Microgrid is well known as key technology to improve renewable energy's ease of use. Some previous works focused on a microgrid that is divided into autonomous electricity subsystems (AESs) for its reliability and scalability. We have proposed the MCMC-based autonomous decentralized mechanism (ADM) to perform energy interchange between AESs so as to be supply energy appropriately for different energy demands among AESs. In this paper, toward resilient of microgrids, we design a method to realize directional energy interchange in our ADM on the basis of the convection diffusion. We investigate the effectiveness of the proposed method through simulation experiment considering energy shortage and emergency situations. We clarify that the proposed method can fast supply energy from external power grid to a microgrid under energy shortage situation, and can fast gather distributed energy to a specific AES (e.g., safe shelter) under emergency situation.
