Model Prediction Based Energy Optimization Strategy for DC Microgrid Groups Considering Network Loss
The DC microgrid group realizes the interconnection and energy mutual support of multiple DC microgrids
and improves the power supply efficiency and reliability of a single DC microgrid. However
the access of multiple DC subnets makes the topologies of DC microgrids more complicated and increases the network transmission loss and difficulty in coordination control. This paper proposes an optimization strategy with the minimum loss as the goal and an adaptive distribution coefficient. Through the correction of the predicted power of each subnet
the coordination and optimization of the power of the DC microgrid group can be realized. In order to predict the power changes of each subnet
this paper proposes model predictive control based on the pulse width modulation (PWM)
which reduces the amount of online calculations. Finally
the effectiveness of the proposed method is verified by simulation and experiment.
