variable-pitch grid

In order to analyze the influence on continuation power flow calculation by change of line resistance, this paper presents the electro-thermal power flow model and electro-thermal continuation power flow model in which the line resistance is considered as state variable of power grid.

为分析其对连续潮流计算产生的影响程度，本文提出将输电线路电阻作为潮流的状态变量，首先建立包含电阻参数的电热耦合潮流模型，并进一步提出电热耦合连续潮流模型。

With the development of power system, the phenomenon of voltage fluctuations and flicker in power grid has become more and more serious, because lots of high-power variable load and other nonlinear loads flood into the power grid.

随着电力系统的发展，许多大功率变动负荷和其它非线性负荷大量接入电网，导致电网中电压波动和闪变现象日趋严重。
