The paper presents a two-stage scheduler for the optimal scheduling of distributed energy resources (DER) connected to a distribution network. The proposed approach integrates a centralized day-ahead scheduler with an intra-day one. On the one hand, the day-ahead scheduler calculates the active power set points during the following day taking into account both technical and economic objectives and constraints. On the other hand, the intra-day scheduler takes into account the results of the day-ahead one and updates every 15 minutes the DERs set points for the optimization of the network voltage profiles. The paper describes the implementation of the proposed two-stage scheduler algorithm into a computer code based on a JavaScript link between Matlab and EMTP-RV simulation environments and presents the results obtained for the case of a network configuration adapted from the IEEE 34-node test distribution feeder.
