Feasibility study of incorporating static compensators in distribution networks containing distributed generation considering system power factor

This paper investigates the economic feasibility of incorporating distribution-level static compensators (DSTATCOMs) in distribution systems containing distributed generation (DG) by considering the effect of DGs on the power drawn from the upper hand network. This effect is studied introducing distribution system power factor (dspf). To show the impact of DG placement on the dspf, common DG placement studies in the literature have been investigated. Additionally, an independent DG placement has also been carried out to examine this impact more thoroughly. The study has been performed and compared on standard as well as actual distribution systems using four different evolutionary optimization algorithms in order to ensure the validity of the obtained results and hence the applicability of the proposed method. It has been demonstrated that in most DG placements studies the impact of DGs on the dspf has not been properly taken into account. This leads to major financial loss for the system operator because of penalty costs due to low dspf. It has been demonstrated that the distribution companies can profit substantially by investing on DSTATCOMs, considering substantial decrease of penalty costs by improving the dspf.
