A novel distributed optimal power sharing method for radial dc microgrids with different distributed energy sources

A novel slack bus-free load flow method for dc microgrids and distribution systems with dc-bus signaling control methods

“…Figure 2 shows the block diagram of the control system of DBS control methods. Another merit of DBS control methods is their uncomplicated control system [9][10][11][12].…”

“…Considering these points, the existing distribution load flow methods used for conventional dc power systems cannot be applied to dc microgrids and distribution systems with DBS control methods. On the other hand, none of the literature dealing with DBS control methods proposed a proper load flow method for the dc power system.…”

“…The mentioned facts make DBS control methods distributed, autonomous, simple, highly reliable, inexpensive, modular and practical voltage control methods. According to their interesting characteristics, many literatures proposed DBS control methods for the voltage control of dc microgrids and distribution systems with different distributed power sources [8][9][10][11][12][13][14][15][16][17][18][19].According to the authors' research, no load flow method is specifically proposed for dc microgrids and distribution systems in literatures. The adapted versions of ac distribution load flow methods [20][21][22][23][24][25][26] are used for dc microgrids and distribution systems.…”

The generated power shares of the distributed power sources are not necessary input data for the presented load flow method.…”
