To meet the supply–demand balance of the system and to achieve economic efficiency, energy is shared among the three MGs through internal coordination. Figure 9. The electricity power sharing between interconnected microgrids. Figure 10. The thermal power sharing between interconnected microgrids.
A microgrid is a group of interconnected loads and distributed energy resources that acts as a single controllable entity with respect to the grid. It can connect and disconnect from the grid to operate in grid-connected or island mode. Microgrids can improve customer reliability and resilience to grid disturbances.
The comparative area of RES and load of interconnected microgrids system before and after the load scheduling is shown in Figure 5. From this figure, it can be seen that after load scheduling, the interconnected microgrids system can consume a portion of RES to the maximum extent and improve the utilization of renewable energy.

However, the uncertainty of renewable energy and the coupling of multiple energy sources makes energy management difficult in connected microgrids.
In, a green power value-driven energy sharing approach for interconnected microgrids is proposed. In, the interactions between interconnected microgrids are investigated and the incentive mechanisms are developed by using Nash bargaining theory to encourage energy trading and sharing.
Method 1: No electric load scheduling of demand side and electricity–thermal energy sharing among microgrids. Method 2: Electric load scheduling of demand side and no electricity–thermal energy sharing among microgrids. Method 3: Electricity–thermal energy sharing without considering electric load scheduling of demand side among microgrids.
