Economic analysis of a controllable device with smart grid features applied to LED street lighting system

摘要

Almost all luminaires that are used in street lighting system does not have communication, control and management infrastructure. Moreover, the artificial lighting system is responsible for the consumption of approximately 30% of all electricity generated in the world. Within this context, the LED technology offers flexibility and high efficiency, being suitable to be connected with smart devices, allowing the usage of possible alternatives to reduce energy consumption and providing significant economic saving. This work aims to perform an economic analysis of a controllable device with smart grid features applied to LED street lighting system in order to evaluate the efficiency of its usage as well as possible benefits on public lighting system and monitoring of low voltage grid parameters. The results have shown low payback periods and a promising internal return rate when compared with other applications, such as saving accounts. The smart grid features on the controller allows simple integration with renewable sources and central management and controlling lighting system.
