Design and Analysis of Seaport Microgrid with Ship Loads

The necessity for renewable energy and efficiency has increased due to the increase in energy demand and limited resources. Increasing energy demand in seaports makes microgrid design essential for sustainable development. The design of micro grids is crucial to achieving energy interconnection, optimizing energy utilization, and enhancing grid resili-ence. These technologies improve power system flexibility and optimize seaport operations. Ship loads demonstrate significant volatility and uncertainty. This volatility necessitates a power system capable of flexible response. The design of the seaport micro grid should take into account the characteristics of ship loads to achieve efficient energy management. Fluctuations in ship loads impact the stability of the power system. Ship loads are classified into constant, variable, dynamic, and pulse loads. A seaport microgrid system for ship loads has been built in MATLAB-Simulink to analyze voltage stability. The fluctuation of the 10 kV AC bus voltage for the impact of ship loads, the uncertainty of power generation, and symmetrical faults (LLLG) have been analyzed. The distribution static synchronous com-pensator (DSTATCOM) has been incorporated into the grid to improve voltage stability, and its role has been analyzed.
