    Autonomous microgrid based parallel inverters using droop controller for improved power sharing
    (Institute of Advanced Engineering and Science info@iaesjournal.com, 2020) Siddaraj, U.; Yaragatti, U.R.; Nagendrappa, H.; Jhunjhunwala, V.K.
    The existing microgrid has become a challenge to the sustainable energy source to provide a better quality of power to the consumer. To build a reliable and efficient microgrid, designing a droop controller for the microgrid is of utmost importance. In this paper, multiple voltage source inverters connected in parallel using an active power-frequency/reactive power-voltage droop scheme. The proposed method connected to two distributed generators local controllers, where each unit consists of a droop controller with an inner voltage-current controller and a virtual droop controller. By adding this controller to the microgrid reliability and load adaptability of an islanded system can be improved. This concept applied without any real-time communication to the microgrid. Thus, simulated using MATLAB/Simulink, the obtained results prove the effectiveness of the autonomous operation's microgrid model. © 2020, Institute of Advanced Engineering and Science.

    Autonomous Microgrid Using New Perspective on Droop Control in AC Microgrid
    (Springer Science and Business Media Deutschland GmbH, 2024) Siddaraj, U.; Yaragatti, U.R.; Nagendrappa, H.
    Providing higher quality power to consumers through the existent microgrid is now a problem for the renewable energy source. Designing a droop controller for the microgrid is a necessity to construct a dependable and effective microgrid. In this paper, a P–F/Q–V droop method is used to connect several VSIs in parallel. Their parallels and differences are amply discussed in this study. A frequency droop control method and a virtual impedance approach are combined in the suggested method, which is coupled to two distributed generation (DG) local controllers and has each unit having a droop control and a voltage-current controller. An islanded system's load flexibility and microgrid reliability can both be enhanced by adding this controller. The microgrid was subjected to this idea without any real-time communication. Simulink/MATLAB was used to simulate this. The results obtained show that the microgrid (MG) model is effective in autonomous operation. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd 2024.
