An open design approach for distributed energy management systems

Abstract

EMS design has traditionally been a top-down process, in which a single vendor provides the algorithms, software and hardware to meet the utility's functional specifications. Recent trends in power systems, such as the move by utilities to Open Systems architectures, and the development of distributed computing systems indicate that this process must be changed to incorporate the new expertise required in EMS design. We propose an Open Design Approach to accomplish this. Our design approach is based on decomposing the EMS design problem according to different levels of abstraction. We define the components of this decomposition and discuss their relationships. These components form the conceptual design for a CAD simulation package which is being developed at UC Berkeley to evaluate and compare the performance of alternative designs.

Leveraging Computational Grid Technologies for Building a Secure and Manageable Power Grid

“…The ability to communicate and share information with other parties (e.g., other control centers, RTUs, market participants, large customers and suppliers, control center service providers) is required due to changes in business models and for achieving system wide reliability [27]. However, the presence of proprietary data formats as well as proprietary vendor-specific hardware and software make this communication challenging [17].…”

DYMONDS computer platform for smart grids

“…If the electric power grids are to become much more autonomous over the wide ranges of operating and topology conditions, the supporting computer platforms will have to, therefore, become hybrid and with sufficient flexibility to switch the communication protocols of external interfaces [10], [11]. Given the complexity of very large interconnection grids, and vastly diverse time rates at which communication protocols need to learn about the system conditions and adjust accordingly, this is only possible using a highly parallelized actor-oriented design.…”

Application of ATM-based network for an integrated distribution SCADA-GIS system

“…Functions including map production, facility inventory, distribution system design and maintenance service are supported by this system. On the other hand, functions of supervisory control and data acquisition (SCADA) system can assist operators in report monitoring and control of the electrical network [1]- [3]. With an increasingly complicated power system, the integration of these two systems with the anticipation of a better supervisory control has become crucially important.…”
