Five new energy indexes of northwest power grid have all reached new highs
According to the northwest branch of state grid co., LTD., the generating capacity of new energy in the northwest power grid reached 787 million kilowatt-hours on April 25, accounting for 32.39% of the total power generation and 44.35% of the total power consumption of the whole network on that day. Among them, wind power has the largest generating capacity of 32.93 million kw, generating 621 million KWH. The five new energy indexes of northwest power grid have all reached new highs.
It is reported that the theoretical generating capacity of this new energy day reached 888 million kilowatt-hours, and the maximum amount of wind power in the evening peak was 32.93 million kilowatts, both of which were the highest single-day levels in history. The northwest branch of state grid overcame the adverse influence of the important new energy power supply channel maintenance and other problems in the network, made full use of the new energy flexible scheduling mechanism, planned ahead, and took multiple measures to improve the consumption level of new energy power generation.
According to the forecast, the forecast accuracy of the northwest power grid's new energy day-ahead theoretical power generation is 99.4%, and the forecast accuracy of the evening peak wind power is 97.4%, which provides the basis for the arrangement of the power grid operation mode.
The northwest division of state grid arranged 23 times for the shutdown and peak-load adjustment of thermal power units with a capacity of 8.34 million kilowatts through the backup coordination of large power grid. The negative standby capacity of conventional power supply was reduced to -12.73 million kilowatts, and the new energy capacity was increased to 96.84 million KWH. Communicate with the national power dispatch and control center of state grid co., LTD., reduce the restriction of 600,000kw on the dc power of jiquan by adjusting the operation mode of jiquan dc. The application of intelligent coordinated control system, automatic coordination of all kinds of power supply output, 750 kv sand fish line, pull the official line during the maintenance of the network important section utilization rate of more than 95%.
At the same time, the northwest branch of state grid carried out a total of 46 transactions and auxiliary services, increasing the consumption of new energy by 58.37 million KWH.
