A User-Friendly Transactive Coordination Model for Residential Prosumers Considering Voltage Unbalance in Distribution Networks

Abstract

Designing transactive energy (TE) markets in distribution systems has been a hot topic due to the increased presence of residential prosumers. In the literature, several residential market platforms have been proposed; however, they usually have two main drawbacks: 1) ignoring the effect of single-phase distributed energy resources on the voltage unbalance (VU) in active distribution networks to develop a transactive coordination model that will effectively mitigate the VU and 2) inability in providing a user-friendly strategy for home occupants to adjust the willingness to pay/accept of responsive assets according to their comfort and economic purposes. This article amends the shortcomings by proposing a network-constrained TE model to coordinate residential prosumers with the main goal of satisfying households’ preferences as well as mitigating distribution system problems. The case study is then carried out demonstrating that the proposed TE-concept-based coordination of residential prosumers is aligned with customers’ preferences (comfort and economic purposes) and concerns (plug-in electric vehicle battery life) and could effectively decrease the VU.
