The invention relates to the technical field of
electric power energy storage control, and discloses a multi-dimensional state driven
energy storage cold
energy storage optimization
control system and method, and the method comprises the steps: collecting the multi-dimensional state parameters of an energy storage
system and the price of an
electric power market, and judging a current
operation time period mode; in the active
cold storage mode, target
cold storage capacity is determined according to the maximum allowable
heat capacity buffer margin, and cold pre-storage is completed; in the cold capacity release mode, cold capacity-
heat capacity collaborative multi-stage judgment is executed, the minimum critical
mass flow rate meeting the heat exchange requirement is reversely solved, the minimum critical
mass flow rate is mapped to a discrete control gear of the liquid cooling
circulating pump to generate a final rotating speed instruction, and meanwhile closed-loop flow correction is executed; according to the method, the minimum critical
mass flow rate is accurately solved, the rotating speed of the liquid cooling
circulating pump is remarkably reduced while battery
thermal inertia buffering is utilized, parasitic
energy consumption is greatly reduced through the cubic relation between pumping
power consumption and the rotating speed, and the problem that
electric charge income is counteracted due to excessive pumping is solved.
