Photovoltaic (PV) and other renewable energy is direct current (DC), with the increase of DC load, they are connected to a certain voltage level of the DC power grid is a better solution, because it allows alternating current (AC)–DC converters to be reduced in use to improve efficiency and reduce costs [1– 3]; usually, the power generated by
Abstract: The multi-directional flow of energy in a multi-microgrid (MMG) system and different dispatching needs of multiple energy sources in time and location hinder the optimal operation coordination between microgrids. We propose an approach to centrally train all the agents to achieve coordinated control through an individual attention mechanism with a deep
A city located on the west coast of Sweden was utilized as the case study. Indeed, the simulation results indicated that the 70:30 shares of wind-PV in electricity provided the maximum performance in load matching for the V2G scheme. This means an increase in load matching from 68 % for opportunistic charging to 73 % for smart charging and 84 % for V2G.

Initially we observe and record the load patterns and solar and wind power generated
The objective of this paper is to describe the development of a multi-agent system for the control of a PV-based microgrid. A case study is presented to demonstrate the agents'' abilities to island the PV-based microgrid in the event of an external fault, secure critical loads, and resynchronize the microgrid to the main grid after the fault is cleared.

In the distributed optimization of micro-grid, we consider grid connected solar micro-grid system which contains a local consumer, a solar photovoltaic system and a battery. The consumer as an agent continuously interacts with the environment and learns to take optimal actions. Each agent uses a model-free reinforcement learning algorithm
It is possible to develop an advanced adaptive protection system that enhances the coordination of the protective devices in microgrids by combining the IEC 61850 utility automation protocols with the server technology running at the substation central controller. This is a practical example of Microgrid operation .
The microgrid can determine when it is most beneficial to use its own generating capacity or when to buy electricity from the main grid . The operating costs for the microgrid can for example be reduced by importing electricity during low price periods.
In Simris, Arholma, and Hailuoto island microgrid projects used overcurrent with communication line protection for the three-phase fault and residual voltage protection for the earth fault protection. The Fault analysis of the Simris model in this work suggests the conclusion as explained below.
A microgrid has different protection strategies based on its mode of operation since power can flow in both directions and the fault current level can differ depending on the mode of operation. If a fault occurs it is necessary to disconnect only the faulty part to maintain system reliability.
In other words, the RES are utilized to the maximum together with the loads and battery. By analyzing the capacities in island mode, an under dimen- sioned system can be avoided. A LOLP of 10% means that the microgrid can be self-sufficientfor90%ofthetimeincaseofrandomoutageevent. InAppendixA.1 TableA.4,thecalculationisfurtherdescribed.
This is a practical example of Microgrid operation . The Microgrid network is part of Himmerlands Elforsyning (HEF) in Aalborg, Denmark. This project contains a combined heat and power (CHP) plant with three 3.3MW gas turbine generators and three 630 kW Wind Turbine Generators as shown in figure 8.
