The increasing penetration of electric vehicles (EVs) and emerging dynamic wireless
charging techniques have strengthened the coupling between traffic networks and power …

In many parts of the world, electric power systems have seen a significant shift toward
generation from renewable energy and natural gas. Because of their ability to flexibly adjust …

In this work, we develop an adaptive, multivariate partitioning algorithm for solving
nonconvex, Mixed-Integer Nonlinear Programs (MINLPs) with polynomial functions to global …

Increasing use of natural gas for electricity production places added strains on pipeline
systems that are used for transporting fuel. Pipeline constraints require power system …

The variability in the generation dispatch of the natural gas generation units will lead to
fluctuation in natural gas demand profile that could further jeopardize the security of the …

We extend the canonical problems of simulation and optimization of steady-state gas flows
in pipeline networks with compressors to the transport of mixtures of highly heterogeneous …

Load tap changers (LTCs) are commonly used for voltage control in distribution systems.
The mechanical relays on LTCs are controlled in discrete steps; hence, distribution optimal …

Since the alternating current optimal power flow (ACOPF) problem was introduced in 1962,
developing efficient solution algorithms for the problem has been an active field of research …

Considering the increased trend that power systems are closer to the operating bounds
because of the increased demand and new challenges in consideration of gas systems and …

We formulate a steady-state network flow problem for nonideal gas that relates injection
rates and nodal pressures in the network to flows in pipes. For this problem, we present and …
