The distributed energy management technology based on communication channels plays an important role in the economic operation of modern smart grid. However, information exchange between participating agents, such as multiple heterogeneous generation devices and consumption loads, increases risk privacy leakage, which will reduce optimization performance even result collapse whole system.
