Communication Improvements for Intelligent Systems in Microgrids - Part I

Microgrids are small-scale electric power systems that emerge as an alternative to solve the current problems of conventional networks and transportation. The main objectives that they pursue are the reliability, diversification of energy resources, reduction of carbon emissions, reduction of costs and the introduction of intelligent control techniques, which increase dependence on communication networks. Some research related to communications in electrical networks and transportation has been developed, but few are related to the appropriate communication system, according to the intelligent control algorithm. This paper proposes the best architecture for intelligent microgrid applications based on latency, QoS, bandwidth and capital cost, to improve control and operation. In addition, the fundamentals of communications and control strategies for intelligent micro-grids and electric vehicles are described. The results show that communication technology affects the performance of control applications and the smartness of the grid, which causes poor quality of service.
