离网型风电反渗透海水淡化系统精细化设计

ELABORATE DESIGN FOR REVERSE OSMOSIS SEAWATER DESALINATION SYSTEM BASED ON STAND ALONE WIND POWER

为进一步降低海水淡化的成本,同时提高资源利用效率,提出一个精细的离网型风电海水淡化系统动态优化设计模型。该优化设计模型以风电、储能设备和海水淡化装置的物理模型为基础,通过求解数学规划问题,可得到系统各部分的最优容量配置和实时运行方式。该模型最大的特点是考虑了风能的波动性,在风能动态变化的前提下,得到的优化设计结果比静态的设计更具现实意义。

Reverse osmosis desalination driven by wind power is a new approach to solve fresh water shortage in coastal areas. In order to reduce the cost and achieve more efficient utilization of resources, an exquisite model for the optimal design of off-grid wind power desalination system was proposed, which was established based on the physical models of wind power, energy storage device and desalination unit. The optimal configuration of desalination system driven by wind power and its best operation regime could be obtained via mathematic optimization. Considering the fluctuation of wind power in the optimization process was the key feature of the model. Under premise of wind energy dynamic change, the optimization design is closer to the reality compared with a simple static one.
