Integration of Inverter Based Resources (IBRs) in the distribution grid and bulk grid has posed new challenges to the long-term voltage stability of the integrated electric Transmission and Distribution (T&D) system. The main challenges include, but are not limited to, IBR variability and intermittence, the effect of a large number of DERs, distribution grid unbalances, the effect of load types, and the interaction of controllable devices such as voltage regulators. This paper proposes a new three-sequence integrated T&D continuation power flow (SI-CPF) model for analyzing the voltage stability of the power grid considering, grid and load unbalance, various load types, and renewable energy variations, in a combined T&D simulation that consider all the phases of transmission and distribution network. Results show that SI-CPF can provide the weak phase voltage stability margin of the power grid more efficiently and accurately considering a three-phase integrated T&D network.
