Differential Privacy of Aggregated DC Optimal Power Flow Data [PDF]
, 2019 We consider the problem of privately releasing aggregated network statistics obtained from solving a DC optimal power flow (OPF) problem. It is shown that the mechanism that determines the noise distribution parameters are linked to the topology of the ...

Decomposed Iterative Optimal Power Flow with Automatic Regionalization
Energies, 2020 The optimal power flow (OPF) problem plays an important role in power system operation and control. The problem is nonconvex and NP-hard, hence global optimality is not guaranteed and the complexity grows exponentially with the size of the system ...

Convex Relaxations and Linear Approximation for Optimal Power Flow in Multiphase Radial Networks [PDF]
, 2014 Distribution networks are usually multiphase and radial. To facilitate power flow computation and optimization, two semidefinite programming (SDP) relaxations of the optimal power flow problem and a linear approximation of the power flow are proposed. We

Linear AC Three-Phase OPF Model for Active Distribution Networks with Unbalanced ZIP Loads
Brazilian Archives of Biology and Technology, 2022 : Although nonlinear Alternating Current (AC) Optimal Power Flow (OPF) may provide more accurate results compared to linearized OPF models, many ACOPF problems are complex and may require high, sometimes infeasible, computational time.
