(author), Hoogenberg, Bas Jan (author), Dantuma, Sybren (author), Hollmann, F. (author), De Vries, Jan Willem (author)Engineered viruses are finding an increasing number of applications in basic, translational research and materials science. Genetic and chemical engineering of capsids represents a key point for tailoring the properties of viral particles, but the synthetic efforts and limits accompanying these processes still hinder their usability. Here, a...journal article 2019

Poplavskaya, K. (author), De Vries, Laurens (author)Thanks to new technological advancements and EU policy impulse, distributed energy resources (DER) are poised to become a viable alternative to conventional electricity generation for the provision of balancing services to transmission system operators. In this paper we show that the design variables that affect DER access to and...journal article 2019

Philipsen, R.M. (author), Morales-Espana, G. (author), de Weerdt, M.M. (author), De Vries, Laurens (author)Day-ahead electricity markets are inefficient due to their coarse discretisation of time and their representation of electricity production and consumption in energy per time interval. This leads to excessive costs and infeasible schedules in the market clearing results. Some real-world systems have increased the resolution to improve accuracy,...journal article 2019

Piao, L. (author), De Vries, Laurens (author), de Weerdt, M.M. (author), Yorke-Smith, N. (author)DC distribution systems (DCDSs) are a promising alternative to AC systems because they remove AC-DC conversions between renewable sources and loads. Their unique features compared to AC include low system inertia, strict power limits and power–voltage coupling. In a liberalised electricity market, merely applying an AC market design to a DCDS...journal article 2019

Klein, Martin (author), Ziade, Ahmad (author), De Vries, Laurens (author)PV-battery systems are currently not operated in an energy system optimal way as their operation heuristic (maximization of self-consumption) is generally unaffected by competitive market signals. To evaluate potential regulatory intervention, we propose a market alignment indicator which measures the relative economic efficiency of a prosumer...journal article 2019

Khan, A.S.M. (author), Verzijlbergh, R.A. (author), Sakinci, Ozgur Can (author), De Vries, Laurens (author)To ensure security of supply and incentivize reliable investment in generation capacity, capacity markets (CMs) have been implemented or are being considered. However, demand response (DR) and electrical energy storage (EES) also contribute to system adequacy. In this paper, we analyse the change in the need for a CM if DR and EES are...journal article 2018

De Vries, Laurens (author), Verzijlbergh, R.A. (author)We present a systematic review of the challenges to the regulation of electricity markets that are posed by the integration of variable renewable energy sources. System integration is the key to developing the required flexibility, because flexibility options exist at all system levels and within the competitive as well as in the regulated ...journal article 2018

Piskorz, T.K. (author), De Vries, Alex H. (author), De Feyter, Steven (author), van Esch, J.H. (author)Ostwald ripening can improve the long-range order of self-assembled monolayers by the growth of large domains and disassembly of smaller ones. Here, coarse-grained molecular dynamics simulations are used to study the dynamics of the stable assembly and the coarsening of defects of physisorbed monolayers of long-chain functionalized alkanes....journal article 2018

Verzijlbergh, R.A. (author), De Vries, Laurens (author), Dijkema, G.P.J. (author), Herder, P.M. (author)The integration of large amounts of variable renewable energy poses fundamental challenges to the operation and governance of the energy system. In this article we address the main institutional challenges that are caused by the integration of variable renewable energy sources like solar and wind energy in the European power system. We first...journal article 2017

Bhagwat, P.C. (author), Richstein, J.C. (author), Chappin, E.J.L. (author), Iychettira, K.K. (author), De Vries, Laurens (author)The cross-border effects of a capacity market and a strategic reserve in interconnected electricity markets are modeled using an agent-based modeling methodology. Both capacity mechanisms improve the security of supply and reduce consumer costs. Our results indicate that interconnections do not affect the effectiveness of a capacity market,...journal article 2017

(author)We present an approach to simulate climate and energy policy for the EU, using a flexible and modular agent-based modelling approach and a toolbox, called the Energy Modelling Laboratory (EMLab). The paper shortly reviews core challenges and approaches for modelling climate and energy policy in light of the energy transition. Afterwards, we...journal article 2017

Bhagwat, P.C. (author), Iychettira, K.K. (author), Richstein, J.C. (author), Chappin, E.J.L. (author), De Vries, Laurens (author)The effectiveness of a capacity market is analyzed by simulating three conditions that may cause suboptimal investment in the electricity generation: imperfect information and uncertainty; declining demand shocks resulting in load loss; and a growing share of renewable energy sources in the generation portfolio. Implementation of a capacity...journal article 2017

Bhagwat, P.C. (author), Marcheselli, A. (author), Richstein, J.C. (author), Chappin, E.J.L. (author), De Vries, Laurens (author)We analyze the effectiveness of a forward capacity market (FCM) with long-term contracts in an electricity market in the presence of a growing share of renewable energy. An agent-based model is used for this analysis. Capacity markets can compensate for the deteriorating incentive to invest in controllable power plants when the share of...journal article 2017

(author), Nguyen, Binh Minh (author), Kouwenhoven, Leo P. (author)The spin-orbit interaction is investigated in a dual gated InAs/GaSb quantum well. Using an electric field, the quantum well can be tuned between a single-carrier regime with exclusively electrons as carriers and a two-carrier regime where electrons and holes coexist. The spin-orbit interaction in both regimes manifests itself as a beating in...journal article 2017
