Abstract: With the in-depth advancement of new power system construction, explosive growth has been witnessed in distributed photovoltaic (PV) installations in Jiangsu Province, and the whole-village contiguous development mode has been accelerated. Consequently, higher requirements have been put forward for the carrying capacity and operational safety of distribution networks. This paper is focused on the construction of whole-village distributed PV development for low-voltage users. Seven development modes are compared in terms of their application scenarios, costs and benefits; a group control and dispatch architecture and an instruction interaction process have been constructed to achieve centralized management of PV systems in distribution transformer areas; fixed and floating packages as well as transaction processes for aggregators participating in the electricity market have been designed; and suggestions for whole-village development, including tripartite collaboration, energy storage optimization, digital and intelligent development, and policy mechanism innovation, have been proposed. These efforts provide technical and management references for whole-village contiguous development.
