逆变器具有灵活、高效的特点，是新能源并网的主要接口。当多个逆变器连接到电网的同一个公共连接点时，逆变器非理想的电源特性，使得逆变器之间、逆变器与电网之间存在的谐波交互作用可能引发谐振， 使系统出现过电压、 过电流现象影响电网的电能质量，甚至威胁系统的安全稳定运行(Inverter is flexible and efficient, and it is the main interface of new energy integration. When multiple inverters are connected to the same common connection point of the power grid, the inverter is not ideal. The harmonic interaction between the inverters, the inverter and the grid may cause resonance, which causes the overvoltage and overcurrent to affect the power quality of the power grid and even threatens the safety of the system. stable operation)
