摘要
为推动智慧城市新能源系统的建设,本文将建立一种基于智能微电网的充电系统,给智慧出行提供新的思路。智能微电网充电系统运行于孤岛模式,由于不需要与大电网电气联系,因而可以灵活地建立在城市的各个角落。孤岛智能电网充电系统是否能良好运行取决于母线电压的稳定性及能量流动的平稳性。因此本文重点研究母线电压的控制和能量流动管理方法,针对孤岛运行的交直流微电网系统,通过控制策略,旨在当系统外部发生变化时,系统能够及时做出应对,保持母线电压稳定,也能让交流侧与直流侧之间的能量互通。本文建立了一个典型的交直流微电网模型,并利用Matlab仿真验证了控制策略的有效性和可行性。
In order to promote the construction of new energy system in smart city,this paper will build a charging system based on smart micro-grid to provide new ideas for smart travel.Smart micro-grid charging system operation and islanding mode can be flexibly established in every corner of the city because it does not need to be connected with the large grid.Whether the charging system of islanded smart grid can operate well depends on the stability of bus voltage and the stability of energy flow.Therefore,this paper focuses on bus voltage control and energy flow management methods.Aiming at the isolated AC/DC microgrid system,through control strategy,the system can respond in time when the external system changes,maintain bus voltage stability,and also enable the energy exchange between AC side and DC side.In this paper,a typical AC/DC microgrid model is established,and the effectiveness and feasibility of the control strategy are verified by Matlab simulation.
