Harmonic Power Flow Formulation based on the Linear Power Flow in Microgrids
2021 IEEE 5th Colombian Conference on Automatic Control (CCAC), 2021In this paper a harmonic power flow formulation for microgrids based on a power flow linearized through Wirtinger's calculus is presented. Through this formulation it is possible to calculate the harmonic power flow independently of the fundamental power

Error Bound Restriction of Linear Power Flow Model
IEEE Transactions on Power Systems, 2022Linear power flow models are widely used in power system analysis. To control the maximum influence of linearization error on decision making, it is important to evaluate the worst-case linearization error (i.e., the error bound). This letter theoretically derives the error bound of linear power flow models based on the truncation error analysis of ...

A Combination of Linear Power Flow Models to Reduce Linearization Error
2020 IEEE 3rd International Conference of Safe Production and Informatization (IICSPI), 2020The solution accuracy and efficiency of optimal power flow (OPF) calculation directly determine the economy and safety of power grid operation. The nonlinearity of power flow model leads the non-convex of the economic dispatch model. Linear power flow models are widely used in power systems. Based on general linear power flow model, we combine multiple

Linear power flow formulation for low-voltage DC power grids
Electric Power Systems Research, 2018Abstract This paper presents a reformulation of the power flow problem in low-voltage dc (LVDC) power grids via Taylor's series expansion. The solution of the original nonlinear quadratic model is achieved with this proposed formulation with minimal error when the dc network has a well defined operative conditions.

Truncation Error Analysis of Linear Power Flow Model
2020 IEEE Sustainable Power and Energy Conference (iSPEC), 2020The nonlinearity of the power flow equation is the significant cause of the non-convexity of optimization problems in the power system. The existing linear power flow model is derived based on special mathematical approximation and numerical analysis.
