- Plenty of transmission substations in large scale power system are designed to deliver power to electricity users far away from power plants, and most of them can be seen as interconnecting (IC) nodes. Interconnecting node has the characteristic of zero power injection, thereafter causes zero current injection to the power system. A novel power flow calculation model is proposed, based on the elimination of IC node equations, to get more fast power flow calculation. The power network equations of IC nodes are eliminated so as to reduce the total dimension of the power flow model. Then, element-wise Jacobian matrix are deduced according to the reduced system power balance equations, in relationship to partial voltage vectors of non-interconnecting nodes. Tests on IEEE standard systems are then performed to validate the proposed method, and computation efficiency are compared with the traditional formulation of power flow model.
