A Sensitivity-Based Linear Model for Optimal Dispatch of Local Flexibility

Traditionally, the generating units connected at the HV level are the only providers of ancillary services. This is now extended to distributed resources connected at the MV/LV level. However, due to the huge number, it is hard to manage them directly in a centralized Ancillary Services Market. In this paper, an optimization tool to dispatch local flexibility according to regulated local market schemes is proposed. A MILP is formulated to integrate both continuous and discrete flexibility bids and the network constraints. The tool performance is evaluated on the 69 buses distribution grid.
