In DAKAR, the load flow calculation is performed using the compensational electromotance method (based on the optimization of Jacobi matrix conditioning and per-node Newton linearization).
This method is characterized by the electric condition being balanced during each iteration.
This method allows to calculate normal, marginal, and post-emergency conditions with or without frequency alteration. In case of frequency change, the power system can be divided into several subsystems with different frequency values in them.
DAKAR allows to optimize network modes of 10-750 kV by voltages, using the method of position selection of on-load tap changer (OLTC), No-load tap changer (NLTC), and TPR autotransformers.
To ensure the desired voltage levels, the automatic position selection of the on-load tap-changers transformers is implemented.
