Abstract
A two-stage model for optimizing planning of distribution system with the presence of DG is presented in this paper. The proposed model can determine optimal upgrading sizing and timeframe of equipments (feeders and transformer substations) in distribution system. Hence, optimal displacement, sizing, technology and installation period of DG are also determined. The model’s the objective function is life cycle cost to seek minimum costs for the planning scheme. The technical constraints are used to guarantee operability of the distribution system including AC power flow, feeder and substation upgrading section, limited of nodal voltage and DG capacity. Binary variables are also used in the model to represent the cost characteristic of equipments as well as investment and upgrade decisions. The calculation program is made in GAMS environment. The feasibility and effectiveness of the proposed model are examined by a 7-bus test system
