Abstract

This article discusses the impact of direct current resistance on the distribution of the power of the DC power system of the MPPT when stabilizing direct current voltage. The resistance of the DC line in the multi-terminal MTDC system leads to changes in the voltage on the direct current with a change in power flow in the system. This, in turn, affects the distribution of instant power balance in the MTDC system during control in order to stabilize direct current voltage. The values of the direct current voltage reinforcement values determine the degree of influence of a reduction in direct current on the distribution of power balance in the DC system. In this article, a mathematical model was obtained to assess the distribution of power balance, taking into account the effect of direct current resistance. The MTDC system with five VSC-HVDC terminals was modeled in the Matlab/Simulink software package to demonstrate the impact of direct current resistance on the distribution of power balance, as well as to check the proposed mathematical model, which evaluates the distribution of power balance
