Abstract. A microgrid (MG) is a stand-alone or grid-connected hybrid renewable system that uses distributed renewable and nonrenewable energy sources and energy storage systems (ESSs) to supply power to local loads. The system is ordinarily based on power electronics, with interface converters allowing the sources to supply
Since renewable energy resource is universally accepted as a promising method to solve the global energy problem, optimal planning and utilization of various distributed generators (DG) and energy storage (ES) devices deserve special concern. ES devices possess various characteristics in power density, energy density, response

A Micro Grid (MG) is an electrical energy system that brings together dispersed renewable resources as well as demands that may operate simultaneously with others or autonomously of the main electricity grid. The substation idea incorporates sustainable power generating as well as storage solutions had also lately sparked great attention, owing to rising need
Most of the micro-generators and energy storage devices are not suitable for supplying power directly to the grid and must be interfaced by PE devices. As stated previously, using PE interfaces leads to several challenges in the protection of microgrids, particularly in the islanded mode.
generator''s primary energy source is limited or extremely variable, such as in the case of power generation systems based on renewable resources. Thus, it becomes necessary to make the most of the energy resource available in the area where an MG is located, which could help to maximize the hours of energy supply (for islanded MGs) and lower

Nevertheless, energy storage devices are required to guarantee energy sus-tainability because renewable energy resources are sporadic and dependent on weather [13]. To regulate the power flow between sources, loads, energy storage systems, and the main Microgrids must have efficient energy management in place to
Microgrids can include distributed energy resources such as generators, storage devices, and controllable loads. Microgrids generally must also include a control strategy to maintain, on an instantaneous basis, real and reactive power balance when the system is islanded and, over a longer time, to determine how to dispatch the resources.
DERs are different sources that provide energy to the microgrid. Storage devices act as the backup support for the microgrids. Power electronics converters are required for the conversion of power and for the interlinking of DC/AC grids and other microgrids [10]. 4.4.1. Modeling of battery energy storage system
Several multidisciplinary studies cover the wide variety of distributed energy resources that can be deployed in microgrids [24], [25], [26], [27].Some examples of the options available for generation and storage today, including their advantages and disadvantages, are provided in Table 1, below general, microgrids are somewhat

A 2018 World Energy Council report showed that energy storage capacity doubled between 2017 and 2018, reaching 8 GWh. The cur-rent projection is that there will be 230 GW of energy storage plants installed by 2030 [2–5]. Microgrids are a means of deploying a decentralized and decarbonized grid.
Microgrids require a sophisticated energy management system to ensure that energy is being used efficiently and effectively, and that the flow of energy is balanced between generation and storage. In addition, microgrids must be designed to be flexible and scalable, able to adapt to changing energy needs and requirements.

The operator of the Multi-Energy Microgrid (MEM) aims to minimize the total operational cost by optimizing various components, including the Combined Heat and Power (CHP) system, boiler, electric vehicles (EVs), and multiple energy storage systems. This optimization is done to meet local electrical, gas, and thermal demands.
1.1 Background. Generally, a microgrid can be defined as a local energy district that incorporates electricity, heat/cooling power, and other energy forms, and can work in connection with the traditional wide area synchronous grid (macrogrid) or "isolated mode" [].The flexible operation pattern makes the microgrid become an effective and
