Performance analysis for parallel operation of multimode droop controller doubly fed induction generator based wind energy conversion system with other wind unit, solar unit, loads, and FACTS device

Due to its numerous advantages, wind turbines with changeable speed power production systems are increasingly being used. This study proposes the architecture and specifications of an induction turbine generating wind system, as well as PI controller-based DC voltage link regulator and optimal torque control system. The suggested control technique as stated in this paper allows the system to function in grid linked mode as well as islanded mode and also in parallel with other power generation units, loads, FACTS devices, etc. This paper involves the analysis of different test cases in grid connected mode as well as islanded mode with PV generation unit, passive loads, induction motor loads, other wind energy generation systems. The paper also includes the analysis of response of the system with the switching on and off of the other units. MATLAB 2013a thereby validates the system findings and analysis.
