vibration of wind turbine blades is a critical parameter to study its durability and performance. Active control using piezoelectric sensors and actuators have been emerged as a promising technology. In the present work, finite element analysis (FEA) has been developed for vibration analysis of a smart wind turbine blade, in which a piezoelectric layer is integrated on the blade layers. The numerical model of the blade with active and inactive piezoelectric actuator was constructed in COMSOL Multiphysics. Modal analysis has been performed to identify natural frequencies. It was shown that usage of piezoelectric layer increases the blade stiffness, thus increases the blade natural frequencies. These results indicate the feasibility of using piezoelectric actuators as a smart material for vibration suppression in the wind turbine blades.

Future smart grids will be interconnected with several multi-owner networks with multiple interests and goals. The security of this interconnected network is extremely difficult. Cyber-attacks have increased sharply in recent years. Increasing the scope of intelligent system increases the attention for cyber threats. By increasing the system's intelligence the range of cyber-attacks increases. With the advent of smart home and new concepts such as the Internet, attacker have made many devices much easier than their physical access. An attacker with access to system information through eavesdropping identifies the best possible attack time. In this paper a bi-level model proposed for the cyber-attacks and defense against it. The first part is a cyber-attack. In this section, the entire network includes the microgrids (MGs) and the part that belongs to the distribution company, with the same communication structure. For the attacker, the attack limit and the resource constraints for the attack are considered. The second part assumes that the network has different infrastructures. The distribution company uses fiber optic cables. Which is almost impenetrable and invaded. The other MGs use each of the different infrastructures. In the third case, the cyber-physical coordinate attack is done to the system. The real 94-bus network in Portugal has been used to investigate cyber-attacks in this paper.

In low-speed wind power systems, it is possible to remove the gearbox from the wind turbine structure by using permanent magnet synchronous generators and reduce the costs of construction, weight and maintenance. Therefore, in this paper, a single-phase grid connected impedance source inverter is studied for power management of low-speed synchronous magnet generators. Considering capability of the inverter to operate either in buck or boost modes, an extra DC-DC converter is not required in maximum power point tracking of the wind energy conversion systems. To cope with the non-minimum phase characteristic of the impedance source converter, an indirect controller is designed to regulate inverter input voltage as well as maximum power tracking of the wind turbine. Simulation results in the MATLAB/SIMULINK environment indicate efficiency of the proposed controller in maximum power point tracking of the grid connected renewable power plant.
