A two-stage scheduler of distributed energy resources

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 twostage 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. ©2007 IEEE.
