Abstract: The current coordination between the transmission system operator (TSO) and the distribution system operator (DSO) is changing mainly motivated by the continuous integration of distributed energy resources (DER). The DER technologies are able to provide reactive power services helping the DSOs and TSOs in network operation. This paper follows this trend by proposing a methodology for the reactive power management by the DSO under renewable energy sources (RES) forecast uncertainty, allowing the DSO to coordinate reactive power services to the TSO. The proposed method entails the use of a stochastic AC-OPF, ensuring reliable solutions for the DSO. RES forecast uncertainty is modeled by a set of spatial-temporal trajectories. A 37-bus distribution grid considering realistic generation and consumption data is used to validate the proposed method. An important conclusion is that the method allows the DSO to take advantage of DER full capabilities to provide a new service to the TSO.
