This paper presents principal design structures for scalable distributed power systems (DPS) focusing on information flow and management enabling "plug and produce" capabilities. The purpose is a general structure that should be appropriate independent of system capacity. The main needs in future market and power system requires a feasible solution that is adequate in scalability and flexibility for managing a high degree of automated functionality. The basic solution is to automate and down-scale the common centralized structure for operating a power system to several DPSs that interact by well-defined hardware and software interfaces. This involves full decentralization that brings an increasing number of automated decision-makers decreasing the size of problems to be solved.
