s4.1, entering a preset working mode;
s4.2, a strategy or a strategy group to be executed is pre-designated, the priority of the strategy or the strategy group is adjusted to be the highest priority, and the strategy is executed;
s4.3, selecting the optimal strategy and strategy group from the strategy library in advance, and executing the strategy or strategy group.
9. The operating method of the system for peak clipping, valley filling and energy storage management of the communication base station as claimed in claim 4 or 6, wherein the intelligent mode of the step S5 is operated as follows:
s5.1, entering an intelligent mode;
s5.2, acquiring current state information of the battery, a latest peak-valley electricity price table and standby electricity setting parameters from the data acquisition module and the data interaction module;
s5.3, the strategy generation module automatically generates a peak clipping and valley filling charge and discharge control strategy according to the information, marks the strategy as the highest priority and stores the strategy in a strategy library;
s5.4, executing the currently generated peak clipping and valley filling charge and discharge control strategy;
s5.5, continuously monitoring the state information of the battery, the peak-valley electricity price table and the change of the standby power control parameters, dynamically generating a new charge-discharge control strategy and executing the new charge-discharge control strategy;
and S5.6, automatically identifying the load mode, optimizing the standby power control parameters such as standby power duration, generating a new charge-discharge control strategy, and maximizing peak clipping and valley filling benefits.
