摘要

电力系统可用输电能力(ATC)定义了不同区域间的功率交换能力

ATC信息对于电力市场参与者而言至关重要。然而

随着以天然气为一次能源的燃气轮机(NGFPP)发电比重的显著提升

传统ATC计算并没有考虑NGFPP的一次能源供应以及天然气系统的运行约束

显然并不恰当。为此

文中研究了计及电-气互联能源系统静态安全约束的电力系统ATC计算

提出了电-气互联能源系统静态安全域的概念。采用基于线性预测的连续潮流法求解

以线性预测法辨识制约ATC的关键约束

不仅实现了ATC的快速、准确计算

而且为天然气系统运行状态的调整提供了参考。最后

算例分析验证了文中所述方法的适用性。

Abstract

Power system available transfer capability (ATC) defines the power exchange ability among different areas. The ATC information is crucial to power system market players. However

with the dramatic growth of natural gas fired power plant (NGFPP) proportion

the adequacy of primary energy and the natural gas system operational limits have not been well considered in the conventional ATC calculation

which is obviously inappropriate. In response

power system ATC calculation considering electricity and natural gas coupled energy system steady-state security constraints is primitively studied. Meanwhile

the concept of steady-state security regions of electricity and natural gas coupled energy systems is presented. Furthermore

continuation power flow based on the linear prediction method is implemented. The linear prediction method is used to identify the critical constraint

which benefits both the fast and accurate ATC calculation

and the adjustment of natural gas system operating states. Finally

applicability of the proposed method is verified by test results. This work is supported by National Natural Science Foundation of China (No. 51277052
