Optimized method on distributed reactive power compensation in lowvoltage distribution network based on interval power flow calculation

Abstract

Abstract:

The circuits are radially distributed in lowvoltage distribution network.The loads are unevenly distributed and of great uncertain change,and the voltage of terminal nodes is low.Thus,an optimization method on distributed reactive power compensation in lowvoltage distribution network based on interval power flow calculation is presented.The interval calculation is introduced based on NewtonRaphson power flow calculation model,and affine arithmetic is used in its convergence algorithm.The scope of reactive power shortage is calculated by interval power flow algorithm.The capacity and quantity of distributed capacitor banks of a lowvoltage power distribution network was determined by calculation and analysis.It is proved that he proposed method can improve the voltage quality of distribution networks effectively with great load fluctuations.
