The paper aims to provide an outline of energy-efficient solutions for base stations of wireless cellular networks. However, these storage resources often remain idle, leading to inefficiency. Key industrial players have recently shown strong interest in incorporating energy storage. . We mainly consider the demand transfer and sleep mechanism of the base station and establish a two-stage stochastic programming model to minimize battery configuration costs and operational costs. To transform the uncertainty expression in the first stage into a deterministic model, we design the. . Soft energy saving mode refers to that software can flexibly turn off part of devices or carriers according to cell load (performance data) to save energy on the basis of satisfying certain wireless performance [1].
