Abstract

Stability, voltage and frequency control in the shipboard microgrid is one of the important topics in preventing the breakdown of facilities and equipment, as well as the safety of the shipboard operators, which can be discussed in the topic of advanced defense. In this paper, an independent automatic control method for sharing reactive power among energy sources, as well as frequency stabilization in order to improve stability and voltage and frequency control in shipboard microgrids, is presented using the decentralized droop control method. In this article, in order to evaluate the correctness of the results and the performance of the control system, two criteria are considered. The first one is the angular frequency index, which is used to check the performance of the system in stabilizing the frequency in different modes of operation. The second one is the voltage indicator, which is 237V in normal operation mode, and the voltage difference with this value indicates the error of the control system, which is mentioned in the simulations. The simulation results are presented for different scenarios and it is shown that in all conditions, even in the case of sudden load change, the control system operate appropriately and with the sharing of reactive power and the proper operating of the frequency stabilizer, the voltage is within the allowed range. In addition, the frequency has also returned to its initial value.
