Control Strategies for Variable Speed Operation of Pumped Storage Plants with Full-size Converter Fed Synchronous Machines
(Chapter; Peer reviewed, 2021)The full-size converter fed synchronous machine (CFSM) for variable speed operation of a pumped storage power plant exhibits multiple advantages over the state-of-the-art Doubly Fed Induction Machine (DFIM) technology. The ... -
Control system for start-up and shut-down of a floating vertical axis wind turbine
(Peer reviewed; Journal article, 2013)A baseline control system for the Deepwind floating vertical axis wind turbine (VAWT) concept is analysed with em- phasis on start-up and shut-down schemes. The turbine concept includes a rotating spar with a 2-bladed rotor ... -
Convergence properties of detonation simulations

Convex Optimization-based Control Design for Parallel Grid-Connected Inverters
(Journal article; Peer reviewed, 2018)This paper presents a novel frequency-domain approach towards the control design for parallel grid-connected voltage source inverters (VSIs) with LCL output filters. The proposed method allows to design the controllers of ... -
Convex Relaxations of the Short-Term Hydrothermal Scheduling Problem
(Peer reviewed; Journal article, 2020)This paper concerns the assessment of two methods for convex relaxation of the short-term hydrothermal scheduling problem. The problem is originally formulated as a mixed integer programming problem, and then approximated ... -

Coordinated Voltage Support with Reactive Power from High-power Charging Stations for EVs
(Chapter; Peer reviewed, 2021)High-power charging stations have recently drawn the attention of many researchers and electric vehicle (EV) infrastructure industries. However, the installation of fast chargers at various corridors of highways and cities ... -
Correlation effects between turbulence and the conversion rate of pulverized char particles
(Journal article; Peer reviewed, 2017)The effect of turbulence on heterogeneous reactions on the surface of char particles embedded in a turbulent oxidizer, consisting of oxygen and carbon-dioxide, is in this work studied numerically. It is shown that for a ... -
Corrosion performance of different alloys exposed to HTL conditions – a screening study
(Peer reviewed; Journal article, 2024)The corrosion and material evaluation study in (a) water-based simulated black liquor and (b) water-based simulated black liquor at super-critical conditions was successful. The conclusion from the testing program was that ... -
Cost-Benefit Analysis of Battery Energy Storage in Electric Power Grids: Research and Practices
(Chapter; Peer reviewed, 2020)This paper provides an overview of methods for including Battery Energy Storage Systems (BESS) into electric power grid planning. The general approach to grid planning is the same with and without BESS, but when BESS is ... -
Cost-optimal CO2 capture ratio for membrane-based capture from different CO2 sources
(Journal article, 2017)This paper investigates the cost reduction opportunity of lower CO2 capture ratios (CCR) on membrane-based CO2 capture. A numerical model based on the Attainable Region approach is used to optimise and assess the cost of ... -
Costs benchmark of CO2 transport technologies for a group of various size industries
(Journal article; Peer reviewed, 2013)This paper summarizes key results from the Collaborative COCATE Project for the European Commission (FP7). The costs of transporting a total of 13.1 MtCO2/y from small- to large-scale emitters around Le Havre (France), to ... -
