A novel DG allocation method for power loss reduction in radial distribution system

The objective of this paper is to minimize active power losses of radial distribution system by optimal Distributed Generations (DGs) allocation. The significance of optimal DG allocation is to offer the appropriate position and sizes of DG units. A novel constant, Power Voltage Sensitivity Constant (PVSC), has been proposed in this paper to solve the problem. The type-I DG, which gives only active power, is considered here. The level of DG penetration is considered in a range of 0-50%. The achievability of the technique has been verified on 69 bus standard system at different load level. The results are encouraging when compared with latest approach.
