Coordinated Planning of Distributed Generation and Distribution Networking Considering Network Reconfiguration
2018
This paper presented a multistage mixed-integer second order conic programming (MISOCP) model for the coordinate planning of distributed generation (DG) and distribution network. Aimed at minimizing the present value of total construction costs and operation costs in the county grid with high DG penetration, following factors are considered: 1) reconfiguration of the distribution network in different scenarios; 2) reverse power injected to the grid; 3) expansion alternatives of feeders and substations. The proposed model uses second order conic relaxation as an approximation of quadratic constraints. Effectiveness of the model was tested on the JinZhai distribution network, which is a practical network with a large-scale integration of photovoltaic DGs. Results of DG planning and coordinate planning were simulated and compared.
