Energy Flexibility Analysis using FMUWorld

Abstract

Energy flexibility is key to integrating more renewables into the grid. An essential contributor to enabling energy flexibility is P2X technologies such a Power2Heat, Power2Gas, among others. To evaluate the flexibility available from these resources and the impact they can have on the electrical grid, complex simulations need to be set up that may not always be possible using traditional simulation tools, given the multi-domain nature of such systems. Hence, the need for intelligent simulation techniques arises. This paper introduces a co-simulation tool, FMUWorld, to overcome simulation problems for complex energy systems. We use a multi-energy co-simulation and an energy flexibility analysis as use cases to explore the capabilities of the proposed tool. The ease-of-use offered by FMUWorld is shown to allow users to focus more on analysis of the system, such as parameter sensitivity, system optimisation, etc., rather than co-simulation setup. The paper highlights the key features and functionalities of FMUWorld that make it a novel tool for cosimulation of multi-energy systems.

Technical Assessment of Large Scale PEM Electrolyzers as Flexibility Service Providers

“…Since the electrolyzer and the grid are modeled in different programs and operate in different ways (electrolyzer system is a dynamic continuoustime model, while the electrical grid is a static-time power flow model), we use co-simulation based methodology for analysis. The co-simulation tool used is ENERGYSIM, (previously FMUWORLD) [16]. The choice is motivated by the fact that this co-simulation tool is tailor-made for multi-energy system studies.…”
