Equilibrium Conductance Compensation Symmetry Method for Obtaining Power Transfer Coefficient of DC Power Network

A symmetrical method of balanced conductance compensation for obtaining the power transmission coefficient of DC power network is presented. Firstly, a global linear relationship (101) of balanced conductance compensation for node injection power with respect to node translation voltage is established according to node load parameters and node power supply parameters of DC power network. Then, the steady-state equilibrium of DC power network is established based on the global linear relationship of balanced conductance compensation. Conductivity compensation global linear symmetry model (102); using M_P inverse matrix to establish the equilibrium conductivity compensation global linear symmetry matrix relation (103) of the translation voltage of the whole network node with respect to the injection power of the whole network node; then establishing the equilibrium conductivity compensation global linear symmetry relation (104) of branch transmission power with respect to the injection power of the whole network node; finally, according to the equilibrium conductivity compensation global. Linear symmetric relation is used to obtain the power transmission coefficient (105) of DC power network, which achieves high accuracy, fast and reliable calculation, and improves the accuracy and real-time of regulation and control when the operation state of power network changes in a wide range.
