Dataset

*Complete series data from January 1, 2016 to December 31, 2019 *35,064 hourly time-series observations for electricity generation from wind, coal, nuclear, and gas in GWh and, real-time locational marginal price sourced directly from the PJM market website *Combine hourly measurements of variables into 1,461 weighted average daily observations in line with the frequency of daily observations of natural gas prices *Daily Henry Hub natural gas prices for each trading day from January 1, 2016 to December 31, 2019 obtained from the U.S. Energy Information Administration (EIA). For days in which no trading took place (i.e., weekends and holidays), the most recent previous trading day values are used NG_Price = Daily natural gas price Actual_load_GWh = Daily actual electricity demand in GWh rtm_price = daily weighted average of real-time wholesale electricity prices Gas_GWh = daily electricity supply from gas in GWh Gas_pct = daily percent of electricity from gas Wind_GWh = daily electricity from wind in GWh Wind_pct = daily percent of electricity from wind Baseload_GWh = daily electricity from baseload sources (coal and nuclear) Baseload_pct = daily percent of electricity from baseload sources Rd_g_mln = estimated daily revenue in million U.S. dollars from natural gas Rd_w_mln = estimated daily revenue in million U.S.dollars from wind Rd_bl_mln = estimated daily revenue in million U.S. dollars from baseload sources Gas_UR = estimated gas unit revenue Wind_UR = estimated wind unit revenue Baseload_UR = estimated baseload unit revenue Gas_VF = estimated gas value factor Wind_VF = estimated wind value factor Baseload_VF = estimated baseload value factor

*2016年1月1日至2019年12月31日的完整时序数据集*
包含35064条每小时时序观测数据，涵盖风电、煤电、核电及天然气发电的发电量（单位：吉瓦时（GWh）），以及直接从PJM市场官网获取的实时节点边际电价（real-time locational marginal price）。
将各变量的每小时测量值合并为1461个加权平均日度观测值，以匹配天然气价格的日度观测频率。
2016年1月1日至2019年12月31日的各交易日每日亨利中心（Henry Hub）天然气价格数据，来源于美国能源信息署（U.S. Energy Information Administration, EIA）。对于无交易的日期（即周末与节假日），采用最近一个前序交易日的价格作为替代值。
NG_Price = 日度天然气价格
Actual_load_GWh = 日度实际电力需求（单位：GWh）
rtm_price = 实时批发电力价格的日度加权平均值
Gas_GWh = 日度天然气发电量（单位：GWh）
Gas_pct = 日度天然气发电量占总发电量的百分比
Wind_GWh = 日度风电发电量（单位：GWh）
Wind_pct = 日度风电发电量占总发电量的百分比
Baseload_GWh = 日度基荷电源（煤电与核电）发电量
Baseload_pct = 日度基荷电源发电量占总发电量的百分比
Rd_g_mln = 天然气发电业务估算日度营收（单位：百万美元）
Rd_w_mln = 风电业务估算日度营收（单位：百万美元）
Rd_bl_mln = 基荷电源业务估算日度营收（单位：百万美元）
Gas_UR = 天然气发电单位营收
Wind_UR = 风电单位营收
Baseload_UR = 基荷电源单位营收
Gas_VF = 天然气发电价值因子
Wind_VF = 风电价值因子
Baseload_VF = 基荷电源价值因子
