ABSTRACT This paper presents a proof of concept of a reconfigurable non-isolated DC-DC converter for connecting different energy sources and loads in a DC microgrid. In this chapter, the. . This can be overcome by adding a boost converter with the MPPT control algorithm, which maintains the required DC voltage level for the AC grid inverter. Such a solution is preferred because of the continuous character of the input current. The single-phase source is coupled to a single-phase PFC boost converter, which enhances the input PF utilizing two feedback loops: outer voltage loop control and inner current loop. . This work was supported in part by the Estonian Centre of Excellence in Foundations of the Universe under Grant TK202 funded by the Estonian Ministry of Education and Research, and in part by the research was conducted using the research infrastructure “European Organisation for Nuclear Research”. . In order to reduce the economic costs, enhance the efficiency, and improve the structural stability of microgrids, this paper proposes a novel AC/DC hybrid microgrid structure.

The research in this paper is divided into the following steps: (1) constructing a multi-microgrid model primarily based on renewable energy; (2) formulating an optimization model with the objective of minimizing economic costs while ensuring stable system operation and solving it; (3). . The research in this paper is divided into the following steps: (1) constructing a multi-microgrid model primarily based on renewable energy; (2) formulating an optimization model with the objective of minimizing economic costs while ensuring stable system operation and solving it; (3). . These factors motivate the need for integrated models and tools for microgrid planning, design, and operations at higher and higher levels of complexity. This complexity ranges from the inclusion of grid forming inverters, to integration with interdependent systems like thermal, natural gas. . Due to the dominance of renewable energy sources and DC loads, modern power distribution systems are undergoing a transformative shift toward DC microgrids. The stochastic optimization and robust optimization techniques are utilized to deal with the long-term uncertainty of energy. . To address this, this paper proposes an operational scheduling strategy based on an improved differential evolution algorithm, aiming to incorporate power interactions between microgrids, demand-side responses, and the uncertainties of renewable energy, thus enhancing the operational reliability. .

Thus, the bidirectional DC-DC converter interface connecting DESs to the microgrid has two main objectives: (1) to control the direction and amount of power to and from the storage device and (2) to control the DC link. . es in various applications including microgrids. The DC-DC converter control is designed to control the DC bus voltage and the battery. . This work presents a multifunction converter structure that integrates a two-way power conversion method in grid-connected or independent DC/DC/AC/DC for microgrids. During grid-connected mode, these storage units are charged from various DG sources as well as the main grid.
