针对现有5G基站储能参与配电网调控所面临的集中调控方法计算复杂度高、难以适配配电网负荷波动、无法感知基站储能电池能量与电池损耗等挑战,提出5G基站储能分布式自主调控架构,支撑5G分布式储能资源灵活接入配电网。在此基础上,提出一种基于电池状态感知上置信区间的5G基站储能调控算法,综合考虑基站储能电池容量约束与电池损耗成本,最大化储能调控效益和配电网负荷曲线方差的加权差,实现电池能量与电池损耗感知,辅助配电网削峰填谷。仿真结果表明:相较于现有2种对比算法,所提方法可以使基站储能调控效益与配电网负荷曲线方差的加权差分别提高12.73%和22.33%。研究成果能够很好地满足5G基站储能参与配电网削峰填谷的需求,实现配电网与5G基站储能双向互动。

利用四川及邻区数字地震台网2013—2018年的波形资料,基于CAP和HASH方法反演得到锦屏一级水电站(以下简称锦屏水库)库区及周边M_(l.≥2.5地震的震源机制解,根据DRSSI方法计算得到库区局部应力场信息,结合该区域的地质资料,从震源机制参数和局部应力场变化等方面讨论了水库加卸载对该区域地震活动的影响.取得的主要认识如下:(1)库区地震活动类型以走滑型为主,不同加卸载阶段震源机制类型存在一定差异,库区蓄水前期震源机制类型呈现多样性,蓄水后期与区域背景场趋于一致;(2)库区应力场最大主应力方向以NNW-SSE向为主,分时段结果显示,蓄水后期局部应力场最大主应力方向由NNW向逐渐发生偏转至NW向;(3)库区周边的地质构造和岩性条件有利于库水的渗透,蓄水后重力载荷和流体渗透的共同作用导致岩体断层面库仑应力的变化,从而呈现出库区蓄水前后中小地震活跃程度的显著差异特征.

We anal.zed the germination traits (germination rate, germination potential. and germination index) of seeds from 23 hal.-sib famil.es of birch (Betul. pl.typhyl.a). The germination rates of the 23 famil.es ranged from 38.57 to 76.50%. Seeds from the eight famil.es germinating at the highest rates were then used for germination experiments under sal. stress. Germination rate, germination potential. and germination index of these eight hal.-sib famil.es decreased with increasing sal. concentrations. The effects of four different hormones (6-benzyl.minopurine, 6BA;gibberel.in, GA3;naphthal.ne acetic acid, NAA;and mel.tonin) at various concentrations on the germination of seeds from the eight hal.-sib birch famil.es under sal. stress were investigated. Treatments with 6BA and GA3 al.eviated the effects of sal. stress on seed germination, whereas treatments with NAA and mel.tonin aggravated the effects of sal. stress. The most effective treatments for al.eviating the effects of sal. stress on birch seed germination were 10 mg/l.6BA and 300 mg/l.GA3. This study provides practical.information for screening birch famil.es for sal. tol.rance at the seed germination stage, and for cul.ivation of birch in sal.ne environments.
