Optimal Power Flow Using an Extended Conic Quadratic Formulation

摘要: Recent research has shown that the load flow equations describing steady-state conditions in a meshed network can be placed extended conic quadratic (ECQ) format. This paper presents study of implementation new format an optimal power (OPF) program which accounts for control devices such as tap-changing transformers, phase-shifting and unified controllers. The proposed OPF representation retains advantages ECQ format: 1) it easily integrated within optimization routines require evaluation second-order derivatives, 2) efficiently solved using primal-dual interior-point methods, 3) make use linear programming scaling techniques improving numerical conditioning. ECQ-OPF is employed to solve economic dispatch active loss minimization problems. Numerical testing used validate approach by comparing against solution methods results standard test systems.
