英文摘要 | This paper deals with the modeling and simulation of random variation of three-phase voltage unbalance caused by load fluctuation in the distribution system. Active and reactive powers delivered by each phase to a distribution feeder are modeled by six correlated Gaussian random variables. Application of the Cholesky decomposition method allows the correlated Gaussian random variables to be effectively simulated using the Monte Carlo technique. This is followed by a simple iterative process for solving the load flow problem so that three-phase voltage phasors at the point of common coupling (PCC) can be obtained and random variation of voltage unbalance factor at the PCC can be evaluated. |
