On this basis, an energy coordination control strategy based on the power difference is designed, which can coordinate the working state of PV power generation units according to the power condition of the system. The integrated DC microgrid has been simulated under different conditions in MATLAB/Simulink.
For the integrated DC microgrid, the designed energy coordination control strategy should meet the following conditions: Ensure the power supply of the EV charging unit. Ensure the charging and discharging power of the energy storage device is below the limit. Maximize the use of PV energy as much as possible.
Energy storage unit control strategy The energy storage unit is essential to maintain the stable operation in the standalone mode of the integrated DC microgrid. When the system power changes, the bus voltage will also change.
The energy storage unit regulates the system power balance in the integrated DC microgrid. When the output power of the PV generation unit is larger than the absorbed power of the load, the energy storage unit absorbs the energy in the system by charging; conversely, the energy storage unit provides energy to the system by discharging.
The simulation results show that the proposed coordination control strategy can not only effectively improve the stability of the DC microgrid system but also reduce the capacity redundancy of the energy storage device. 1. Introduction
The above simulation results verify that the coordinated control can limit the charging and discharging power of the battery within the acceptable range compared with the conventional control strategy to ensure more accurate DC bus voltage recovery, which illustrates the effectiveness of the designed control strategy. 6.
