State Grid Zhejiang Electricity: Deep excavation of potential to improve power supply capacity

On August 8th, Zhejiang Jiashan County Power Supply Company enabled the Yangtze River Delta integrated power supply agreement to support mutual assistance agreements, using 35 kV and 10 kV inter -provincial liaison line to receive electricity from Qingpu District, Shanghai to ensure the supply of county power. This is the first time that Zhejiang Province has received foreign electricity through the distribution network. It is understood that from August 8th to 15th, Qingpu District, Shanghai, averaged 10,300 kilowatts of electricity in Jiashan County.

Since the summer, Zhejiang has continuously and high temperatures, superimposed economic recovery to release power demand, and the province's power supply situation has been complicated. Faced with the challenge, State Grid Zhejiang Electric Power Co., Ltd. proposed the principle of "adhere to the priority of protecting the priority, exerting market advantages, and keeping the security bottom line", formulating a package of "increasing extra -expansion and internal expansion, migrating peak -filled valley", and deeply excavating power supply potential. Improve power supply.

"In order to give full play to the maximum power supply capacity, we continue to optimize the scheduling to ensure that the units in the province are full." Wu Huahua, deputy chief engineer of the Zhejiang Power Scheduling Control Center, introduced that the maximum power of the coal -fired units in Zhejiang Province this summer is 42 million kilowatts, and The maximum force of the gas unit is 9.17 million kilowatts.

In the summer, the light is sufficient. The State Grid Zhejiang Power Digging has deeply dig the potential of photovoltaic power generation. It uses the regulatory methods such as pumping energy storage and new energy storage, and uses digitalization methods to release new energy power generation capabilities to the greatest extent. Data show that this summer Zhejiang photovoltaic force exceeds 11 million kilowatts.

Zhejiang Province is rich in hydropower resources, and the State Grid Zhejiang Power Science Arrangement arrangements to accurately release water at the predetermined rhythm at the predetermined rhythm. In the province, the company optimizes the scheduling of more than 2,500 water power stations to improve the peak adjustment capacity by 1 million kilowatts.

On July 8th, ± 800 kV Ling Shaot's high -voltage DC transmission project entered a full power operating condition, sending coal power and wind power of Ningxia Energy Base to Zhejiang to ensure the supply of Zhejiang power. State Grid Zhejiang's electricity multi -measures, with the help of high -voltage and 500 kV inter -provincial connection lines, actively use medium- and long -term transactions, provincial spot transactions, and East China auxiliary service markets to achieve the flexible adjustment of cross -regional transactions in real -time power transactions a few days ago, and make full use of the market. The mechanism improves power confession. Since the summer of this year, the highest transaction electricity on the Zhejiang Power spot market trading day is 6.99 million kilowatts.

In addition, State Grid Zhejiang Electric Power actively explores the replacement of power replacement. At 15:30 on August 9th, as 500,000 kilowatts of electricity from Anhui was sent to Zhejiang through East China Power Grid, Zhejiang and Anhui launched the 43rd power replacement of electricity in this summer. The two parties use the maximum power load time difference to achieve mutual support for electricity. State Grid Zhejiang Electric Power also increased the medium and long -term power of Fujian through weekly transactions, and implemented a 500,000 kilowatt power supply of Zhejiang during the daily peak hours.
