Stochastic Energy Source Access Management (SESAM)

Project Summary

Full Title: Stochastic Energy Source Access Management (SESAM): Infrastructure-integrative modular plant for hydrogen-electric co-generation
Project ID: 140
Principal Investigator: Kai Strunz

Purpose

The model demonstrates a renewable power plant that is designed to seamlessly integrate with the given energy infrastructure while serving the dual purpose of generating electric power and hydrogen. A multilevel storage absorbs short-term shocks on the infrastructure while also compensating for intermittency of wind and solar energy conversion in the long term. The model supports in particular analysis and design of a hydrogen infrastructure with a high penetration of renewable energy.

Project Description

Type of Project: Model
Category: Energy Infrastructure, Hydrogen Fuel Pathways
Objectives: Integration of renewable and hydrogen energy; control of renewable hydrogen-electric co-generation plants; network interface for renewable hydrogen-electric co-generation plants; transient behavior of renewable hydrogen-electric co-generation plants; design of multilevel storage for multiscale compensation.
Technologies Modeled: Wind energy conversion; fuel cell; electrolyzer; access-oriented storage (short-term storage); power electronic converters, control systems.
User Inputs: Renewable power; scheduled exchange of hydrogen with hydrogen infrastructure; scheduled exchange of electric power with electricity infrastructure; profile of local loads; initial conditions of storage.
Methodology/Approach: Block-diagram description; fuel cell modeling; electrolyzer modeling; storage modeling; wind energy conversion system modeling; power electronic converter modeling; electric network modeling; control system modeling; modeling of transients.
Hardware/Software Requirements: Models run on off-the-shelf PCs with software MATLAB/Simulink installed.
User Interface: The models are implemented in MATLAB/Simulink and make use of the interface provided by MATLAB/Simulink.
Outputs: Wind power; filling of energy storage; filling of hydrogen storage; power exchange with electricity infrastructure; power exchange with hydrogen infrastructure; diverse quantities pertaining to electrochemical conversion and power electronic conversion; control signals
Assumptions Inherent in Model: Power electronic converters represented as average models; fuel cell and electrolyzers can be represented at a level of accuracy necessary depending on whether short-term or long-term transients are considered.
Timeframe Studied: 2005 - 2020
