Flat start power flow

WebIn Section 2, a 3-layer BFS algorithm is proposed to solve the power flow with the constraints of the DFIGs and the CNs. In Section 3, convergence of the DFIG is improved by modifying the flat start and solving the DFIG at the synchronous speed. In Section 4, numerical results to the DFIG and the test system with the DFIGs are given.
