Geometry of Distance Protection
Josh A. Taylor, Alejandro D. Domínguez-García
Distance relays detect faults on transmission lines. They face uncertainty from the fault's location and resistance, as well as the current from the line's remote terminal. In this…
Auxiliary Signal-Based Distance Protection in Inverter-Dominated Power Systems
Josh A. Taylor, Alejandro D. Domínguez-García
Power system protection schemes today rely on currents rising by several orders of magnitude when faults occur. In inverter-dominated power systems, a fault current might be just a…
Information Structures in AC/DC Grids
Josh A. Taylor
The converters in an AC/DC grid form actuated boundaries between the AC and DC subgrids. We show how in both simple linear and balanced dq-frame models, the states on either side o…
Convex optimization of bioprocesses
Josh Taylor, Alain Rapaport, Denis Dochain
We optimize a general model of bioprocesses, which is nonconvex due to the microbial growth in the biochemical reactors. We formulate a convex relaxation and give conditions guaran…
Second-order cone optimization of the gradostat
Josh Taylor, Alain Rapaport
We maximize the production of biogas in a gradostat at steady state. The physical decision variables are the water, substrate, and biomass entering each tank and the flows through…
Optimal Water-Power Flow Problem: Formulation and Distributed Optimal Solution
Ahmed S. Zamzam, Emiliano Dall'Anese, Changhong Zhao +2
This paper formalizes an optimal water-power flow (OWPF) problem to optimize the use of controllable assets across power and water systems while accounting for the couplings betwee…
A concise, approximate representation of a collection of loads described by polytopes
Suhail Barot, Josh A. Taylor
Aggregations of flexible loads can provide several power system services through demand response programs, for example load shifting and curtailment. The capabilities of demand res…
