Abstract

Abstract For future power systems, microgrids are one of the most significant considerations. In order to meet future energy demands, mitigate climate change and support sustained growth, renewable energy sources emerged. This paper is focused on two resources as Solar and Wind energy. The voltage and frequency of the line side converter are controlled with indirect vector control with droop characteristics. The setting of frequencies varies according to the battery energy level, which slows down when the battery is charged or discharged. The system can also work if the wind power source is not available. The maximum power point tracking in their control algorithm, both wind and solar energy blocks. This device is designed to function entirely automatically, taking all practical conditions into consideration. The device also has an external battery charging power supply without any extra requirements. A MATLAB/SIMULINK model is developed for various conditions e.g. variability and irregular characteristics of the wind speed, solar radiation level and unbalanced loads.
