Equivalence of Inverter Node Type in Power Flow Calculation and Power Flow Calculation for Robust Droop Control Node
摘要
Abstract
Power flow calculation plays an important role in the power system analysis.In the power flow calculation of microgrid,inverter nodes often need to be converted into PQ or PV nodes by using the node type equivalent method. However,the conditions of node type equivalence are closely related to the strategy of inverter control.Comparing to filter parameters of inverters and transmission line impedance of microgrid,this paper summarizes the characteristics of inverter controller suitable for power flow calculation of microgrid.For the robust droop controller presented in recent years,the power flow calculation model is established.Based on the Newton method,the modified equation of power flow calculation is set up to solve the power flow.Finally,a European 20-node autonomous microgrid is set up to verify the effectiveness of the algorithm.关键词
