Wind power sea water desalination integrated system and method for isolated grid

Abstract

The invention provides a wind power sea water desalination integrated system for an isolated grid. The wind power sea water desalination integrated system comprises a power system, a control integrated system and a sea water desalination system. The power system supplies power to sea water desalination devices by optimized dispatching of the control integrated system. The control integrated system is used for controlling the power system. The power system comprises wind turbine generators, at least one energy storage system and diesel generators. The control integrated system is used for controlling the power system. The sea water desalination system comprises the sea water desalination devices. The wind turbine generators, the energy storage systems, the generators and the sea water desalination devices are connected to the micro-grid in parallel. The system solves the problem that energy consumption of traditional sea water desalination industry is high, and the technical problems that an existing sea water desalination device adopting wind power energy needs to use a large number of storage batteries, electricity energy loss is high, maintenance is difficult and cost is high.

Description

technical field [0001] The invention belongs to the field of seawater desalination of wind power, and in particular relates to an integrated system and method for desalination of seawater of wind power with intelligent microgrid capable of independent operation. Background technique [0002] At present, the fans used for seawater desalination (including brackish water desalination) are generally off-grid wind turbines. Because the natural characteristics of wind energy are that the wind speed changes from time to time, the energy supply is unstable, intermittent and fluctuating, which contradicts the requirements of seawater desalination equipment for stable energy supply. Under normal circumstances, when the wind speed is high, the electric energy generated by the wind turbine is not only supplied to the load, but the excess electric energy is stored by the battery. The electric energy in the battery is output to the load through the electric energy conversion device; when...
