Active household energy storage management in distribution networks to facilitate demand side response

This paper tries to devise a methodology for managing domestic electric energy consumption with storage devices in distribution networks. Following a brief introduction to the current demand side response (DSR) features and assessment of electricity demand, an analytical approach for shifting demand from peak to off-peak periods is developed by utilizing the household energy storage. A comparative study is thereby carried out to investigate the impacts of different charging and discharging scenarios under three types of wholesale energy prices, i.e., conforming price, volatile price and conflicting price. The benefits of the load shift caused by introducing household storage devices can be reflected as wholesale cost saving for customers and network investment deferral for system operators. A typical UK household load profile is adopted as an example to demonstrate the impact of the proposed energy storage control strategies on the benefits.
