12月28日，由浙江金華供電公司、浙江東陽市供電公司和華北電力大學合作研發的“多元配網低碳資源協同運行工具”，率先在東陽開展精準柔性負荷控制試點工作。該工具是集經濟、低碳和安全調度輔助決策于一體的“虛擬電廠”，借助其協同調控能力，可有效實現區域內負荷平衡，保障電力安全可靠供應。
On December 28, the "Collaborative Operation Tool for the Multi-Low-Carbon Resources of Distribution Network ", which jointly developed by State Grid Jinhua Power Supply Company, State Grid Dongyang Power Supply Company and North China Electric Power University, used in Dongyang for the first time with its function of precise and flexible load control. This Tool is considered as a “virtual power plant” that integrates economy, low-carbon and assisting the safe dispatch. With its coordinated control capabilities, it can effectively achieve regional load balance and ensure safe and reliable power supply.
為支撐甬金鐵路建設，東陽市松崗變電站自12月28日起配合計劃停電。據此前預測，江北和六石街道區域內用電高峰期間存在約2萬千瓦的負荷缺口，以此為契機，工具迎來了首次應用。試點過程中，工具依據此區域內的197家工業企業用電負荷情況一鍵生成錯峰用電計劃，監控企業實時負荷與計劃負荷的偏差，根據工具中預設的負荷預警偏差及時進行了告警，提醒調度、營銷等專業人員關注錯峰用電執行進程，較好地實現了需求側無感電力調度和計劃停電場景下錯峰用電業務全流程的數字化，達到了松崗變區域內電網“削峰填谷”的效果。
In order to support the construction of the Yongjin Railway, Dongyang Songgang Substation would cooperate with the planned power outage on December 28. According to the prediction, there would be a load gap of about 20,000 kilowatts during the peak period of power consumption in the Jiangbei and Liushi streets. Taking this as an opportunity, the tool was applied for the first time. During the application, the tool generated a peak-shift power plan based on the power load situation of 197 industrial enterprises in this area, monitored the deviation of the real-time load from the predicted load, and prompted an alarm based on the preset load warning deviation in the tool, reminding the dispatching and marketing staff to pay attention to the implementation process of peak shift, and realized the digitization of none perception power dispatch under the demand-side and peak shift of power consumption in the planned power outage scenario, optimizing the power supply in Songgang Substation area.
在試點應用中，供電所員工反饋以往的錯峰用電工作需要消耗大量精力選擇停電企業、約定停電時間、計算停電當日相關企業滿足負荷缺口所需可調負荷量，借助工具一鍵生成策略及負荷調整監視預警等功能，有效降低人力勞動，大幅度提升工作效能，實現了企業負荷調控的最優配置，創新探索了應用電力大數據支撐精細柔性負荷控制的高效路徑。
During the application, the staff of the local power supply station reported that peak shift of power consumption took them a lot of time in the past to select the blackout company, agree on the blackout time, calculate the adjustable load required by the relevant company to meet the load gap at that time. And using the tool to generate the strategy, monitor the load adjustment, etc. effectively reduce manpower, improve work efficiency, optimize the enterprise load control, and innovatively explore the efficient path of applying big data to support presice and flexible load control.
據了解，該工具還可通過負荷特征提取建立多元負荷主題特征庫，實現聚合分布式光伏、儲能、電動汽車充電站和工商業電力用戶負荷等可調負荷，構建電力用戶負荷畫像，根據調度目標一鍵生成負荷聚合單元，實現挖掘多元負荷調度潛力，智能編排日前計劃，支撐區域電網的平衡調控，為打造高彈性智能配電網打下基礎。
It is understood that the tool can also establish a multi-load theme feature library through load feature extraction to realize the aggregation of adjustable loads such as distributed photovoltaic, energy storage, electric vehicle charging stations, and industrial and commercial power user loads. And building a power user load profile according to scheduling goals to generate load aggregation units with one click to bring out the potential of multiple load dispatching. It can also intelligently arrange the day-ahead plan, support the balanced regulation of regional power grids, and lay the foundation for building a highly flexible and intelligent distribution network.
下一步，浙江金華供電公司將總結分析此次工具應用場景落地的經驗做法，持續優化完善工具功能。未來工具可根據電力營銷需求響應、電力調度和電力市場等業務需求，依托內置的經濟最優、碳排放最低、電力實時平衡等多種調度策略，有效支撐負荷的協同優化調度，壓降電網峰谷差，助力區域內雙碳目標的落地，支撐新型電力系統建設。
In the next step, State Grid Jinhua Power Supply Company will summarize and analyze the application results and continue to optimize and improve the tool functions. In the future, the tool can effectively support coordinated and optimized dispatch of loads and reduce power grid peaks based on built-in economic optimization, lowest carbon emissions, and real-time power balance strategies for business demands such as power response, dispatch and marketing, to achieve the carbon peak and carbon neutrality targets, in the region and support the construction of the new type of power system.
