The global potentiostat market covers electronic instruments that are used for controlling the voltage difference between working and reference electrodes contained in electrochemical cells. These instruments are used for performing electrochemical experiments. The potentiostat injects current into the cell using an auxiliary or counter electrode, which helps in controlling the difference in voltage.

NGLs are a group of hydrocarbons that are typically found in natural gas streams but exist in a liquid state at atmospheric pressure and temperature. They are often produced in conjunction with natural gas and crude oil.

站在投资的角度，决定股票价格的无非是估值和盈利两个因素，相对于估值的频繁波动，盈利则更加确定一些；目前市场上主要证券公司研究机构对于行业业绩的预测有两种研究方法，一部分机构倾向于主观判断，一部分机构则采用自下而上的研究方法；两类方法存在一定的缺陷，例如，盈利预测存在主观性，盈利预测的时间跨度较大，预测并不能跟随宏观经济、政策的变动及时做出调整，导致行业拐点的把握不够及时准确。

2023 年 1-11 月储能板块累计下跌 30.6%，跑输大盘（沪深 300 指数 下跌约 10%），后续盈利确定性较强的海外大储和工商储为核心投资主线。年初以来，储能板块持续下行，市场担忧国内大储后续盈利能力；美国储能需求受并网延期影响，后续需求存在一定不确定性，以及海外户储库存较高，企业出货短期承压。展望 2024 年，我们认为重点把握两条主线：1）盈利确定性：电芯价格低价企稳趋势下，核心关注盈利确定性高的海外大储和工商储赛道；2）业绩改善：关注海外户储库存去化时点，叠加 23H2 户储板块公司基数相对较低，24H2 户储公司业绩端或具备弹性。

Automatic generation control, a type of decentralized control system, is used to maintain system frequency and to track load variations. Also, it aids in maintaining optimal power generation, which proximate the scheduled power generation value. In automatic generation control, when utilities are connected together, each of these utilities will perform this automatic generation control function independently.
