This article presents an optimized approach to battery sizing and economic dispatch in wind-powered microgrids. The primary focus is on integrating battery depth of discharge (DoD) constraints to prolong battery life and ensure cost-effective energy storage management. The model is developed to minimize the operational costs of the microgrid,taking into account the nonconvex degradation cost function of the battery energy storage system. The optimization is simulated for 8-days time horizon. Sustainable floating residentials, a microgrid project in Ams-terdam, is used. . Abstract—This study investigates the economic dispatch and optimal power flow (OPF) for microgrids, focusing on two config-urations: a single-bus islanded microgrid and a three-bus grid-tied microgrid.

Therefore, this study presents a composite controller incorporating a global integral terminal sliding mode controller with a backstepping controller. . Fluctuations in distributed power supply and sudden changes in DC load power will lead to serious DC bus voltage fluctuations in DC microgrids, which will have a certain impact on the safe and stable operation of DC microgrids. The system inertia is enhanced by exploring the auxiliary power of DESS and thus t e stability of the voltage is improved. In addition, the microgrids suffer from an inherent low-inertia problem.
