This paper deals with dynamic simulation of a directly driven Permanent Magnet Synchronous Generator (PMSG) with a full scale converter interfaced to the grid. A comparative assessment of two control strategies is the main focus of this paper. The first is the SVM based voltage oriented control strategy and the second is the hysteresis current control strategy. Maximum power point tracking and pitch angle control is also modeled. The controller performance is analyzed through simulation results with various changes in wind velocity.Index Terms-PMSG, pitch control, maximum power point tracking, voltage oriented control, hysteresis current control.

“…Aerodynamic braking uses pitch angle mechanism and it is used for pitch controlled wind turbines or active stall controlled turbines and is expensive for small wind turbines like the ones considered under this study. Mechanical braking is the most common method used for the small wind turbines [12,13] and this mechanism is used to stop the 5.5 kW wind turbine used in the CIGRE network in the case of the loss of the grid supply in this paper.…”

High quality electricity services are the prime objectives in the modern power systems around the world. One of the main players to achieve this is the protection of the system which needs to be fast, reliable and cost effective. The study about the protection of the Low Voltage (LV) CIGRE distribution grid and networks like this has been proposed in this paper. The main objective of this paper is to develop protection against short circuit faults which might appear anywhere in the network. The protection of the power networks that comprises of renewable energy generation units is complicated because of the bidirectional flow of the current and is a challenge for the protection engineers. The selection of the protection devices in this paper is made to protect the network against faults in grid connected and island mode of operation. Ultra-fast fuses are proposed in order to protect the inverters used for Photovoltaic (PV) and battery applications. The disconnection of the PV solar panels when in island mode is made by proposing switch disconnecting devices. ABB is currently using these kinds of disconnection devices for the purpose of protecting solar panels against over voltages in the case of islanding. The over speed protection of the existing Wind Turbine Generator (WTG) in the CIGRE network in case of grid loss is also proposed in this paper.

Small wind turbines are commonly single-turbine installations owned by individual homeowners or farmers for on-site electricity consumption, and are becoming an attractive alternative for off-grid electrification and water pumping, both as stand-alone applications and in combination with other energy technologies such as photovoltaic, small hydro or diesel engines. The cost of energy alone is not the only criterion to consider, other aspects like system performance, suitability for a given wind regime, reliability under normal and extreme wind conditions, efficiency in energy storage and exploitation, and overall system life are often equally important. This research deals with the development of small-scale wind energy systems for increasing the productivity of wind power and achieving the better exploitation of generated energy. The proposed wind turbine controller is based on the variable-speed variable-pitch power regulation strategy, using the combination of chattering torque control and PI pitch control. The hardware-in-the-loop (HIL) simulation and on-site experimental testing in rural area are presented. Compressed air energy storage (CAES) strategy for the energy exploitation is also discussed.
