Abstract

The intermittent nature of energy has increased the tendency to use hybrid systems, and the optimal control of these systems in terms of cost and reliability has become very important with an increase in the use of hybrid renewable energy systems, especially in remote electrification. In this research, energy management has been done using dynamic decision-making algorithm and intelligent controller. The system automatically and dynamically adapts to changes in the output of the solar and wind power sources and batteries and is able to respond to external requests such as voltage signals, power system limitations, or operator’s requests. The results have showed that if the fraction of renewable energy is 23.8% with an average annual fossil fuel consumption of 407 liters, the production energy of the combined renewable energy conversion system will be equal to 1697 kWh/yr. Accordingly, the net present value will be equal to 553.68 US dollars, and the domestic return rate will equal 21.49% with a return period of 15.71 years.
