Operating envelopes for prosumers in LV networks: A weighted proportional fairness approach

Abstract

Residential consumers with distributed energy resources such as solar PV and batteries, also known as prosumers, are becoming increasingly common. This, in turn, has created the opportunity to provide system-level services through aggregators. However, as the number of residential prosumers providing services increases, low voltage (LV) network constraints must be considered. This paper explores the use of day-ahead, time-varying operating envelopes (limits) calculated for each prosumer with an Optimal Power Flow (OPF) that incorporates the constraints of three-phase LV networks. The concept of weighted proportional fairness is adopted and implemented through the maximization of a logarithmi..
