Adaptive control access of stand-alone power systems

The recent liberalization of the electricity market in Romania and the growing interest for using alternative sources of energy are the premises favorable for this proposal. The main objective of the article is to stimulate interest of the consumers for the green energy considering the environmental and the financial impact of this one. For these arguments, this article proposes a real application, with autonomy in the power supply, for control access to parking of vehicles, for lighting the car park and for its management in terms of occupancy rates. The main characteristic of this application is its functioning with energy from alternative sources (sun and wind).
