Wind-light-gas-seawater pumped storage isolated power system capacity optimal configuration method based on multi-objective optimization

Abstract

The invention discloses a wind-light-gas-seawater pumped storage isolated power system capacity optimal configuration method based on multi-objective optimization. The wind-light-gas-seawater pumped storage isolated power system capacity optimal configuration method comprises the steps of: 1) setting a control strategy of an isolated power system; 2) inputting day-ahead prediction data and basic parameters; 3) carrying out data processing by combining the input data with decision variables according to wind driven generators, photovoltaic modules, micro gas turbines and seawater pumped storage models; 4) and carrying out capacity optimal configuration on the wind-light-gas-seawater pumped storage isolated power system by combining with the step 3. The wind-light-gas-seawater pumped storage isolated power system capacity optimal configuration method can be used for carrying out capacity optimal configuration on the isolated power system composed of wind power generation, photovoltaic power generation, gas turbine power generation and seawater pumped storage.

Description

technical field [0001] The invention relates to a capacity optimization configuration method of a wind-solar-gas-seawater pumped storage isolated power system, which belongs to the technical field of optimal dispatching of new energy power systems. [0002] technical background [0003] Because many islands are far away from the mainland, they cannot be connected to the mainland power grid. At present, they can only rely on diesel generators and gas turbines on the island to meet the electricity demand. low reliability issues. [0004] Because many islands have abundant wind energy, solar energy resources, seawater resources and undulating terrain, it is possible to develop isolated power systems based on wind and solar complementary seawater pumped storage. Among them, using the sea as a natural reservoir can effectively reduce project investment costs and shorten the project construction period. The seawater pumped storage isolated power system based on wind-solar hybridi...
