Shengren, H. (author), Vergara Barrios, P.P. (author), Salazar Duque, Edgar Mauricio (author), Palensky, P. (author)The massive integration of renewable-based distributed energy resources (DERs) inherently increases the energy system’s complexity, especially when it comes to defining its operational schedule. Deep reinforcement learning (DRL) algorithms arise as a promising solution due to their data-driven and model-free features. However, current DRL...journal article 2023

Li, N.L. (author), Okur, Ö. (author)Energy communities play an important role in the energy transition to future clean and sustainable energy. The economic feasibility of an energy community is largely affected by its investment options: either a third party or households themselves can invest in distributed energy resources. Another common problem for energy communities is cost...journal article 2023

Feng, Cheng (author), Zheng, Kedi (author), Zhou, Yangze (author), Palensky, P. (author), Chen, Qixin (author)With the proliferation of distributed energy resources (DERs), electricity consumers in virtual power plants (VPPs) are transitioning into prosumers and are encouraged to share surplus energy with peers. Nevertheless, large-scale energy sharing among thousands of prosumers may encounter communication-related challenges. Communication network...journal article 2023

Wang, N. (author), LIU, Z. (author), Heijnen, P.W. (author), Warnier, Martijn (author)As the use of distributed energy resources increases, peer-to-peer (P2P) energy trading is becoming a promising way to harmonize the decarbonization and decentralization transformations in the energy sector. P2P markets give households the autonomy to make individual decisions and thus they may cooperate with each other to obtain economic...journal article 2022

Rojas-Delgado, Brenda (author), Ekweoba, Chisom (author), Lavidas, G. (author), temiz, Irina (author)This paper proposes and analyzes a genetic algorithm based permutation control logic applied to the aggregator of an offshore multi-source park. The energy losses at the common coupling point are accounted for in the feedback. This paper focuses on offshore distributed energy resources, such as floating photovoltaic (PV), wind, and wave power....journal article 2022

Pelka, S. (author), Chappin, E.J.L. (author), Klobasa, M. (author), De Vries, Laurens (author)Household electricity use has an increasing impact on the overall energy system. Numerous proposals have been made to support households to consume electricity in a system-friendlier manner. By breaking these proposals down into functions and how they are performed, this paper identifies four distinctive governance designs: energy communities,...review 2022

Hennig, R.J. (author), Ribo-Perez, D.G. (author), De Vries, Laurens (author), Tindemans, Simon H. (author)The adoption of distributed energy resources such as PV cells, electric vehicles and batteries in electric grids is increasing steadily. This brings new challenges for distribution networks. The current network tariffs were not designed for these types of usage and, in many cases, they are not adequate anymore. Thus, many new tariff frameworks...journal article 2022

Pelka, S. (author), Kern, Dominik (author), George, Jan (author)Platforms facilitate the participation of households and their energy assets in the energy system. Platform services are considered attractive for households if the energy cost savings exceed the transaction cost of the service. We conceptualize different platform architecture, quantify their transaction cost and compare it to potential energy...conference paper 2022
