山东电网冬季用电负荷首创新高

Core Viewpoint - The article highlights the challenges and measures taken by State Grid Shandong Electric Power to ensure stable electricity supply during the winter season, particularly in response to severe cold weather and increased demand for heating. Group 1: Electricity Demand and Supply - Shandong experienced its first large-scale rain and snow weather this winter, leading to a significant increase in electricity demand, with the highest load reaching 111 million kilowatts, a 4.7% increase compared to last winter's peak [1] - The company has implemented a "double removal" action to address the impact of snow and ice on wind and solar power generation, ensuring rapid recovery capabilities for 17 million kilowatts of installed wind and solar capacity [1][2] Group 2: Energy Storage and Grid Stability - The large-scale deployment of new energy storage has bolstered winter supply capabilities, with 144 new energy storage stations collectively discharging a maximum power of 8.389 million kilowatts, setting a new record for provincial grid energy storage [2] - The company has enhanced its grid's "anti-freezing" capabilities through infrastructure upgrades, including the successful energization of the 1000 kV Quanle double line, which mitigates risks associated with severe weather [2][3] Group 3: Equipment Maintenance and Monitoring - A total of 2,656 maintenance tasks for transmission and transformation equipment have been completed, including significant upgrades to high-voltage lines, ensuring robust support for winter operations [3] - The company employs a combination of manual and drone inspections to monitor critical transmission lines, enhancing the ability to detect potential issues in real-time [3] Group 4: Customer Management and Forecasting - The company has implemented a tagging management system for 3.65 million "coal-to-electricity" customers, utilizing a three-color warning mechanism to monitor electricity usage and manage outage risks effectively [4] - Forecasts indicate that the peak load for Shandong's grid this winter and spring will reach 116 million kilowatts during midday and 104 million kilowatts during the evening peak [4]
