The public lighting system was being a vital part all over the world for many years. Indeed, as the number of population and urbanism grow, this system is becoming a primordial part of our life comfort. Therefore, it is used extensively leading to an increased important amount of electrical energy being consumed. This paper proposes an idea of an intelligent energy management system (EMS) for public lightening system consumption based on an autonomous hybrid sources of electrical energy. It is composed of a PV system installed at the top of the lightening system and a battery storage system, where an intelligent energy management system is used to ensure the charging of the battery during the daylight with the option of supporting the PV system production in case of low period irradiation during the day. Whereas, during the night, the battery fully powers the lightening system. In the same for the protection of the battery system and its related lifespan, the proposed (EMS) takes into accounts this issue. Furthermore, this system has the ability of recognizing accurately the basic data on the length of the day, the sunrise time and sunset time automatically based on the location of the used public lightening system which is defined by its longitude and latitude. The proposed EMS is built around a special electronics card including display screen of main information with the insertion of special sensors such as current and voltage sensors, which were built by the authors. The proposed system has been tested in a known location where the obtained results prove the validity of the proposed management system for ensuring the operation of the public lightening system.
