Sentence examples for dc power flow from inspiring English sources
The static TEP problem is employed using DC power flow model.
Using the standard construct of the dc power flow approximation, this paper demonstrates that such a measure is easily defined analytically.
The subproblem would check dc network security constraints for the given UC solution to determine whether a converged and secure dc power flow can be obtained.
Results are presented for three standard test systems, and a comparison with the AC load flow results (and results obtained using DC power flow based distribution factors) shows that the method is fairly accurate.
In the proposed methodology, a DC power flow sub-problem is solved for each network resulting from adding a potential solution developed by the social spider algorithm to the base network.
In this paper, we present a single-objective optimization method that is applied to different case studies that include an AC and a DC power flow in order to consider losses accurate and efficiently.
