Statistical Analysis for Active Power Loss Incorporating Distributed Generation in Distribution System

A statistical investigation of real power loss in radial distribution system (RDS) incorporating distributed generation (DG) is presented. Statistical parameters for real power loss is obtained by Monte Carlo simulation (MCS). Samples for power loss is obtained by load flow technique. IEEE- 33 bus RDS is considered for the purpose. Load demands at buses have been treated as continuous random variable (CRV) assumed as Gaussian distributed. Moreover optimal buses for DG placement are selected by incremental power loss sensitivity criteria at selected locations. DG capacities have been integrated and considered as a Gaussian distributed. This paper not only gives statistical parameters but also evaluates probability distribution function and cumulative distribution function for RDS.
