Power Loss Minimization and Voltage Profile Assessment of Distribution System using WT-DG

Abstract

Due to adverse environmental change the integration of Distributed Generations (DGs) is gradually increasing in commercial and domestic power system. Hence, it is indispensable to investigate pros and cons of DGs before incorporating in existing network. Non-optimal size and placement of DGs will cause high active power losses in distribution systems and poor voltage profile. This paper presents a probabilistic approach to design of Wind Turbine (WT) distributed generation and its impact on distribution system. Monte Carlo simulation (MCS) has been used to incorporate the stochastic nature of wind variations. Matpower has been used in Matlab environment to design the radial network. All parameter of WT is carefully considered into the equivalent network. For any random wind velocity the WT power is represented as negative load. Current summation method has been used for power flow solution from Matpower. The proposed method has been tested on a 33-bus radial test system.
