Abstract: The ever increasing penetration of distributed renewable energy generating units imposes higher requirements for the power system， especially the distribution system. As one of the emerging market-based mechanism to coordinate distributed energy resources， transactive energy has provided a viable solution to accommodate a high penetration level of distributed renewable energy sources. Given this background， this paper focuses on transactive energy at demand-side and aims to examine appropriate mechanism design and analyze potential economic benefits. First， the overall framework of transactive energy is proposed， and the rules of energy transactions and market clearing procedures are introduced. The mathematical models of responsive demands are developed considering the characteristics of electric vehicles and controllable loads. Uncertainties are addressed through an analytic chance constrained programming reformulation method. On the basis of the presented transactive energy mechanism and demand-side models， an optimal bidding model is proposed. Finally， the effectiveness of the proposed model and method is demonstrated by case studies.
