Load Flow Solution for Unbalanced Radial Power Distribution using Monte-Carlo Simulation
Authors: , ,
Abstract: In modern power system, voltage stability is a major concern. To maintain voltage stability, it is desirable to assess effect of any unforeseen events and identify the nodes which are more sensitive. The most important task for distribution engineer is to efficiently simulate the system so that effective corrective actions can be taken. Load flow analysis is one of the techniques to simulate the system. This paper presents a probabilistic modeled load flow solution for three phase Radial Power Distribution System (RDS). Probabilistic model uses Monte Carlo Simulation (MCS) and considers input parameters as random variables. Input uncertainties are addressed using a specific shape of probability distribution function and simulation is run for 500 trails. Simulation calculates system losses, nodal voltages and voltage stability index (SI) for all the nodes. The simulation results obtained incorporates the uncertainty and provides distribution of output which can be used as input for corrective action and planning purposes
