Load Flow with AC-DC <strong>System</strong>s<br />
• Unified method<br />
- solution vector is extended with the dc<br />
variables<br />
- complex to program and hard to combine<br />
with developments in ac power flow solution<br />
techniques such as fast decoupled method<br />
• Sequential method<br />
- ac and dc equations are solved separately<br />
in each iteration<br />
- easy to implement, but convergence<br />
problems are there
