Architecture-Oriented Assurance Technology in Microgrid

This paper presents a discussion on architecture-oriented assurance technology in Micro grid. We analyzed the characteristic of Micro grid from evolutional view, and proposed the concept of architecture-oriented assurance technology in Micro grid from the technology evolution and policy evolution. Technology evolution contained Function Evolution, Role Changing Autonomy and Role Coordination. Policy evolution included evolution of market rules, price mechanism and management mode. Meanwhile, we proposed two kinds of policy based on role of DER (Distributed Energy Resources). Moreover, we proposed a coordinated control strategy frame based on Role Autonomous Decentralized System (Roads) and its architecture. We defined different roles of Photovoltaic array (PV) DER, constructed the configuration files of PV DER and clarified the driven process. This frame was expected to achieve coordinated control for Microgrid.
