Impact of load models on distribution system performance and impact of D-STATCOM

This paper presents the modelling of D-STATCOM for radial distribution system. The device is used to compensate the node voltage to 1 p.u and its effect is studied on constant power (CP) and generic ZIP model. With the device placement at each node real power, reactive power, size of reactive compensation and percent rate of under voltage mitigated nodes are calculated. The best location of the device is decided on the basis of power loss reduction and percent rate of under voltage mitigated nodes (RUVMN) separately. The effect of summer load variation on the D_STATCOM placement is also presented in this paper.
