Derivation-free Steady State Power Flow Calculation Approach for HVDC Systems with Distributed DC Voltage Control and Arbitrary p-v-Characteristics

An efficient power flow calculation is necessary for the optimization of HVDC systems. For a decentralized approach of the DC voltage control, there are several different functions. In this paper an efficient derivation-free solver for the DC power flow calculation is presented, which is applicable for arbitrary control functions without determining the derivation of the function. The applied method is evaluated by a sample calculation, which compares the results of the static calculation with a dynamic simulation.
