DLMP-Based Quantification and Analysis Method of Operational Flexibility in Flexible Distribution Networks

With high penetration of flexible resources, operational flexibility distribution networks (FDNs) is important to ensure high-quality electricity services. This paper proposes a value quantification and analysis method for in FDNs based on locational marginal pricing (DLMP). First, constraints are formulated from the perspective node integration, branch transfer, network aggregation flexibility. Then, unified analytical framework quantifying established, which spatial-temporal transfer modeled with derivation sensitivity factors. Further, DLMP-based model proposed nodal net power as unit pricing. The obtained price can not only quantify but also be used guide resources. Finally, effectiveness validated modified IEEE 33-node system 123-node system. Results verify that impact effectively improve overall performance through price.
