电力系统中旋转动能的减少对系统频率特性具有显著的不利影响。为了确保系统安全，必须系统地解决这个问题。鉴于此，我们考虑三个不同的指标，即i）同步发电机的最小功率穿透，ii）同步发电机的最小额定功率，和iii）最小同步动能，作为市场调度模型中的频率控制约束，并评估这些指标的系统的频率行为。结果表明，每个指标有不同的影响市场调度，并相应地，对系统的频率行为。结果表明，在换流发电普及率较高的情况下，为保证电力系统频率稳定，需要在市场调度模型中考虑最小动能需求作为频率控制安全约束。
The reduced amount of rotational kinetic energy in power systems has significant detrimental impacts on system frequency behaviour. To ensure system security, this issue must be addressed in a systematic way. Given this, we consider three different metrics, namely i) minimum power penetration from synchronous generators, ii) minimum rated power of synchronous generators, and iii) minimum synchronous kinetic energy, as frequency control constraints in the market dispatch model, and assess frequency behaviour of the system for these metrics. The results show that each metric has a different impact on market dispatch, and, accordingly, on the system frequency behaviour. It is shown that with high penetration of converter-based generation, we need to consider a minimum kinetic energy requirement as a frequency control security constraint in the market dispatch model to guarantee the frequency stability of power systems.
