An Energy Management and Control Strategy for Microgrid Systems with DC Photovoltaics

With the continuous deepening of the utilization of new energy in the large power grid, DC photovoltaic and energy interdependence have become a new type of energy utilization method, and the energy management strategy of the entire system has become a current research hotspot. new type of energy utilization method, and the energy management strategy of the entire system has become a current research hotspot. Firstly, in order to address the issues of photovoltaic absorption and transformer overload, this paper proposes an energy management and control strategy for microgrid systems containing DC photovoltaics. systems containing DC photovoltaics, flexible interconnecting devices, AC loads, and substation transformers. A mathematical model for energy A mathematical model for energy management and control is established, and an energy management and control strategy is developed. Secondly, the power variation relationship between devices was analyzed in different application scenarios. devices was analyzed in different application scenarios; Finally, through simulation analysis, photovoltaic absorption and transformer overload control can be achieved; In addition, the power variation relationship between devices and transformer overload control can be achieved. Finally, through simulation analysis, photovoltaic absorption and transformer overload control can be achieved; In addition, the energy management strategy proposed in this article has been successfully applied in practical fields, thereby verifying the effectiveness of the model. In addition, the energy management strategy proposed in this article has been successfully applied in practical fields, thereby verifying the effectiveness of the model and control strategy proposed in this article.
