GB/T 39119-2020 in English

This standard constructs a pan-energy network collaborative control system that includes pan-energy stations, energy storage stations, and transmission and distribution systems, and proposes a four-layer architecture (network level/block level/station level/collection control layer) and six core functional modules to achieve the goals of energy system economy, energy saving, and environmental protection through multi-energy complementary optimization.

1. Multi-energy flow collaborative modeling

Use the CIM common information model to realize unified modeling of gas/electricity/heat/cold, with the following requirements:

• Data collection frequency: electricity ≥1 minute, thermal power ≥15 minutes
• Model accuracy: load prediction error ≤8% (short term)

2. Forecast function implementation

Establish a four-dimensional prediction system:

• Ultra-short term (within 1h): used for real-time control
• Short term (24h-7d): formulate daily plans
• Medium term (January-December): Maintenance planning
• Long term (1-5 years): Strategic investment

Industrial park case: Through block-level optimization:

1. Peak-valley arbitrage of photovoltaic + energy storage
2. Multi-energy complementarity of waste heat boiler and electric refrigerator
3. Demand response load adjustment range reaches 15%

1. Phase-based construction path: First complete the station-level automation transformation, and then build a block-level optimization platform

2. Key indicator monitoring: Continuous tracking is required:

• Comprehensive energy efficiency improvement rate (target ≥12%)
• Renewable energy consumption rate (target ≥85%)
