当您参加测验时，就会出现答案和解释。

  1. According to the U.S. Energy Information Administration, what can happen if grid supply and demand fall out of balance?
    • Local or widespread blackouts can occur
    • The grid automatically converts to a battery
    • The nominal AC frequency increases permanently
    • All electricity meters stop recording permanently
  2. According to NREL’s renewable-integration report, why can wind and solar generation vary over time?
    • Their output is fixed by monthly billing cycles
    • Their output changes with time of day and weather patterns
    • Their output depends only on utility office hours
    • Their output is determined solely by the number of PMUs
  3. Which resources does DOE list as examples that may be part of a virtual power plant?
    • Only one large coal plant
    • Only transmission towers and substations
    • Distributed resources such as rooftop solar and battery storage
    • Only residential energy bills
  4. Besides their reporting rate, what kind of electrical measurements do PMUs provide for grid monitoring?
    • Only monthly energy bills from customer accounts
    • Only unsynchronized daily temperature averages
    • 仅限发电站名称
    • 时间同步电压和电流相量，带频率相关估计
  5. 当逆变器基础资源取代部分同步发电机时，哪种固有的电网响应可能会降低？
    • 同步机传统提供的转动惯量
    • 客户表计数量
    • 光纤链路中的光速
    • 电网的额定交流频率本身
  6. NREL 的 dsgrid 工具包使用哪些维度来建模电力需求？
    • 仅限电厂名称和所有权
    • 时间、地理位置和最终用途
    • 仅限客户姓名和账单地址
    • 仅限市场价格，不含负荷数量
  7. FERC 2222 令令牌化分布式能源资源聚合实现什么？
    • 自动豁免所有公用事业和市场规则
    • 直接向任何家庭销售电力，无需运营商
    • 参与有组织的批发电力市场，受适用规则和协调约束
    • 用 AI 替代输电运营商
  8. 根据 DOE 的入门指南，PMU 同步相量数据大约可以以何种速率报告？
    • 每月一次测量
    • 每天一次测量
    • 每五年一次测量
    • 每秒 30 次或更多测量
