Analyze the supply and demand situation and grasp the power supply and consumption situation. By the end of 2022, there will be 95 grid-connected power stations in Wuwei Power Grid, with a total installed capacity of 4401.42 MW. Among them, hydropower installed capacity was 162.33 MW, accounting for 3.69%; thermal power station installed capacity was 789 MW, accounting for 17.93%; wind power installed capacity was 1348 MW, accounting for 30.63%; photovoltaic installed capacity was 2102.1 MW, accounting for 47.76%. The annual maximum load of Wuwei Power Grid generally occurs in July, August, November, and December. July and August are the peak load periods for agricultural irrigation in summer, and November and December are the peak load periods for agricultural irrigation and heating in winter. From the perspective of industry, the power consumption of the primary industry and the secondary industry has grown rapidly, and the power consumption of the tertiary industry has grown steadily. The proportion of primary, secondary, tertiary industry and residential electricity consumption in the whole society is respectively: 3.27%, 64.58%, 21.43% and 10.72%. From the perspective of electricity consumption structure, industrial electricity consumption and electricity sales dominate, while the industrial structure is dominated by high energy-consuming industries. Judging from the current situation, in 2023, there will be a lot of new loads in Wuwei City, mainly external power supply loads and new high-energy-consuming loads on Lanzhang Lines 3 and 4, and power loads will be greatly affected by the high-energy-carrying industry market. Taking into account the market economy, the current natural increase in network load and the load reporting and installation situation of major power consumers, it is expected that the load and power consumption of Wuwei Power Grid will maintain a growth trend in 2023.
Strengthen load management and safely meet the peak summer. In accordance with the principle of "three guarantees and three promotions" of ensuring life, growth and stability, and promoting transformation, upgrading, and energy conservation, respond to power and power shortages that may arise at any time, promote the optimal allocation of power resources, and combine the city's actual power supply and demand , issued the "Wuwei City Peak Summer Load Management Plan in 2023", and compiled a six-level load management plan to effectively deal with the possible power load gap during the peak power consumption period in summer, and reduce the negative impact of the power supply and demand gap on the economy and society. To the minimum, effectively guarantee the people's livelihood, important users, and key enterprises' life and production electricity.
Carry out accident drills to improve the emergency response level. Further strengthen the forecast of power supply and demand balance, continuously improve the load management mechanism, technical standards and platform construction, and effectively improve the level of load management. On June 21, organized the "2023 Wuwei Power Grid to Prepare for Summer Peak and Electric Power Supply Joint Anti-Accident Drill" to exercise the ability to deal with sudden power grid accidents and improve the level of emergency management of emergencies. On June 22, the "Comprehensive Emergency Drill for Large-scale Power Outages in Wuwei City in 2023" was organized to comprehensively improve the emergency response capabilities for large-scale power outages, continuously consolidate the foundation of power safety production, and test the scientificity and reliability of Wuwei City's large-scale power outage emergency plans. Operability, effectively reduce the impact and loss caused by emergencies, and effectively protect the safety of people's lives and property.
