Do you want to be part of an industry-oriented project and work on flexibility estimation from industrial sites?The envisioned research is part of the research program Intelligent Energy Systems (IES) performed within the Electrical Energy Systems (EES) group of TU/e. Within the IES program, research is conducted into operation and planning of future sustainable energy systems, with an emphasis on electricity systems, markets and systems integration. This research is performed in two research labs: the Digital power and energy systems lab (EES DigiPES lab) and the Electricity markets and power system optimization lab (EES EMPDO lab). The former focuses on intelligent energy network research, including: demand management and flexibility, digital twinning, data analytics, smart grid ICT architectures and systems integration in multi energy systems. The latter specializes in electricity market design (centralized & decentralized), market products & system services to integrate new technologies, forecasting, market participation strategies and risk management, large-scale, distributed, multi-objective optimization techniques applied to energy markets and power systems and AI for optimization and control in power and energy systems. The EES group has strong ties with industry both nationally and internationally, with several part-time industry researchers working in the group and a large group of strategic collaboration partners.
Recently, the Electrical Energy Systems group received grants for nationally-funded projects in Intelligent Electricity Systems. Therefore, this group currently has multiple vacancies in this field.
We are currently looking for researchers with strong energy systems knowledge, electricity, heat, and gas system components and flexibility modelling & simulation, and research software development skills that want to develop cutting-edge knowledge and software for the
energy transition. The focus of the work will be on the application of intelligent software approaches (distributed control systems, distributed optimization, market mechanisms, multi-scale modelling, etc.), in electrical power systems (energy system flexibility coordination, local energy markets, capacity & congestion management, etc.).
InformationThe decarbonization of the industrial sector is critical to achieving climate neutrality. Steam-based industries, such as chemical manufacturing, food processing, and paper production, are among the most energy-intensive and carbon-emitting sectors. Electrification of thermal processes, particularly through the integration of industrial heat pumps, presents a promising pathway to reduce emissions while offering flexibility services to the energy system.
At the same time, the increasing penetration of variable renewable energy such as wind and solar creates a pressing need for
flexibility services to balance supply and demand. Industrial processes, with their significant thermal inertia and storage potential, can provide valuable flexibility to the power grid. However, the integration of such services into
steam-heated industrial processes remains a challenge, especially when considering the role of
large-scale heat pumps, industrial heat storage, and heat recovery technologies as both decarbonization and flexibility enablers. The challenge rises from several factors affecting the daily operation of the factories as well as the investment requirements that might not be compensated accordingly when the derived flexibility is offered to the grid/market. In this regard, this PhD focuses on optimizing the use of flexibility in electrified process plants by leveraging dynamic behaviors and market participation.
With the above premises, the main objectives of this study are
- Characterize the thermal demand profiles of steam-based industrial processes and identify opportunities for electrification. => Baseline optimisation
- Assess the technical feasibility and performance of industrial heat pumps in steam generation and recovery. => Design options and technology inclusions
- Develop models to quantify the flexibility potential of electrified steam systems, including load shifting, demand response, and ancillary services. => Energy use optimisation
- Assess the techno-economic feasibility of providing flexibility services from electrified steam processes. => Business assessment
- Grid impact assessment and capacity management approaches in an industry-infused network with integrated industrial flexibility services. => Grid impact assessment
In order to achieve these goals, the following tasks would shape the work plan of the PhD:
Energy Portfolio Creation: A comprehensive estimation of the available flexibility within electrified process plants should be undertaken. This task involves a detailed assessment of the various processes and identifying potential extractable flexibility from electrified thermal systems. The goal is to quantify the extent to which these processes can be adjusted or modulated, taking into account the operational constraints and requirements. This estimation will include analyzing the energy consumption patterns, identifying peak and off-peak periods, and understanding the critical operational parameters that must remain stable. The maximum achievable flexibility that can be harnessed without compromising the efficiency, productivity, and overall operational stability of the process plants can be determined. This rigorous analysis will provide a clear picture of the flexibility potential and set the stage for implementing effective flexibility services tailored to the dynamic behavior of the process industry.
Flexibility service definition and potential calculations: The next task would be to identify and define flexibility services that are specifically tailored to the dynamic nature of process industries. This involves a thorough examination of the various industrial processes to determine how they can be adapted or modulated to provide flexibility services. The approach includes a detailed analysis of the operational characteristics and requirements of each process, aiming to understand the inherent dynamic behaviors and how they can be leveraged to create flexibility.
Through exploring different strategies for modulating processes, such as adjusting production schedules, varying energy consumption rates, and implementing advanced control systems, new definitions for flexibility services from industry will be provided. This definition would consider the type, feature, and characteristics of the service from both industry side and market side, meaning the conditions that the plant needs to follow to provide such services as well as the market conditions to which the service is offered.
Evaluating implementation potential: In this task,
the energy market status for the process industry will be analysed to determine the viability of electrified processes considering the increased required electric demand and the new possibilities of saving energy costs using the flexibility of electrified thermal systems. To achieve this, the current status of the markets will be analysed to assess the possibility of incorporating industrial flexibility. Different revenue schemes will be considered to deploy industrial flexibility as a product in the market. The flexibility trade with the characteristics of flexibility from industrial processes will be analysed. The energy market status for both electricity and gas markets will be studied to evaluate the viability of electrification for specific cases and in regard to price growth of electricity and gas. The trade portfolio of an electrified industrial site will be provided with possibilities of energy market participation, flexibility services remuneration, and CO2 to capture revenues.
This PhD is part of a NWO project called “Flexibility in Electric Power from Steam-heated Industrial Processes” (FLEXPower). There are several partners involved in this project including a large distribution system operator, industrial partners, industrial flexibility technology providers, and an applied research institute. The PhD student will be involved in this project, will have the chance to participate in meetings, and have a close collaboration with industry. The study could also benefit from using real data from the industrial partners involved in the project.
