“…The kinetic energy stored in their inertia gives the turbine the possibility to support primary frequency control for a short period. One particular advantage of variable-speed wind turbines is that unlike thermal or gas turbine power plants, they can increase their output power almost instantaneously [17]. This is an important feature, especially for a microgrid system when it goes to islanding-mode operation.…”

This paper describes a control approach applied on a doubly fed induction generator (DFIG) to provide both voltage and frequency regulation capabilities, and hence, an improvement in the dynamic behavior of a microgrid system. The microgrid system is assumed to be a portion of a medium voltage distribution feeder and is supplied by two distributed generation (DG) units, i.e., a gasturbine synchronous generator and a variable-speed wind turbine with DFIG. A control approach algorithm is proposed for the DFIG unit to improve both voltage and primary frequency controls. Two distinct operation modes, i.e., grid-connected and islanding mode, are used in the proposed approach for proper transfer from normal to islanding operation. Case studies are simulated based on both planned and unplanned islanding scenarios to evaluate the performance of the control approach. The study results show that the proposed control approach for DGs in the microgrid increase the microgrid system's dynamic performance, reduce frequency changes, and improve bus voltages regulation during islanding and autonomous operations.Index Terms-Distributed generation (DG), doubly fed induction generator (DFIG), frequency and voltage controls, islanding, microgrid.

“…According to (11)the electromechanical torque is directly dependent to i and the following procedure can be used forSpeed controller. Controller measures the actual speed of rotor, the mechanical power and then mechanical torque are derived from this value and (5), then the value of i needed to realize the desired electromechanical torque is calculated using (11).The resulting i is fed to DFIG [8].…”

power system with high penetration of wind power requires a developed control strategy to obtain optimal dynamic performance under load variations. An algorithm utilizing internal model control (IMC) design method for the control of doubly fed induction generator (DFIG) operating at variable speed constant frequency is proposed. The proposed structure is a stand-alone generating system and feeds a factory. Two distinct cases are simulated to illustrate the abilities of DFIG on frequency regulation considering the proposed controller. All simulations developed in PSCAD/EMTC software.

“…This would mean that no wind passes through the blades of the turbine. However, this is not the case as the Betz Limit defines the maximum level of energy extractable from the wind [13]. The Betz Limit states that at any instant the maximum percentage of energy extractable from the wind is 59 %.…”
