Microgrid protection must be adaptive, changing its behavior based on the system's operational mode to accommodate variable fault current and flow direction. When operating grid-connected, the primary strategy is coordination with upstream utility protection schemes., due to faults or equipment outages). These. . If microgrids are to become ubiquitous, it will require advanced methods of control and protection ranging from low-level inverter controls that can respond to faults to high-level multi-microgrid coordination to operate and protect the system. A novel method is proposed, based on an improved Dual-Competitive Deep Q-Network (D3QN) algorithm, which is enhanced. . Microgrids (MGs) have emerged as a promising solution for providing reliable and sus-tainable electricity, particularly in underserved communities and remote areas. Integrating diverse renewable energy sources into the grid has further emphasized the need for effec-tive management and sophisticated. .

This paper presents a two-stage dispatch (TSD) model based on the day-ahead scheduling and the real-time scheduling to optimize dispatch of microgrids. The power loss cost of conversion devices is considered as one of the optimization objectives in order to reduce the total cost of microgrid. . Hybrid microgrids combining photovoltaic (PV), wind turbine (WT), diesel generator (DG), and battery energy storage systems (BESS) provide a practical pathway for delivering reliable and low-carbon energy to isolated regions. However, their optimal sizing and dispatch planning constitute a. . diction-dependent dispatch methods can face challenges when renewables and prices predictions are unreliabl in microgrid. The multi-objective optimization dispatch problem is formulated to simultaneously minimize the operating cost, pollutant emission level as well as the. .
