Power flow algorithm of DC distribution network with distributed energy access
Compared with AC distribution network, DC distribution network has advantage in less line loss, large power supply capacity, good power quality, etc., but in the acceptance of distributed energy storage and energy storage also has certain advantages.

Summary: | Compared with AC distribution network, DC distribution network has advantage in less line loss, large power supply capacity, good power quality, etc., but in the acceptance of distributed energy storage and energy storage also has certain advantages. This paper established a DC/AC converter steady-state model, which can access the photovoltaic, wind power and other distributed energy; and also established other DC element model like DC energy storage and DC load. On the basis of steady-state DC distribution network model, this paper applies VSC based MHVDC power flow algorithm to DC distribution network, and improve the original algorithm for the access of distributed energy, DC energy storage and DC load forming the DC distribution network power flow algorithm. Finally, the proposed algorithm is applied to an altered IEEE33 bus example to verify the correctness of the algorithm. |
