The oil-electricity hybrid energy storage power supply shelter is characterized by comprising an oil tank, a diesel generator connected with the oil tank, a unit controller used for controlling the output power of the diesel generator, a battery pack, an inverter connected with the output end of the battery pack, a battery controller used for controlling the output power of the battery pack, a power distribution cabinet used for being connected with external electric equipment and an energy storage square cabin controller, wherein the energy storage square cabin controller is in communication connection with the unit controller, the energy storage square cabin controller is in communication connection with the battery controller, the output end of the diesel generator is connected with the power distribution cabinet through an alternating current bus, and the output end of the inverter is connected with the power distribution cabinet through an alternating current bus.

Description

technical field [0001] The invention relates to the technical field of mobile energy storage power shelters, in particular to an oil-electric hybrid energy storage power shelter and a global optimal discharge control method. Background technique [0002] In recent years, due to its strong mobility and convenient deployment, mobile energy storage power supply shelters have been widely used in application scenarios such as emergency power supply guarantee, distribution network non-stop operation, temporary expansion of distribution network, and important load power supply protection. Most of the energy storage power shelters use diesel generators, but during the power distribution and power supply operation of diesel generators, due to the high price of oil, there are disadvantages such as high operating costs, high noise, and large pollution. In addition, there are also mobile energy storage power shelters based on battery packs, but the battery energy storage system has insu...

AI Technical Summary

Problems solved by technology

Most of the energy storage power supply cabins use diesel generators, but during the power distribution and power supply operation of diesel generators, due to the high price of oil, there are disadvantages such as high operating costs, high noise, and large pollution.

In addition, there are also mobile energy storage power cabins based on battery packs, but the battery energy storage system has insufficient power supply duration guarantee under the demand of high-power and high-current discharge.

In terms of oil-electricity coordinated control methods, most oil-electricity coordinated control methods based on electricity consumption rules rely on experience, are highly subjective, and have no obvious economical and energy-saving effects; the instantaneous optimization coordinated control method only considers the current use cost , there is no coordinated control of the overall situation, and the improvement of economy and energy saving effect is limited
