Description

technical field [0001] The invention belongs to the field of electrical automation, and in particular relates to a capacity optimization configuration method of an energy storage system based on source-load-storage coordinated control. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's production and life, bringing endless convenience to people's production and life. Therefore, ensuring a stable and reliable supply of electric energy has become one of the most important tasks of the power system. [0003] At the same time, with the increasingly serious environmental problems, new energy power generation systems have gradually begun to be incorporated into the grid. With the integration of new energy power generation systems into the power grid, the randomness, volatility and intermittent characteristics of new energy pow...

Problems solved by technology

[0005] If the capacity of the energy storage system is too large, it will easily lead to high cost, and the greater the capacity of the energy storage system, the lower its reliability and safety, which will easily become a hidden danger to the safe operation of the power grid

However, if the capacity configuration of the energy storage system is too small, the role of the energy storage system may not be able to play its role, and it may also cause the abandonment of wind and water in the new energy system.

However, there is no good calculation or optimization method for the capacity allocation of energy storage systems; existing configurations are generally based on experience, which not only lacks actual theoretical research, but also has poor objectivity and scientificity; and the application effect is also poor. not good
