文摘

A method on injecting active power balance namely the improved P-V droop coefficient is presented to ensure proportional load sharing among the parallel inverters under different connection line impedance. The relation among the modified P-V droop coefficient, the connection line impedance and the load is obtained quantitatively. The modified coefficient iterative algorithm is presented for the simple engineering application to obtain the limited variable range
