Dataset to Study TSO-DSO Coordination Market Models for Flexibility Procurement to Balancing and Congestion Management

The dataset is composed by an interconnected system consisting of the IEEE 14-bus (TN) transmission network connected to three distribution networks: the Matpower systems 18-bus (DN_18), 69-bus (DN_69), and 141-bus (DN_141). All systems topology and some parameters are based on the corresponding cases in Matpower [1]. Base demand is adapted from the case, while base generation profiles are added to all nodes. All distribution systems are balanced, and the transmission system is imbalanced. Thermal limits of the lines are adapted in order to create congestion in the systems. Each distribution system is connected to the transmission system through one line, which has capacity of 1.0. The interconnected system is fully represented in "Network.xlsx", in which: System: transmission (TN) or distribution (DN_18, DN_69, DN_141); LineID: ID of the lines; BusNumber: number of the nodes within the systems. This parameter is used to define the lines (from/to); BaseDemand and BaseSupply: base active demand and generation of each node; ConnectedDN: distribution system to which the transmission system node is connected to. If blank, the node is not connected to any distribution system. Only for the transmission system; InterfaceCapacity: thermal limit of the interface between the transmission and distribution systems; ThermalLimit: thermal limit of the transmission/distribution systems lines. For distribution systems, a value of 10 indicates that the line has no limit; SFTN: shift factor matrix of the transmission system. Capture the change in the active power flow over a line due to a change in injection or offtake at a node; BaseReactiveDemand and BaseReactiveSupply: base reactive demand and generation at each node. Only for distribution systems; VoltageLB and VoltageUB: lower and upper limits for the magnitude squared of the voltage in each distribution system node. Only for distribution systems; ConnectedTN: identify if the distribution node is connected or not to the transmission system. Only for distribution systems; ResistanceR: resistence of the distribution system lines. Only for distribution systems; ReactanceX: reactance of the distribution system lines. Only for distribution systems. Flexibility bids are randomly generated in the different nodes. For downward flexibility bids, the prices are drawn from the uniform distribution in the range 10 to 15, and for upward flexibility bids, they are drawn from the range 45 to 50. The bids maximum quantities are genera
