The invention discloses a power
system new energy power station matched
energy storage reasonable scale calculation method and
system, and the method comprises the steps: carrying out the hour-level production
simulation with the lowest operation cost as an objective function for a target power
system, and calculating the total
new energy annual energy output and
energy storage power consumption of the target power system; carrying out production
simulation on the target power system comprising the incremental
new energy power station, measuring and calculating the total new energy annual energy output and the
energy storage loss
power consumption of the target power system, and calculating the true cost per kilowatt-hour of the incremental new energy
power station; a unit energy storage scale is given, annual cost converted by
total investment and operation maintenance cost is calculated, and different energy storage scale sequences are obtained through sorting from small to large; and performing production
simulation on the power systems under different energy storage scales contained in the energy storage scale sequence, calculating the energy storage cost per kilowatt-hour of the increment new energy power
station one by one, and comparing to obtain the optimal matched energy storage scale. The method can help the increment new energy power
station to measure the reasonable scale of matched energy storage, and achieves the maximization of the income of the power
station.
