PROJECT TITLE :
Modelling and robust control design of astandalone wind-based energy Storagegeneration unit powering an inductionmotorvariable-displacement pressure compensatedpump - 2016
This study investigates the application of the sliding mode controller (SMC) for induction motor drive variable-displacement pressure-compensated pump (VDPC) system powered by an isolated wind/storage unit. The variable-speed wind turbine (WT) is proposed to drive a permanent magnet synchronous generator (PMSG) that, feeds a storing energy unit and stand-alone dynamic load. Energy storage systems are needed for power balance quality in isolated wind power systems. Initially, the holistic model of the entire system is achieved, as well as the PMSG, the uncontrolled rectifier, the buck converter, the storage system, induction machine and therefore the VDPC pump. The power absorbed by the connected hundreds can be effectively delivered and supplied by the proposed WT and energy storage systems, subject to sliding mode management. The main functions are to provide 220 V/50 Hz through a 3-part inverter and adjust the IM speed and VDPC pump flow rate. The performance of the proposed system is compared with the neural network management and the standard PID management. The simulation results show that the proposed system with the SMC and neural network controllers has good performance and smart prediction of the electrical parameter waveforms compared with the case of the standard PID controller.
