Modeling a Microgrid that Integrates Renewable Energies in IEC 61850-7-420 and IEC 61400-25-3.

This paper explores a information model for a small electrical network (Microgid) that integrates renewable energies based in standard protocols. The information model of the micro network will be made up of a solar energy source, a wind energy source, an energy storage element, a non-renewable source such as a diesel generator. Each of the renewable sources is modelling based on the logical nodes of the IEC 61850-4-2, IEC 61850-7-420, IEC 61400-25-2 standards. The objective of this definition is select: logical nodes, variables and commands, required to achieve coordinated control. This interchange of information is required to develop more complex algorithm of distributed control resources. A control architecture based and structured in these standards will to allow interoperability between the controllers of the power sources of the network, regardless of who develops and manufactures the device. This work is intended to ensure that information can be exchanged to control the load flows in the electric network that integrates renewable energies. All communications between controllers will be based on these protocols that allow the exchange of information over ethernet networks for critical process. [ABSTRACT FROM AUTHOR]
