•A multi-VPP energy-sharing model is proposed based on GNB theory.•The network transmission cost encourages the consumption of renewable energy nearby.•The non-convex GNB-based model is divided into two sub-problems by transformation.•A distributed method based on the fast-ADMM is developed.•A contributing factor for profit distribution is applied to endorse renewable energy.
