Postdoc in Synthetic Inertia Provision of Battery Energy Storage

Postdoc in Synthetic Inertia Provision of Battery Energy Storage

Join us in developing zero-emission synthetic inertia with BESS to stabilize the future grid and shape the next generation of resilient, sustainable energy systems.

Job description

The accelerating transition from fossil fuels to renewable energy is significantly reducing system inertia on the electricity grid, traditionally supplied by synchronous generators. This loss of inertia is leading to increased grid instability and a growing number of frequency-related failures. Maintaining sufficient inertia is critical for the secure and resilient operation of the power system.

Battery Energy Storage Systems (BESS), when equipped with advanced control algorithms, offer the potential to provide synthetic inertia—mimicking the inertial response of conventional power plants. This approach delivers grid support with zero emissions and low maintenance costs, aligning with decarbonization goals. At the same time, synthetic inertia provision is becoming a monetizable service in an increasing number of electricity markets, presenting new business opportunities for BESS operators.

This postdoctoral position will focus on both technical and economic challenges associated with synthetic inertia from BESS, including but not limited to:

• Accurate quantification of synthetic inertia and system response.
• Modeling and optimization of battery control strategies for inertia provision.
• Assessment of battery degradation and lifecycle costs attributable to synthetic inertia services.
• Integration of synthetic inertia into market mechanisms and grid codes.

The successful candidate will work as part of the BATT-AI project, collaborating with two PhD researchers focused respectively on optimal electricity market participation of BESS and grid congestion management facilitated by BESS.

The postdoc is expected to take a leadership role in research integration and coordination within the project and contribute to joint publications, system modeling, and stakeholder engagement. The project is strongly supported by industry, with collaboration from: Alfen – BESS developer, Stedin – grid operator, Eneco – energy supplier, ENTRNCE – electricity market expertise provider, Kyos – developer of market optimization tools.

This position offers a unique opportunity to conduct high-impact research at the interface of power systems, converter control, battery degradation, and market economics, with direct pathways to real-world application and policy influence.

About the department

The research in ESE Department is inspired by the technical, scientific, and societal challenges originating from the transition towards a more sustainable society and focuses on four areas:

• DC Systems, Energy Conversion and Storage (DCE&S)
• Photovoltaic Materials and Devices (PVMD)
• Intelligent Electrical Power Grids (IEPG)
• High Voltage Technologies (HVT)

ESE Department owns the ESP laboratory is actively used for testing of grid integration of power electronics, battery degradation, hardware in loop simultion (HIL), AC and DC protection, and wide-area monitoring, protection and control.

The DCE&S group is responsible for research and education in the fields of DC systems, energy storage, electronic power conversion (power electronics), electro-mechanics for electric mobility and recently electro-chemical conversion. DC systems is a multidisciplinary field of research, exploring the electronic power conversion of electrical energy for different applications. The group is currently active in applications such as Direct Current distribution grids and microgrids, electrification of mobility (charging of electric vehicles), and renewable generation of electrical energy (such as wind and solar energy) as well as sustainable production of chemicals and fuels through large-scale conversion of renewable electricity into molecular bonds

Faculty Electrical Engineering, Mathematics and Computer Science

The Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) brings together three scientific disciplines. Combined, they reinforce each other and are the driving force behind the technology we all use in our daily lives. Technology such as the electricity grid, which our faculty is helping to make completely sustainable and future-proof. At the same time, we are developing the chips and sensors of the future, whilst also setting the foundations for the software technologies to run on this new generation of equipment – which of course includes AI. Meanwhile we are pushing the limits of applied mathematics, for example mapping out disease processes using single cell data, and using mathematics to simulate gigantic ash plumes after a volcanic eruption. In other words: there is plenty of room at the faculty for ground-breaking research. We educate innovative engineers and have excellent labs and facilities that underline our strong international position. In total, more than 1000 employees and 4,000 students work and study in this innovative environment.

Conditions of employment

• Duration of contract is 1 year with prospect of extension of 18 months.
• A job of 36-40 hours per week.

Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities. The TU Delft offers a customisable compensation package, discounts on health insurance, and a monthly work costs contribution. Flexible work schedules can be arranged.

You will benefit from extensive training in technical and transferrable skills. You will be expected to assist in teaching activities (student supervision, labs) related to your subject area.

You will have access to excellent research facilities in ESP lab
