Wind-DFIG wireless controlled using EGPRS standard applied to the ancillary services in a smart grid environment

摘要

This paper presents an alternative topology analysis for reactive power control in wind farms with wireless communication link integration. The co-simulation environment with telecommunication, machine control, and power system demonstrate in this analysis, that it can be an useful solution for planning the operation of modern power systems and their ancillary services in a smart grid scenario. A low cost and easy implementation EGPRS standard wireless link was adopted to perform the communication from the smart grid operator and the wind farm with the objective of maintain the voltage levels under established limits. The wireless communication was used to send the value of measured voltage of one critical bar to the operator and to return the reactive power reference to the wind farm. The studied scenario is represented by a seven bar power system model connected to a DFIG wind farm. The results obtained by this co-simulation endorse this original proposal and show its operability.
