Abstract

Environmental factors and electricity deficiency have led the Distribution System (DS) operators to promote the integration of renewable energy based Distributed Generation (DG), especially solar photovoltaics (PV). Need for obtaining sustained and maximized benefits in distribution operation, at reasonable rates of investment on DG integration, has driven the focus towards more accurate planning and a detailed impact analysis of DG on the DS. This paper proposes a detailed model of PV DG and multi-phase unbalanced DS; a generalized DS load flow (DLF) algorithm for steady-state analysis; and a multi criteria optimal integration of PV DG using Multi-Objective Particle Swarm Optimization (MOPSO) algorithm. The eveloped algorithms are implemented, in MATLAB coding environment, for a practical PV panel and an IEEE standard distribution test feeder. The effectiveness of the formulated PV modelling and DLF algorithms is confirmed by comparing the results obtained with PV panel name plate parameters and the results of the standard system, respectively. The optimal allocation of PV DG in the considered DS is furnished in the results.
