Wang, N. (author), Verzijlbergh, R.A. (author), Heijnen, P.W. (author), Herder, P.M. (author)Energy system optimization models are widely used to aid long-term investment decision-making for energy systems. From a socio-technical system viewpoint, existing models focus on the cost modeling of the technical subsystem, while the indirect costs of the social subsystem are not often modeled. This paper incorporates indirect costs into such...journal article 2023

Baas, Peter (author), Verzijlbergh, R.A. (author), van Dorp, Pim (author), Jonker, H.J.J. (author)As a consequence of the rapid growth of the globally installed offshore wind energy capacity, the size of individual wind farms is increasing. This poses a challenge to models that predict energy production. For instance, the current generation of wake models has mostly been calibrated on existing wind farms of much smaller size. This work...journal article 2023

Taschner, E. (author), van Vondelen, A.A.W. (author), Verzijlbergh, R.A. (author), van Wingerden, J.W. (author)The performance of wind farms can substantially increase when their individual turbines deviate from their own greedy control strategy and instead also take into account downstream turbines operating in the wake. The helix approach is a recently introduced dynamic wind farm control strategy that tackles this issue by leveraging individual...journal article 2023

Taschner, E. (author), Folkersma, M.A.M. (author), A Martínez-Tossas, Luis (author), Verzijlbergh, R.A. (author), van Wingerden, J.W. (author)The development of new wind farm control strategies can benefit from combined analysis of flow dynamics in the farm and the behavior of individual turbines within one simulation environment. In this work, we present such an environment by developing a new coupling between the large-eddy simulation (LES) code GRASP and the multiphysics wind...journal article 2023

Neustroev, G. (author), Andringa, S.P.E. (author), Verzijlbergh, R.A. (author), de Weerdt, M.M. (author)Wind farms suffer from so-called wake effects: when turbines are located in the wind shadows of other turbines, their power output is substantially reduced. These losses can be partially mitigated via actively changing the yaw from the individually optimal direction. Most existing wake control techniques have two major limitations: they use...conference paper 2022

Stawska, A.M. (author), Lane, N.R. (author), de Weerdt, M.M. (author), Verzijlbergh, R.A. (author)The growing capacity of intermittent energy sources causes more frequent system imbalances as well as congestion. Demand flexibility is a valuable resource that can be used to resolve these. Unfortunately, flexibility can also contribute to congestion, particularly when used to balance the grid. Using flexibility to solve grid problems...journal article 2021

Wang, N. (author), Verzijlbergh, R.A. (author), Heijnen, P.W. (author), Herder, P.M. (author)This paper reviews the literature on the modeling approaches on decentralized energy investment and operation in the prosumer era. The study has several contributions. Firstly, it adds investment models into the review which have not been previously reviewed for decentralized energy modeling. Secondly, a modeling framework consisting of four...conference paper 2020

Chakraborty, S.T. (author), Verzijlbergh, R.A. (author), Lukszo, Z. (author)Price volatility in electricity markets could significantly increase as a result of the increase in demand due to the electrification of heating and transport and intermittent power generation from large scale integration of renewable energy sources. In some parts of the grid, price volatility may be even more extreme due to congestion....conference paper 2020

Chakraborty, S.T. (author), Verzijlbergh, R.A. (author), Baker, Kyri (author), Cvetkovic, M. (author), De Vries, Laurens (author), Lukszo, Z. (author)Recently, given the increased integration of renewables and growing uncertainty in demand, the wholesale market price has become highly volatile. Energy communities connected to the main electricity grid may be exposed to this increasing price volatility. Additionally, they may also be exposed to local network congestions, resulting in price...journal article 2020

Wang, N. (author), Verzijlbergh, R.A. (author), Heijnen, P.W. (author), Herder, P.M. (author)Variable Renewable Energy Sources (VRES) are characterized by intensive land-use and variable production. In existing optimization models that minimize the total cost of the energy system, location-specific VRES production profiles are often used to estimate VRES potential, but land-use and land cover aspects have been largely ignored. In this...journal article 2020

Chakraborty, S.T. (author), Verzijlbergh, R.A. (author), Lukszo, Z. (author), Cvetkovic, M. (author), Baker, Kyri (author)Locational Marginal Price (LMP) is a dual variable associated with supply-demand matching and represents the cost of delivering power to a particular location if the load at that location increases. In recent times it become more volatile due to increased integration of renewables that are intermittent. The issue of price volatility is...conference paper 2019

Neustroev, G. (author), de Weerdt, M.M. (author), Verzijlbergh, R.A. (author)Infinite-horizon non-stationary Markov decision processes provide a general framework to model many real-life decision-making problems, e.g., planning equipment maintenance. Unfortunately, these problems are notoriously difficult to solve, due to their infinite dimensionality. Often, only the optimality of the initial action is of importance to...conference paper 2019

(author)Dutch regional municipalities increasingly take an active role in the transition to more sustainable and autonomous energy supply systems, using local energy sources like wind, solar and biomass. The ambition, on the one hand, concerns how an optimal local energy supply system can be designed such that local energy targets can be realized with...abstract 2018

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

Verzijlbergh, R.A. (author)Electric vehicles (EVs) have the potential to play a crucial role in clean and intelligent power systems. The key to this potential lies in the flexibility that EVs provide by the ability to shift their electricity demand in time. This flexibility can be used to facilitate the integration of renewable energy sources by adjusting EV demand to the...doctoral thesis 2013
