Abstract :
[en] Distributed energy resources (DERs) are transforming power networks, challenging traditional operational methods, and requiring new coordination mechanisms.
To address this challenge, this paper introduces SecuLEx (Secure Limit Exchange), a new market-based paradigm to allocate power injection and withdrawal limits that guarantee network security during time periods, called dynamic operating envelopes (DOEs).
Under this paradigm, distribution system operators (DSOs) assign initial DOEs to customers.
These limits can be exchanged afterward through a market, allowing customers to reallocate them according to their needs while ensuring network operational constraints.
We formalize the SecuLEx mechanism and illustrate DOE allocation and market exchanges on a small-scale low-voltage (LV) network, demonstrating that both procedures are computationally tractable.
In this example, SecuLEx reduces renewable curtailment and improves grid utilization and social welfare compared to traditional approaches.
