An Extended DC Power Flow Model Considering Voltage Magnitude

Dundun Liu / Lu Liu / Haozhong Cheng / Shenxi Zhang / Jieqing Xin

A quasi-linear relationship between voltage angles and voltage magnitudes in power flow calculation is presented. An accurate estimation of voltage magnitudes can be provided by the quasi-linear relationship when voltage angles are derived by classical DC power flow. Based on the quasi-linear relationship, a novel extended DC power flow (EDCPF) model is proposed considering voltage magnitudes. It is simple, reliable and accurate for both distribution network and transmission network in normal system operation states. The accuracy of ED-CPF model is verified through a series of standard test systems.
