Abstract:
This paper presents a novel analytical approach to estimate the optimal generation profiles/size and location of a distributed generation (DG) unit that can be
integrated into distribution network to attain the lowest level of active loss. This
approach considered the impact of significant parameters including daily load
profiles, best power limits of a DG unit, and varying injected power profiles of
the substation on results of minimum active loss of the distribution network
and optimal calculations of DG. Additionally, the DG placement was speedily
identified in this approach by using a new active loss expression along with four
different scenarios. These scenarios considered a number of assumptions on the
load profiles and on the state variables (voltage and angle). The obtained optimal active generation profile was also used to manage the uncertainty in the
energy of the wind and photovoltaic distribution generators for achieving the
highest loss reduction. Additionally, the exhaustive load flow method was used
to check the validity of the analytical approach by using 13‐bus and 69‐bus
distribution networks. The results obtained suggest the effectiveness of this
approach in estimating the optimal location and profile/size of DG.
