本发明公开了种直流调频参与的区域控制性能评价方法，包括以下步骤：计算广义区域控制偏差GCE；计算单区域或多区域的广义控制性能评价参数GPS；计算单区域或多区域的整体控制性能评价参数DPS；两种参数协调评价。本发明适用于直流输电参与调频。在直流输电参与调频下，频率偏差会受到区域次调频、二次调频以及直流调频共同调节的作用。所以对直流调频参与的区域进行控制性能评价需要剥离出直流调频的责任影响，对区域自身责任进行控制性能评价。而本发明中的广义控制性能评价参数GPS和整体控制性能评价参数DPS，通过协调评价，从单区域到多区域的指标推导，适用于直流输电参与调频下的各调频责任的区分。 The invention discloses a DC frequency modulation participated area control performance evaluation method. The DC frequency modulation participated area control performance evaluation method comprises the following steps of calculating a generalized area control error GCE; calculating a generalized control performance evaluation parameter GPS of a single area or multiple areas; calculating an integral control performance evaluation parameter DPS of the single area or the multiple areas; and performing coordinated evaluation by using the two parameters. The DC frequency modulation participated area control performance evaluation method is applicable for DC transmission participated frequency modulation. In the presence of the
