An Automatic Transfer Switch (ATS) System Based on Cost Effectiveness - Lebanese Case Study

Lebanon's electrical power sector faces critical challenges, including frequent power outages, reliance on imported fuels, rising energy costs, and environmental concerns. To address these issues and reduce dependence on fossil fuels, integrating renewable energy, particularly solar power, is essential. Solar energy is a prevalent and viable option in Lebanon, offering a pathway to greater energy independence and sustainability. A practical solution involves designing a system that manages electricity flow between solar and conventional sources using an Automatic Transfer Switch (ATS). This system will not rely solely on fixed conventional priorities but will dynamically select power sources based on availability, load demand, and the cost of energy from each source. This approach ensures a reliable power supply by optimizing the use of solar energy, grid power, private generators, and batteries. Moreover, the ongoing economic downturn in Lebanon has made cost-effective energy management a priority. To help consumers control their spending, the project will incorporate a user budget limitation scheme using electric meter system. This system will provide detailed insights into energy consumption, enabling efficient energy use and cost management. The control between different energy sources and the integration of the budget limitation scheme is done using an Arduino microprocessor. Thus, the project will enhance energy efficiency, ensure a reliable power supply, and contribute to a more sustainable and resilient electrical power system in Lebanese residential areas.
