摘要：the development of smart distribution networks has become more flexible and changeable, making the interaction between transmission and distribution networks increasingly significant. When we list the inequality constraints of the whole-network voltage control model, we should consider the influence of voltage regulation in the transmission (distribution) network on the state variables of whole networks including transmission and distribution network, so it requires the sensitivity of the whole-network voltage/voltage-regulation controlled quantities. Generator regulates voltage in the transmission network and switching capacitors to regulate voltage in the distribution network are both common methods to regulate voltage. Using the idea of master slave splitting, the transmission network can exchange information with the distribution network, and sensitivity of whole networks voltage/controlled quantities of these two voltage regulation methods can be calculated. The result of simulation proves that the method proposed in this paper is accurate. © 2019 IEEE.
