Arquitetura orientada a serviços aplicada ao desenvolvimento de um controlador de recursos distribuídos de energia fotovoltaica compatível com o padrão IEC 61850

Abstract

The ever-growing demand for energy, the losses related to transmission and distribution, and the environmental impact of traditional energy sources have made the Renewable Distributed Generations (RDGs) a suitable option for power grid expansion. However, additional problems arise with the increase of RDGs connected to the grid, such as voltage rise, harmonic current emissions, and false islanding. The overcome of such obstacles involve the control of a large number of Distributed Energy Resources (DERs), which additionally provides an opportunity to increase the power quality and reliability of the grid. The combination of hardware and software directed to perform such functionality is called Distributed Energy Resource Management System (DERMS). This work applies the concepts of Service Oriented Architecture (SOA) to develop the communication systems of a DERMS with emphasis on photovoltaic energy resources. The implemented system was able to monitor more than four hundred devices without significant delays in the polling period, and the average latency for communications with the utility was below 2ms, even with the use of encryption and the TLS protocol.
