Editing Power-flow study (section)

==DC power flow==
DC power flow (also known as direct current load flow) gives estimations of lines power flows on AC power systems. Despite the name, DC power flow is not an analysis on [[direct current]], but rather on alternating current. DC power flow looks only at [[active power]] flows and neglects [[reactive power]] flows. This method is non-iterative and absolutely convergent but less accurate than AC Load Flow solutions. DC power flow is used wherever repetitive and fast load flow estimations are required.<ref>[https://link.springer.com/content/pdf/bbm%3A978-3-642-17989-1%2F1.pdf Seifi, H. &. (2011).
