Control of local energy systems for enhanced stability and resilience of electrical
Background
Denmark’s transition towards a 100% renewable energy system by 2050 requires new approaches to maintain grid stability, resilience, and power quality in increasingly decentralized energy systems. The growing deployment of renewable energy sources (RES), battery energy storage systems (BESS), flexible loads, and Power-to-X (PtX) technologies creates new opportunities for frequency control, voltage regulation, and ancillary service provision. Industrial parks such as GreenLab demonstrate how PtX-enabled microgrids can support grid operation while contributing to national decarbonization goals. As Denmark targets up to 7 GW of PtX capacity by 2030, coordinated solutions are needed to ensure that local energy systems can provide flexibility services while operating efficiently and reliably.Project
This PhD project investigates advanced Energy Management System (EMS) and coordinated control strategies for clusters of interconnected microgrids, including industrial parks and energy communities integrating RES, BESS, PtX facilities, and flexible demand.The research focuses on maximizing system flexibility and resilience while enabling the provision of frequency and non-frequency ancillary services. Primary ancillary services will be supported through advanced frequency and voltage control methods, including droop control, synthetic inertia, RoCoF-based control, and reactive power support. Secondary and tertiary services will be coordinated through EMS strategies for day-ahead planning and real-time operation.
In addition, the project investigates how local flexibility can be utilized through ancillary-service and local energy markets, ensuring that technical solutions can be deployed in an economically sustainable manner. Market considerations will therefore complement the control and EMS development by assessing how flexibility resources can create value while supporting system operation.
The developed solutions will first be evaluated through simulation studies of single and multi-microgrid systems. Experimental validation will then be conducted using dSPACE-controlled converter platforms, hardware-in-the-loop testing and Speedgoat real-time simulation systems at the Power Electronic Systems Laboratory. The work is closely coordinated with a parallel PhD project at NTNU (Noah Luca Monz), enabling joint investigations of multi-microgrid coordination, control, and flexibility management in future Nordic power systems.
Perspectives
The project will deliver validated frameworks for coordinated EMS and control of multi-microgrid clusters with renewables, energy storage, PtX technologies, and flexible loads. The outcomes will demonstrate how such systems can improve frequency stability, voltage support, resilience, and security of supply while creating value from flexibility services.By combining advanced control, energy management, and practical validation through laboratory and hardware-in-the-loop experiments, the research will support the integration of local energy systems into future power networks. The DTU–NTNU alliance further strengthens the development of scalable solutions for Nordic energy systems, contributing to a reliable, flexible, and economically sustainable green transition.
