摘要：A two-stage model for the optimal planning of distribution systems with the presence of photovoltaic generation system (PV) is presented in this paper. The proposed model can determine the optimal sizing and timeframe of the equipment (feeders and transformer substations) in distribution systems. Therefore, the optimal displacement, sizing, technology and installation period of PV are also determined. The objective function is minimizing the life cycle costs of the planning project. The technical constraints are used to guarantee the operability of the distribution system including AC power flow, feeder and substation upgrading section, limited of nodal voltage and PV capacity. The binary variables are also employed in the model to represent the cost function of the equipment as well as the investment and upgrade decisions. The algorithm is programmed in GAMS environment. The feasibility and effectiveness of the proposed model are examined in a 7-bus test system.
