摘要：

Because of the connection of distributed generation to energy complementary micro-grid, there are multi-supplying points and loop net which have serious influence on electric network tide and voltage regulation. Based on the models of different distributed generation and energy storage elements in power flow calculation, an unbalanced three-phase power flow calculation based on Newton method for micro-grid is presented. in view of three-phase unbalance and loop net of the micro-grid. The conventional steps of forming the Jacobian matrix, LU factorization and forward/back substitution in Newton method are replaced by back/forward sweeps on radial feeders with equivalent impedances, so that the calculation speed is proved. The example proved that the proposed method is efficient and feasible.
