智能电网统一调度与高渗透率分布式能源协同编排
在可再生能源渗透率超80%的配电线路上实现动态潮流管控、状态估计与全自动电压无功(Volt-VAR)闭环优化。
实时配电网高精度状态估计(DSSE)
传统配网设计基于自上而下的单向潮流假设。而在高渗透率分布式能源接入下，必须采用加权最小二乘法(WLS)结合微型相量测量单元(Micro-PMU)，实时计算中压馈线的双向电压分布与相角漂移。
Key Engineering Requirements
- Sub-cycle state estimation operating at 60 Hz reporting rate over IEC 61850-9-2 Sampled Values
- Automated Volt-VAR Optimization (VVO) reducing distribution feeder losses by up to 4.2%
- Dynamic thermal line rating (DTLR) dynamically unlocking 15-30% extra capacity without conductor upgrades
- Four-quadrant smart inverter autonomous droop response complying with IEEE 1547-2018 Category B
