Flexibility Pricing in Distribution Systems: A Direct Method Aligned with Flexibility Models
We then propose a flexibility cost formulation aligned with the aggregated flexibility model and design a DSO flexibility market model to activate the aggregated flexibility in the distribution system to participate in the transmission system operation for energy arbitrage and ancillary services provision.
