Operation and control of isolated microgrid with wind turbines and seawater desalination equipment

The coupled operation of large-scale off-grid wind power and energy-intensive seawater desalination equipments will lead future direction for wind power application and desalination industry. In this paper, based on load characteristics of desalination devices and operating characteristics of wind turbines, the control strategies of isolated microgrid with wind power, energy storage system and seawater desalination equipments are discussed firstly. To maintain stability of the system, a coordinated control strategy of isolated microgrid is proposed. A simulation is modeled on Matlab/Simulink to verify the correctness of the proposed coordinated control strategy. To go further, a real-time simulation platform is built based on PXI and PC. PXI is the place where digital model of the microgrid runs on and PC runs the monitoring system. Real-time simulation results also verify the feasibility of the proposed coordinated control strategy.
