This tool will support the DSO on the procurement of ancillary services (for voltage control and congestion management) to mitigate renewables uncertainty and ensure that the network capacity is never exceeded during the real-time operation stage. The outputs of the TSO/DSO coordination mechanisms that will run in parallel with the market simulator will define constraints for this tool to avoid that TSOs and DSOs procure conflicting ancillary services in the markets.

This  tool optimizes the activation of flexibility, provided by both DSO assets (e.g. stationary storage and OLTC) and procured by the DSO in the ancillary services market, using the day ahead operation planning tool. The goal is to maintain the distribution network operating in a safe mode when forecasting errors occur, while minimizing OPEX and reducing environmental impacts

Even in the future energy systems, where communication technologies are expected to be much more developed and communication-enabled devices prominent, communication failures may still occur, preventing an accurate definition of the network operating state due to missing data. The coverage of distribution networks is a particular challenge due to their scale. This  tool will allow estimating the operating state of the network with minimal available information (by estimating the net load in each node of the grid) and thus enable the usage of all the tools developed for networks operation even when there is lack of data.

This tool is an evolution of the conventional Deterministic Security Constrained Optimal Power Flow (SCOPF), which will be enhanced to be a multi-temporal SCOPF under forecast uncertainty. The tool will enable the TSO to procure ancillary services (congestion management, voltage control and frequency control) on a 24-h ahead basis. Additionally, the TSO/DSO coordination mechanisms will be used together with this tool to avoid that TSOs and DSOs procure conflicting ancillary services in the ancillary services markets.

This tool will be used to optimize the activation of flexibility, provided by both TSO assets (e.g. stationary storage and capacitors banks) and procured by the TSO in the ancillary services market, using the day-ahead operation planning tool. The goal is to maintain the transmission network operating in a safe mode when forecasting errors occur, while minimizing OPEX and reducing environmental impacts.

This tool will perform a security assessment of transmission networks considering both static (i.e. voltages and currents) and dynamic constraints (i.e. stability) violations caused by N-1 contingency analysis.
