Evaluation of a Generic Virtual Power Plant framework using service oriented architecture

The purpose of this paper is to find and describe a suitable software framework that can be used to help implement the concept of a generic virtual power plant in the future power system. The generic virtual power plant concept, along with the utilization of distributed energy resources, has many interesting properties that can influence the future shape of power markets. The concept holds many promises including cheaper power to the consumer, a more flexible and responsive power production and the support of a more environment- friendly development. In order to realize a software solution supporting the generic virtual power plant, an array of different software design principles, patterns and architectures must be applied. Especially Service Oriented Architecture (SOA) can aid in implementing the generic virtual power plant. An analysis of the Nordic power market has been carried out in order to identify potential issues and barriers, henceforth mentioned as challenges, connected with the introduction of the generic virtual power plant concept. In this paper, three use case scenarios will show how each of these challenges can be overcome by the proposed solution framework. The use case scenarios will be tested by a prototype that has been developed as proof of concept.
