The invention discloses a power distribution strategy for energy consumption optimization of an energy storage power station, and the strategy comprises the steps: determining an output battery pack according to the obtained instruction power Ptarget and the health state SOH and the state of charge SOC of each battery pack in a current target energy storage power station; and inputting the state of charge (SOC) of each output battery pack into a pre-established target function which contains a constraint condition and can optimize a plurality of targets at the same time to obtain the output power P of each output battery pack, and distributing the output power P of each output battery pack to the corresponding output battery pack, wherein the multiple targets comprise the minimum power station energy consumption, the best power station economical efficiency and the longest power station service life and the constraint conditions comprise an instruction power Ptarget constraint, an output power P constraint of each output battery pack and a state of charge SOC constraint of each output battery pack. According to the method, the energy consumption, economy and service life of the power station are taken as optimization targets, and the energy efficiency of the energy storage power station under various working conditions can be effectively guaranteed to reach or approach the rated energy efficiency.
Description
technical field [0001] The invention belongs to the technical field of energy consumption optimization of energy storage power stations, and more specifically relates to a power allocation strategy for energy consumption optimization of energy storage power stations. Background technique [0002] With the transformation of my country's energy structure, the power system presents new features such as "high proportion of new energy" and "high power electronics". The proportion of thermal power units in the new power system has decreased, and the system inertia is insufficient, requiring a large number of flexible and fast adjustment resources. Energy storage is an effective means to solve the stability problem of the new power system, its scale is increasing, and its application scenarios are becoming more and more complex. For example, when the energy storage power station performs peak regulation response, its efficiency is about 85% under the rated state. When the energy ...
