Power Flow Calculation of Distribution Network with Distributed Power Sources based on Improved Newton Method
Aiming at the shortcomings of the existing power flow calculation methods in the distribution network with distributed power supply, a new power flow calculation method for the distribution network with distributed power supply is proposed. The processing methods of 4 different types of grid-connected nodes of distributed power supply are analyzed. The calculation rate of Jacobian matrix is increased by introducing two steps of predicted value and correction value in order to improve the sensitivity of Newton method to initial value. At last, IEEE33-node power distribution system is taken as an example to verify the correctness and performance of the improved Newton method, and its applicability to power flow calculation of distribution network with distributed power supply.
