The excess of short circuit currents (SCC) has threatened the security of electrical energy transmission and become one of the most critical problems in power grid operations. At present, high voltage direct current (HVDC) transmission technology is a practical and applicable option to limit short circuit currents by separating a synchronous power grid into several asynchronous power grids. During...
An approach of transmission network expansion planning with embedded constraints of short circuit currents and N-1 security is proposed in this paper. The problem brought on by the strong nonlinearity property of short circuit currents is solved with a linearization method based on the DC power flow. The model can be converted to a mixed-integer linear programming problem, realizing the optimization...
