INTRODUCTION: High-ratio distributed energy resources (DERs) impact distribution network operation and require effective scheduling. IEC 61850 7-420 defines a DER model, but massive small/medium DERs in low-voltage networks hinder station-area aggregated management.
OBJECTIVES: Enable aggregated management, dynamic scheduling of small/medium DERs and ensure DER data security.
METHODS: 1. Analyze station-area structure and information needs via cluster control
2.Establish a general information model of DER equipment.
3.Build a new communication security control logical node
4.Realize the source-side dynamic conversion of inverter data
RESULTS: Key results: 1) IEC 61850-based DER scheduling model; 2) DER data security logical node; 3) Inverter data protocol conversion.
CONCLUSION: The proposed model, node and method resolve core DER management issues, providing a feasible distribution network scheduling solution.
