Intelligent street light system in context of smart grid

Abstract: Energy utilization & management schemes at home, business and industry have been successfully implemented in the context of smart grid. But the public street light system has not been taken under serious consideration. The conventional street light system is the potential consumer of electricity, and large amount of electricity wasted. The consumption of energy is consistent and has no concern with the activity and frequency of traffic. With the advancement of technology, numerous solutions like LED, illumination controller/dimmer, Wireless and ICT based designs have been proposed. The main objective of this research is to evaluate these technologies and integrate with smart grid to efficiently consume the energy in the street light system. For this purpose, architecture of an intelligent street light system has been recommended. We also proposed an algorithm to conserve the energy according to the area and traffic. Results are computed through simulated experiment and compared with other solution.

Energy efficient smart street light

Abstract: India is one of the developing countries facing difficulties with shortage of power resources, availability of energy due to ever increasing population. Over dependency on fossil fuel can cause problems that affect the next generation to survive. In the current context, it is very important to know how to minimize the energy consumption and how to adapt various energy efficient techniques at least for power limited systems to overcome the energy crisis. Many research works are carried out and people are looking for a clean and better solution for the next generations. The new era Internet of Things has given a new dimension leads to an energy efficient management system. Internet of Things can overcome the existing energy wastage problems to a great extent. IoT is a combination of electronic devices like sensors and intelligent software applications to build an effective data exchange network. In this paper, it is proposed that smart street light design which is one of the basic ideas in reducing wastage of power as in the concept of building a flexible smart city management plan which is essential to the prosperous life of the future generations residing in city environments. To implement this scheme a low-cost Wi-Fi module ESP8266, Light-dependent sensor and ultrasonic sensor are used. Here the LDR sensor is used ON-OFF the street light based on the ambient intensity level. This switching can be done by ESP8266 after reading the LDR value. The need of Ultrasonic sensor comes into picture when a vehicle or a person comes in the range, the light glows with 100%brightness otherwise, the street light glows with less intensity (60%). This avoids unnecessary power waste during the night when there is no sign of vehicle or pedestrian. Thus by using these two sensors, an intelligent automatic light is designed with the help of IoT frame work which is energy efficient.

Lighting Brazilian cities : business models for energy efficient public street lighting

Abstract: Cities are among the world´s largest consumersof electric energy, accountable for two-thirdsof total electricity consumption and for over 70 percent of global greenhouse gases emissions. Publicstreet lighting systems contribute significantly toa city´s energy consumption. In Brazil, the cost of energy for public lighting already represents thesecond most expensive item of most municipalities’ budgets, surpassed only by payroll expenditures.Furthermore, new regulations require all themunicipalities to own the city’s public lightingassets, making public lighting one of the few sectors in which local authorities have direct control over energy-consuming assets (contrastedwith other high energy-consuming sectors such as transport). As a result, the local authorities willhave every incentive to invest in and implementlighting projects by themselves.In Brazil, the current public street lighting inventory primarily consists of mercury and HPS lamps, which over time will tend to be replaced by more efficient technologies such as Light-Emitting Diodes (LEDs). This new technology is already in operation in some major cities in other countries. The availability and increasing spread of LED technology offers a unique opportunity for Brazilian cities to reduce their energy consumption. This is especially important and beneficial to cities, considering the sharp increase in energy prices in recent years.In spite of the substantial benefits associated with the conversion of the installed public lighting network in Brazilian cities, major economic financial and institutional obstacles still need to be overcome.In order to reap the benefits of conversion to LED,it is necessary to design and implement business models that can enable the necessary investments.These business models must take into account the diversity of Brazil’s municipalities. Furthermore,consideration must be given to designing financial solutions that can raise private sector capital while mitigating municipal credit and project performance risks.
