A Distributed Energy Management System Based on Open Architecture Rules

The advent of Open System and Distributed Computing technologies into the Energy Management System (EMS) environment promises a multitude of benefits to tile Electric Utility. These benefits overcome the inherent and unavoidable limitations of EMS systems based on the proprietary technologies of the previous decade.The Open System attributes that are expected to be available are:Interoperability refers to the abllity of computers from different vendors to exchange information. Interoperability will allow electric utilities to leverage information that typically exist in various segments of the organization. This will help optimize operation and avoid the inefficiencies that is due to islands of information.Portability refers to the ability to use software on a variety of computer systems made by different vendors. Products from EMS vendors have, by necessity, been based on proprietary technology. The past decade, however, has witnessed such explosion of coniputer technology that equipment become obsolete in a matter of months. It is imperative, therefore, that products from EMS vendors embrace open system teclinology to protect the investmenls of the electric utility.Distributed Computing, in coiicert with Open Systems technology, is expected to overcome problems of Installed, proprietary EMS control centers not able to expand and extend beyond the initially delivered configuration. The hope Is to provide a continuous evolution of installed systems. This avoids the costly strategy of investing in suBicient spare capacity a t the tiiiie of purchase due to the lack of field expandabiiity and evolvability after installation.The use, however, of the advanced techrrologies evolving Troni the computer industry poses a higlily complex cliallerige to tlie designers of real t h e energy control systems. The challenge is how to achieve the advantages mentioned above and still maintain sufficient architectural simplicity to achieve a higly reliable and responsive real time system. l h e critical component in sucli an operational framework is the distribution and maintenance of tlie database. The elegant simplicity of a centralized database system has to be abandoned to gain the benefits promised by a .distributed architecture.
