Xining, Xinhua, China, May 4 (Li Jiangning, Yang Baozhu) On May 4, a reporter learned from State Grid Qinghai Electric Power Company that as of the end of the first quarter of 2020, the total installed capacity of Qinghai New Energy Power Generation reached 16.09 million kilowatts, accounting for The province ’s total installed power generation capacity is 50.48%, making it the first province in China to have a 50% installed capacity of new energy.
Qinghai is endowed with abundant wind, light, and hydropower resources, and has become the most concentrated area for large-scale grid-connected photovoltaic power plants in the world. As of the end of April, Qinghai ’s new energy power generation increased by 17.36% year-on-year, and the province ’s new energy daily maximum power generation reached 96.7 million kWh, a record high.
"Since the first-level response to the public health incident in Qinghai started on January 25, the industrial and commercial load in the province has been reduced, and some enterprises have further shut down, resulting in a load reduction to 8.2 million kilowatts. At the same time, the load in the affected provinces has declined, and there is no demand for electricity purchase in each province. The consumption capacity outside the province has been reduced by 1.8 million kilowatts. "Peng Jianhua, Director of Marketing Department, Marketing Department, State Grid Qinghai Electric Power Company, introduced.
In order to reverse the unfavorable situation and help the new energy enterprises to speed up the recovery and stabilize, the State Grid Qinghai Electric Power Company has made full efforts to study and innovate and innovate the dispatching model to improve the consumption capacity.
According to Wang Maochun, chief engineer of the control center of Qinghai Electric Power Company of State Grid, the innovative dispatch model includes four measures: optimizing the coordinated and complementary control of water, fire, wind, light, and energy storage, comprehensive use of natural complementation of wind and light, and cascading adjustment of water elevators 1. Thermal power depth peak shaving, energy storage peak shaving and valley filling, to make room for new energy consumption, the utilization rate of the outgoing channels within and between provinces during the outbreak of new energy reached 98%, and the efficiency increased by 3% year-on-year.
Add power big data analysis module to power generation forecasting and load forecasting system, accurately calculate short-term and ultra-short-term surplus power of new energy based on historical and contemporaneous massive data source data, and improve spot trading before and within the day, except March The power transmission increased by 11.5% year-on-year.
At the same time, make full use of the time difference between Xinjiang and Shaanxi to carry out real-time replacement, timely adjust the direction of power delivery, and send the surplus photovoltaic to Xinjiang before 11 o'clock and east to Shaanxi after 16:00 to broaden the capacity of photovoltaic power generation period. In April, a total of 92.69 million kWh of power generation was added; 306 shared energy storage market transactions were carried out using blockchain technology, and more than 20,000 pieces of blockchain transaction certificate data were stored, and an additional 5.526 million kWh of new energy was issued.
According to Wang Maochun, chief engineer of the State Grid Qinghai Electric Power Company Control Center, in the second half of the year, the development of Qinghai New Energy will usher in explosive growth. State Grid Qinghai Power has begun to control the scale and timing of new energy installations to ensure the province The grid and the Qingyu DC were completed and put into operation on schedule, and actively responded to the development of the market within and outside the province to effectively support the construction of the Qinghai Clean Energy Demonstration Province.
