Robust hierarchical dispatch for residential distribution network management considering home thermal flexibility and model predictive control

Abstract

Abstract In the transactive energy (TE) paradigm, the devices of participative consumers, or prosumers, may be aggregated and employed to drive operational objectives at the network level. Home heating, ventilation and air‐conditioning (HVAC) systems in particular are well‐suited to modulate their behaviours based on both home thermal flexibility and requests from the utility grid. This paper develops a robust, hierarchical power dispatch scheme in the context of a residential distribution network. The formulation couples a unique, multiphase linear distribution optimal power flow (OPF) at the upper level with model predictive control (MPC)‐based HVAC fleet controllers at the lower level. The proposed approach is tested on nearly 2000 homes with a three‐phase distribution network in an intraday market setting, where two major applications are explored and analysed.
