论文摘要
可以通过同步发电机（SGS）的转子摆动动力学对传统电力系统的瞬时稳定性的基本机制进行物理理解。影响瞬态稳定性的基本因素是SG之间的功率角度关系。将大量基于逆变器的世代（IBG）整合到电力系统中不可避免地会改变原始的功率角度关系，从而导致更复杂的瞬态稳定性机制。在这封信中，分析了IBG对电力系统瞬态稳定性的影响。结果表明，IBG的连接将原始的动力角关系更改为非曲线曲线，引入了转子摆动峰的限制，因此为瞬态稳定性带来了新的瓶颈。
The fundamental mechanism of transient stability of the conventional power system can be physically understood with the rotor swing dynamics of synchronous generators (SGs). The basic factor affecting the transient stability is the power-angle relationship among the SGs. The integration of a large number of inverter-based generations (IBGs) into the power system inevitably changes the original power-angle relationship, therefore leading to a more complicated transient stability mechanism. In this letter, the impact of IBG on the power system transient stability is analytically investigated. It is shown that the connection of IBG changes the original power-angle relationship into a nonsinusoidal curve, introduces a limit on the peak of the rotor swing, and therefore brings about a new bottleneck for the transient stability.
