The invention relates to an energy storage power station dynamic configuration method, system and device considering uncertainty, and the method comprises the steps: S100, building a wind power output model based on a fuzzy opportunity constraint programming method, and building a photovoltaic output model based on an uncertainty set; s200, determining a locating and sizing strategy of the energy storage power station by adopting a PV curve; s300, considering the randomness of the user demand response, and establishing a price-based user demand response uncertainty model; and S400, establishing an energy storage dynamic planning model based on the constructed wind power output model, the photovoltaic output model, the user demand response uncertainty model, the addressing and sizing strategy and the corresponding relationship between the power grid energy storage mode and the user demand response, and solving the energy storage power station configuration mode based on the energy storage dynamic planning model. According to different seasons, time periods and power grid operation scene replacement conditions, the energy storage configuration mode is dynamically updated, energy storage devices are increased and decreased in time, flexible distribution and dynamic layout of energy storage are achieved, and the stability of the system is improved.

Description

technical field [0001] The invention relates to the technical field of energy storage configuration, in particular to a dynamic configuration method, system and equipment for an energy storage power station considering uncertainty. Background technique [0002] At present, my country's energy and environmental crisis is becoming more and more serious, and the contradiction between the significant increase in energy demand and the depletion of primary energy continues to deepen. As the energy systems of countries around the world are gradually transforming to clean and renewable, the proportion of clean electricity in social energy consumption continues to increase, and new power systems based on clean energy such as wind power and photovoltaics will gradually replace traditional fossil energy. Power generation-based high-carbon emission power system. [0003] The output of new energy has the characteristics of randomness, volatility, intermittency, and weak regulation abili...

AI Technical Summary

Problems solved by technology

[0005] Most of the traditional energy storage configuration methods use centralized energy storage, which is relatively simple and does not consider the flexible effect of user-side response. The flexibility is not high, and the effect of new energy consumption is not obvious enough.
