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

Abstract

Abstract-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.

The Energy-Efficient Control Solutions of Smart Street Lighting Systems: A Review, Issues, and Recommendations

“…Additionally, LED outperformed HPS in the test. In terms of payback time, LED luminaries presented a DPP (discounted payback period) of 3.5 years and an internal rate of return (IRR) of 30% for a 10 to 12-monthvintage scheme, indicating the LED's unique number one value as a barrier [56]. The on-grid PV LED system succeeded in meeting all the requirements, and its payback time was determined to be 20.54 years [57].…”

Smart Street Light Control: A Review on Methods, Innovations, and Extended Applications

“…Another approach set predefined light levels for specific times throughout the night, using motion sensors to trigger full brightness when necessary, ensuring a blend of static and adaptive control for enhanced safety [74]. Economic analysis demonstrated low payback periods and a promising internal return rate [75]. However, in terms of energy consumption, some cases exceeded the static control scheme due to maintaining high light levels, especially in busy roads [76].…”

Revision of Smart Street Lighting LED

“…High Intensity Discharge (HID) solutions [35]. In Table 1, the characteristics between different types of luminaires can be compared: luminarias are pertinent for this type of lighting [32], [36]. Something similar happens with the HID luminaire.…”

“…The case study to determine the final price was made in the City of Juiz de Fora, Brazil. [36] This city of Brazil was selected because it is a developing country and has shown an interest in the concept of Smart Cities in recent years [52]. It is important to note that it is not easy to determine the exact cost of an intelligent lighting system due to different circumstances, such as the change in the price of the components over time, import costs and taxes on the devices.…”
