摘要：

Energy management of isolated micro-grid with wind turbines and seawater desalination devices is of great significance to the use of wind power, the supply of fresh water resources, and the economic operation of micro-grid. First, we constructed isolated micro-grid model including wind turbines, seawater desalination devices, diesel generator, battery and super capacitor. Then, on the basis of stable operation, considering battery life loss under different SOC states and different operation conditions and the controllability of seawater desalination, as well as the seawater desalination production profit, we constructed a micro-grid economic model and then proposed a long-term energy management strategy aiming at economic operation. Example analysis based on wind speed data indicates that the micro-grid which operates 24 hours under energy management strategy reaps the benefits 95.61 Yuan while the micro-grid without energy management strategy reaps the benefits 92.81 Yuan. Results verify the correctness, feasibility, and economy of the proposed strategy. It is concluded that the strategy can improve economic efficiency of micro-grid. ©, 2015, Science Press.
