The smart grid integrates advanced sensors, a twoway communication infrastructure, and high-performance computation-based control. The distribution management systems for smart grid include several functions for manipulating legacy voltage control devices and distributed energy resources through closed-loop volt/var control, leading to wide-area regulation of voltages in the presence of fluctuating power. The other primary distribution network analysis application is concerned with automatic fault location and service restoration following fault events, aiming to provide the grid with autonomous intelligence for self-healing. Communication technologies are vital to enable the computing applications of distribution networks, whether they work in centralized or distributed modes. This paper presents the state of the art in distribution management system architectures and modern workflows showing data exchange, practical parallel implementations designed to handle large amounts of data, in addition to communication standards that serve as interoperability enablers. It demystifies the relationship between different functions developed independently by power system researchers and shows their operation as a complete system, thus placing them in a better context for future research and development.

The distribution control center (DCC) has evolved from a sideshow in the traditional distribution service center to a major centerpiece of the utility moving into the decentralized world. Mostly, this is the place where much of the action is happening due to new forms of energy that are coming into the distribution system. This creates the flexibility of operation and increased complexity due to the need for increased coordination between the transmission control center and DCC. However, the US and European utilities have adapted to this change in very different ways. Firstly, we describe the research works done in a DCC and their evolutions from the perspectives of major US utilities, and those enhanced by the European perspective focusing on the coordination of distribution system operator and transmission system operator (DSO-TSO). We present the insights into the systems used in these control centers and the role of vendors in their evolution. Throughout this paper, we present the perspectives of challenges, operational capabilities, and the involvement of various parties who will be responsible to make the transition successful. Key differences are pointed out on how distribution operations are conducted between the US and Europe.
