Optimal planning of electrolyzers in distribution grids as a solution to grid congestion? A real-world case study in the Netherlands

Rik Koenen, Thomas Swarts, Johan Morren

This study proposes a mixed-integer second-order cone optimization model for the cost-optimal siting, sizing, and operation of electrolyzers in integrated hydrogen and medium-voltage electricity networks, including cost-optimal network expansion. Unlike studies based on standardized IEEE test cases, the model is applied to …

A Planning Framework for Power-to-Gas in Multi-Energy Distribution Systems

Thomas Swarts, Johan Morren, Wouter van den Akker, Arjan van Voorden et autres

Power-to-gas (P2G) systems can provide multifaceted services within Multi-Energy Systems (MES) beyond traditional roles. When strategically deployed, P2G systems can mitigate congestion in the electricity grid, advance the heat transition through the utilization of their waste heat, and optimize the usage of …

Mitigating Increase-Decrease Gaming with Alternative Connection Agreements: A Defender-Attacker-Defender Game

B. van der Holst, Thomas Swarts, Phuong Vu Nguyen, Johan Morren et autres

Redispatch markets are widely used by system operators to manage network congestion. A well-known drawback, however, is that Flexibility Service Providers (FSPs) may strategically adjust their baselines in anticipation of redispatch actions, thereby aggravating congestion and raising system costs. To address this …

Contracting Strategies for Electrolyzers to Secure Grid Connection: The Dutch Case

Thomas Swarts, Jalal Kazempour, Wouter Van Den Akker, Johan Morren et autres

In response to increasing grid congestion in the Netherlands, non-firm connection and transport agreements (CTAs) and capacity restriction contracts (CRCs) have been introduced, allowing consumer curtailment in exchange for grid tariff discounts or per-MW compensations. This study examines the interaction between an …

Flexibility of Distributed Power-to-Gas in Interconnected Electricity-Gas Distribution Network Including Pressure Management

Thomas Swarts, Johan Morren, Wouter Van Den Akker, J.G. Slootweg et autres

This study investigates the impact of pressure limits in natural gas (NG) distribution networks on the economic effectiveness of Power-to-Gas (P2G) systems in alleviating congestion and associated reinforcement investments in electricity distribution networks. A joint optimal planning and operational model integrating P2G …

Power-to-gas: value-stacking by waste-heat utilization and curtailment prevention

Thomas Swarts, Johan Morren, Wouter Van Den Akker, J.G. Slootweg et autres

This study proposes a MILP model that optimally sizes and dispatches P2G systems to minimize their levelized costs of hydrogen (LCOH). The study quantifies the effect of additional revenue streams on P2G systems’ LCOH, namely revenue from selling the systems’ waste-heat, and …

Techno-economic analysis of low-temperature electrolysis' waste-heat utilization

Thomas Swarts, Johan Morren, Wouter van den Akker, J.G. Slootweg et autres

Low temperature electrolysis will be an indispens-able system integration asset in future low-carbon energy systems but is known for its inefficiency and associated waste-heat production. Low temperature electrolysis' waste-heat could be used in e.g. 4th or 5th generation district heating systems. However, …
