@niccruzpatane 指出黄仁勋用英伟达股票为其父母购买 1999 年款奔驰 S 级轿车，价值约为 8 万美元。 如果按照英伟达当前市值计算，这辆车价值约为 12 亿美元，增长 15000 倍。 黄仁勋强调，相比于股市波动，他更关注行业基本面。他认为，在超大规模云计算厂商 （Hyperscalers）的推动下，全球目前正经历"人类历史上最大规模的基础设施建设"，而这仅仅是开 始。 针对 AI 行业的未来发展，黄仁勋指出，目前的建设投入已达数千亿美元，但未来需求仍高达数万亿美 元。他解释称，这种大规模投入完全合理，因为 AI 模型需要处理海量语境信息，才能生成驱动上层应 用所需的智能。 随着前沿模型和代理式 AI（Agentic AI）的兴起，市场对底层算力的需求将持续爆发。目前的挑战在 于，这些大规模投资能否有效转化为广泛且持续的技术应用。 来源：IT之家 在达沃斯世界经济论坛（WEF）对话贝莱德（BlackRock）首席执行官拉里 · 芬克（Larry Fink）时，英 伟达首席执行官黄仁勋透露，其公司上市后曾以 3 亿美元估值出售股票，只为给父母购买一辆梅赛德斯 S 级轿车。鉴于英伟达目前市值已逼 ...

王旭阳指出，当前电力系统已呈现潮汐式往复的运行特征，这对系统安全稳定机理带来新变化，主网、 配网、微电网协同运行成为核心技术原则。未来需在强化分布式电源本地消纳的基础上，依托整个电力 系统实现全局平衡与优化，通过主配微协同机制适配新能源发展新态势。 面对新形势下的发展诉求与挑战，王旭阳强调，分布式新能源的有序发展需依托电网整体资源平台，核 心要围绕三大要素精准发力——系统消纳能力、调峰与灵活调节能力、区域负荷水平，这三大要素直接 决定了未来分布式电源的承载规模与接入布局。基于此，国网经研院对分布式电源承载能力评估方法进 行了系统性优化与调整。 此次优化重点体现在两大维度。一方面，新增系统级承载能力测算，同时回归电网设备本身，在保障安 全运行的前提下，对220千伏电网反送电约束进行适度放宽。王旭阳明确，新约束标准为潮流不超过并 列运行变压器的50%、分裂运行变压器的80%，以此防范反向重载或过载风险，兼顾新能源接入需求与 电网安全底线。这一调整充分考量了系统整体消纳能力与分布式电源"可观、可测、可调、可控"的推广 需求，突破了以往的刚性限制。 另一方面，评估方法实现从单一值到区间化的升级。王旭阳表示，传统承载率 ...
