Resilient residential energy management with vehicle-to-home and photovoltaic uncertainty

Abstract

Resilient operation of residential buildings is an emerging topic. This paper proposes a resilient home energy management strategy to enable residential houses to implement self-power supply during a planned grid outage period. The proposed strategy utilizes the energy backup capability of plug-in hybrid electric vehicles (PHEV) to accommodate residential solar photovoltaic (PV) source and power the house in the presence of grid outage event. The proposed method also harnesses the load shifting flexibility of the smart home through a user disutility model. A stochastic programming approach based on Wasserstein distance metric and K-medoids based is applied to handle the residential photovoltaic solar power uncertainty. Simulation results show the proposed method can effectively enhance the residential resilience.
