Description

Technical Field

[0001] This invention relates to the field of power grid dispatching technology, and in particular to a multi-energy complementary control system for source-grid-load-storage coordination of hydrogen, ammonia, and alcohol. Background Technology

[0002] With the advancement of "dual-carbon" goals and the explosive growth in the number of new energy vehicles, highway service areas, as key refueling nodes for new energy vehicles traveling across regions, are facing severe challenges in their energy security capabilities. This is particularly true for medium-sized highway service areas with a daily traffic volume of 8,000-12,000 vehicles, where the energy supply and demand imbalance is especially pronounced.

[0003] Existing service area power supply systems largely rely on a single municipal power grid, lacking effective energy storage buffers and multi-energy complementarity. When the grid capacity reaches its limit, charging piles frequently experience overload protection shutdowns, excessively long charging queues, and even grid tripping, failing to meet the rapid charging needs of vehicles entering and exiting under heavy traffic. Secondly, medium-sized service areas are typically equipped with distributed power generation facilities such as photovoltaics, but existing energy management systems lack intelligent dispatch mechanisms. During peak photovoltaic power generation periods, surplus electricity is often not effectively stored and is discarded; while during peak electricity price periods, it is necessary to purchase electricity from the grid at a high price, resulting in high overall operating costs for service areas and failing to fully leverage the substitution effect of clean energy; furthermore, the system cannot intelligently allocate fast and slow charging resources based on the vehicle's expected dwell time and battery status.

[0004] To address energy supply issues, some service areas have begun experimenting with new fuels such as hydrogen, ammonia, and methanol. However, existing monitoring systems are mostly designed for single media and lack unified safety monitoring of multi-media pipelines (electricity, hydrogen, ammonia, methanol, etc.). In high-density operating environments, if leaks, electrical faults, or pressure anomalies occur, the system may struggle to trigger timely warnings and shutdown mechanisms, posing significant safety hazards.
