Feeder Level Linear Voltage Drop Model for Active Radial Distribution System Operation in the Presence of Distributed Generation

In active distribution system, distributed generators require voltage drop management and power loss minimization. This paper proposes a voltage drop model and optimal management model for voltage drop and power loss including distributed generation (DG). The main focus of this work is to create a linear relationship between voltage drop and apparent power in the presence of DG. This is used to minimize voltage drop and power loss for a radial distribution feeder using minimization technique which comprises of DG real and reactive power control. Numerical analysis was done using IEEE 13 node test feeder system. Successful working of proposed model and minimization of line voltage drop, real and reactive power losses is demonstrated in this paper.
