The increasing demand and the corresponding rising penetration of renewable energy
generation has brought various challenges for the power system. In this regard, expansion …

Transmission network expansion planning (TNEP) is a significant problem in the field of the
power system. The TNEP deals with the required expansion of the existing networks in the …

This paper proposes an accurate model to solve the transmission network expansion
planning (TNEP) problem. The TNEP problem is solved using a linear DC model, a mixed …

Metodología: Se basa en linealizar las ecuaciones del OPF-AC mediante Series de Taylor,
para obtener un problema linealizado. Resultados: El modelo determina cuales son las …

This paper studies mixed-integer nonlinear programs featuring disjunctive constraints and
trigonometric functions and presents a strengthened version of the convex quadratic …

The alternating-current optimal power flow (ACOPF) is one of the best known non-convex
nonlinear optimization problems. We present a novel re-formulation of ACOPF, which is …

Recent years have witnessed the success of employing convex relaxations of the AC
optimal power flow (OPF) problem to find global or near-global optimal solutions. The …

There has been much recent interest in hierarchies of progressively stronger
convexifications of polynomial optimisation problems (POP). These often converge to the …

This article deals with optimal transmission switching (OTS) problems involving binary
decisions about network topology and nonconvex power flow constraints. We adopt a …

Abstract The Entry–Exit System. The liberalization of the European gas markets started in
the 1990s and lead to the current situation in which European transmission system …
