Real-time integration of control strategies for an isolated DFIG-based WECS

Performance of a vector control for DFIG driven by wind turbine: real time simulation using DS1104 controller board

“…Fundamentally, the indirect field oriented method using the proportional integral correctors consists of two control loops [2]. The first loop serves to calculate reference rotor currents (Irq*, Ird*), this control loop gets its reference from the maximum power point tracking algorithm (MPPT) in order to optimize the power produced from the generator for each wind speed changes.…”

“…In recent years, the world has known a rapid evolution in various sectors that means the increase in demand on electrical energy; The uses of traditional fossil and nuclear energy resources pollute the environment, for this reasons countries are focused on development and exploitation of renewable energy sources such as biomasses, wind energy and solar energy which can offer the opportunity to produce the electrical energy in a clean way and help to save the environment [1]. Wind energy is one of the most effective and clean resource, it presents a promising and important source of energy with low cost, so many researchers have been focused on wind energy systems to develop new technologies in order to optimize the capture wind and the electrical power produced [2,4].…”

Optimal Design of Fractional Order Vector Controller Using Hardware-in-Loop (HIL) and Opal RT for Wind Energy System

“…But in some cases there may be chances of overrun due to the constraint of fixed time step Ts, when the time required to perform the calculation is more than the Ts and real time simulation may miss the synchronization. The HIL based real time simulation has been used effectively in various power system application such as DFIG control [25], grid integration [26], multilevel converter control [27], Fault analysis in IEEE-9 bus system [28], analysis of IEEE-5 bus system [29], and stator fault improvement in PMSM [30].…”
