Menon, Akash (author)During dynamic positioning operations, vessels typically run with an extra generator (spinning reserve) for redundancy purposes such that no single fault will cause the vessel to lose its position or heading. As a result, all other engines on the grid share the load equally to ensure that if a failure were to occur, the remaining healthy...master thesis 2019

Evans, Michael (author), Angeli, David (author), Strbac, Goran (author), Tindemans, Simon H. (author)We present a method to find the maximum magnitude of any supply-shortfall service that an aggregator of energy storage devices is able to sell to a grid operator. This is first demonstrated in deterministic settings, then applied to scenarios in which device availabilities are stochastic. In this case we implement chance constraints on the...conference paper 2019

Sanchez, Francisco (author), Cayenne, Joshua (author), González-Longatt, Francisco (author), Rueda, José L. (author)The increased adoption of renewable energy generation is reducing the inertial response of the Great Britain (GB) power system, which translates into larger frequency variations in both transient and pseudo-steady-state operation. To help mitigate this, National Grid, the transmission system operator in GB, has designed a control scheme...journal article 2019

Evans, Michael P. (author), Tindemans, Simon H. (author), Angeli, David (author)This paper considers the optimal dispatch of energy-constrained heterogeneous storage units to maximize security of supply. A policy, requiring no knowledge of the future, is presented and shown to minimize unserved energy during supply-shortfall events, regardless of the supply and demand profiles. It is accompanied by a graphical means to...journal article 2019

Serna Suarez, I.D. (author), Carrillo-Caicedo, Gilberto (author), Morales-Espana, G. (author), de Weerdt, M.M. (author), Ordóñez-Plata, Gabriel (author)The increase of solar photovoltaic penetration poses several challenges for distribution network operation, mainly because such high penetration might cause reliability problems like protection malfunctioning, accelerated decay of voltage regulators and voltage violations. Existing solutions based on mathematical programming solve a 3-phase...journal article 2019

Fakhri Muhammad, Tubagus (author)Electric Vehicles (EVs) provide a promising sustainable clean mode of transportation with much fewer emissions compared to the traditional Internal Combustion Engine (ICE) vehicles. However, this can only be considered true if the energy sources used for charging EVs are also from clean energy form. Various Renewable Energy Sources (RES) are...master thesis 2018

Noris Martinez, Leonel (author)Power outages can damage severely critical infrastructures such as telecommunication networks, financial services, water supplies and hospitals and completely shutting down production at companies. While most power blackouts usually last from some minutes to few hours, some can last days or even weeks. Furthermore, it is likely that these kinds...master thesis 2018

Schouhamer Immink, Kees A. (author), Cai, Kui (author), Weber, J.H. (author)We consider the transmission and storage of encoded strings of symbols over a noisy channel, where dynamic threshold detection is proposed for achieving resilience against unknown scaling and offset of the received signal. We derive simple rules for dynamically estimating the unknown scale (gain) and offset. The estimates of the actual gain...journal article 2018

de la Garza Cuevas, Roberto (author)Airborne Wind Energy is a promising technology that is becoming the point of interest for many applications. One market in which the AWE systems can open a path as a renewable distributed generator is in offgrid communities or camps. Nowadays, this market is dominated by fossil fuel energy like diesel generators. Even though the diesel is cheap,...master thesis 2018

Rostampour, Vahab (author), Keviczky, T. (author)This paper presents an energy management framework for building climate comfort (BCC) systems interconnected in a grid via aquifer thermal energy storage (ATES) systems in the presence of two types of uncertainty (private and common). ATES can be used either as a heat source (hot well) or sink (cold well) depending on the season. We consider...journal article 2018

Gavric, M. (author)Voltage drop and rise at network peak and off-peak periods are one of the major power quality problems in low voltage distribution networks. Additionally, the ever increasing demand for electricity along with the other requirements are driving modern day power systems towards more distributed generation (DG). Integration of large scale DG can be...master thesis 2016
