Hybrid power flow analysis: Combination of AC and DC models
This paper presents a hybrid approach with AC and DC power flow models for power flow analysis. Power flow problems are solved with the AC model in a part of system, whereas with the DC model in other parts. The proposed methodology can obtain benefits from both AC (non-linear) and DC (linear) models. In other words, this approach formulates both nonlinear and linear algebraic equations, and deals with tradeoff issues between accuracy of the AC model and faster solution of the DC model. A case study with an IEEE 14-bus system is provided to compare accuracy between the proposed and the DC model. It is shown that the hybrid approach can be used for applications requiring more accuracy than DC model allows.
