Open Data Based Model of the Dutch High-Voltage Power System

A numerical model of a power system can be used to get accurate insights into the impact of policies and investment decisions regarding the transformation of the energy system, while also helping in identifying bottlenecks in implementing decisions. Spatial aggregation, especially for generation and load, must be carefully approached to obtain...

Importance of Model Fidelity of Power to X Devices in Energy System Analysis

Power-to-X (PtX) technologies are accelerating the energy transition. Increasingly, these technologies are also being leveraged as flexible energy resources to support the electrical grid. PtX models are often represented using a constant efficiency term as a linear relation between the power input and energy output. However, the operational...

Optimal Tuning of Active Power Gradient Control for Frequency Support in Multi-Energy Systems

Coping with severe active power imbalances constitutes a challenging task in low inertia multi-energy systems. The phase out of the majority of conventional power plants with large size synchronous generators entails that power electronic interfaced devices should take over the primary task of active power balance-frequency control. In view of...

Technical Assessment of Large Scale PEM Electrolyzers as Flexibility Service Providers

To counter the inherent intermittent and unpre dictable power generation from large amounts of wind and solar, fast-acting resources are required, one of the options being sector coupling via power to gas devices. Industrial Power to Gas (IPtG) resources, such as an electrolyzer, represent an attractive solution to satisfy the rising energy...

Cossembler - Rapid Prototyping Tool for Energy System Co-simulations

Cossembler (co-simulation assembler) is a rapid prototyping tool for co-simulation. The tool is created to expedite the process of co-simulation development for power and energy system studies targeting user groups of power engineers, energy consultants and grid operators. Instead of focusing on message encoding, transportation and...
