Based on the distributed harmonic control scheme of digital distribution network

considering the auxiliary harmonic control function of multi-functional grid-tied inverter（MFGTI）

An optimal configuration strategy of Voltage Detection Active Power Filter（VDAPF） considering the contribution of MFGTI is proposed.Firstly

the VDAPF and MFGTI coordinated harmonic control zoning method is introduced to determine the best installation location of VDAPF.Secondly

the dual uncertainties of harmonics and MFGTI are constructed by using scenario analysis.Then

a multi-objective VDAPF capacity optimal allocation model is built

and both economic and governance effects are taken into account.Normalized Normal Constraint（NNC） is used to transform the multi-objective model into a single objective model for solution.Finally

an IEEE33 node distribution system is taken as an example for simulation verification.The results show that considering the governance function of MFGTI in the configuration of VDAPF can achieve better economic and governance effects

and the effectiveness of the proposed strategy is verified.
