The invention discloses an
energy storage charging and discharging monitoring and auxiliary decision-making method and
system under multiple time scales, and the method comprises the steps: carrying out the collection and
verification of the operation state of an
energy storage station group, and forming a chargeable / dischargeable capability surface based on the province-based and whole-network aggregation; a suggested target curve is generated on multiple time scales; when it is predicted that
new energy peak regulation blocking occurs in the
noon, the
system calculates the needed charging power; when a peak segment balance gap is predicted and displayed, the
system calculates a
discharge strategy; after the strategy is generated, checking the cross-section
tidal current and the climbing rate, and reserving the peak electric quantity of the next day in a cross-day scene; and the suggested curve lands according to the hierarchy of whole network-provincial-
zoning-
station. According to the method,
energy storage resources can be arranged in a unified manner in multiple time scales, multi-level landing can be oriented in a
master station platform, online rolling check is supported, and
new energy consumption, peak section guarantee supply and section safety are considered at the same time.
