Abstract


In the last few years, Libya has faced problems with electric power, the most important of which is the lack of maintenance of electrical stations, the failure to establish new stations, and the cutting of some electric tower wires that connect electricity to homes and institutions. To solve this problem, this paper focuses on helping establish a smart home in Libya powered by a hybrid system and the grid. This paper has dealt with two major steps: optimizing home appliance sizing and managing their control. The goal of this sizing is to determine the appropriate number of photovoltaic (PV) panels and batteries to be used while considering efficiency and costs. The PVsyst software is used to estimate the energy generated and consumed, the size of PV panels and batteries, and the best solar radiation angle annually. Secondly, the energy management system proposed in this paper has several main objectives: tracking the system through twelve modes, monitoring the connection between the home and the grid, supplying the home with electricity when the grid is interrupted by another source, controlling the battery charging, reducing the electricity tariff, achieving self-sufficiency in energy, and not relying solely on the government grid. This approach is applied to a real house in Zawiya City, Libya, and the practical results confirm the effectiveness of the proposed control strategy.
