Abstrakt

The detailed topology of renewable resource bases may have the impact on the optimal power flow of the VSC-HVDC transmission network. To address this issue, this paper develops an optimal power flow with the hybrid VSC-HVDC transmission and active distribution networks to optimally schedule the generation output and voltage regulation of both networks, which leads to a non-convex programming model. Furthermore, the non-convex power flow equations are based on the Second Order Cone Programming (SOCP) relaxation approach. Thus, the proposed model can be relaxed to a SOCP that can be tractably solved. Numerical results on a three-bus VSC-HVDC network and the European system verify the effectiveness of the pro-posed model and suggest that the proposed model can guarantee the voltage magnitudes of both networks within the allowable ranges.
