For energy storage, application research of hybrid energy storage system (HESS) in microgrid is extensive. For example, Ref [16], a multi-source PV/WT energy system scale optimization method was designed based on HESS, which took charge and discharge
The U.S. Department of Energy (DOE) defines a microgrid as "A group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. A microgrid can connect and disconnect from the grid to enable it to operate in both grid and island
A different EMS, based on a stand-alone power system that takes into account the utilization cost of the energy storage system, was introduced by Torreglosa et al. [13]. The comparative study carried out by Castañeda et al. [14] highlighted that the EMS based on the minimization of utilization costs leads to a higher utilization of the hydrogen
In [13], particle swarm optimization was used to optimize the objective function for energy management of a solar energy system with energy storage by considering the energy price of the main grid. In [14], a proposed energy management system (EMS) uses only three rates (low, medium and high) for the grid tariffs and a
The electricity price obtained from the optimized microgrid system is 0.18 SAR/kWh, which is quite low in comparison to generation through a base system (0.38 SAR/kWh) and a diesel generator
The total cost, which includes the cost of generation units, exchanged electricity cost, and BESS investment cost, is considered as the fitness function for the problem.
The main goal to design hybrid wind–solar generating systems with hydrogen energy storage is reliable supply of the load, under varying weather conditions, with minimum cost. In this paper, a hybrid WG/PV/FC generating system was designed for a 20-year period of operation.
Microgrids (MGs) are playing a fundamental role in the transition of energy systems towards a low carbon future due to the advantages of a highly efficient network architecture for flexible integration of various DC/AC loads, distributed renewable energy sources, and energy storage systems, as well as a more resilient and economical on/off-grid

Battery energy storage is rapidly securing a central place in the future of the power grid. The incumbent grid—a system built to provide a one-way flow of power from centralized, predominately fossil-fueled power stations to distant customers—is giving way to a rapidly emerging new system. Scalable and increasingly cost-competitive
