Special loads integrated into distribution network inevitably have negative effects on voltageprofile and network loss

due to their nonlinearity

impact resistance

fluctuation

and unbalancecharacteristics. This paper first analyses the impact of the integration of metro-based loads intodistribution network on voltage profile. Then

a multi-scenario reactive power optimization model fordistributed network considering special loads is proposed

in which the trade-off between the rate ofvoltage profile improvement

network loss rate

and investment payoff period is the objective

whilesatisfying the normal operation constraints. Finally

the proposed model is solved by using the directcomparison method and then the optimal compensation scheme is obtained. The simulation results haveverified the effectiveness and practicability of the proposed method in distribution network consideringspecial metro-based loads.
