PhD in Advanced Informatics for Distributed Grid Balancing Through Flexibility Aggregation
About the job
This PhD position is connected to the FME Norwegian Centre for Energy Transition Strategies (NTRANS), which is a multidisciplinary national research centre studying transitions in the energy sector and related sectors. The FME NTRANS is a collaboration between 8 Norwegian research institutions and over 30 user partners from the industry and the public sector. Key research areas are the future energy system, active consumers and distributed solutions, deep decarbonisation and sector couplings, and accelerating the energy transition. The position is linked to Research Area 3 “Future Energy Systems” within FME NTRANS.
The rapid proliferation of intermittent renewable energy sources in grid increases the need for more flexible loads to act as reserves for grid balancing. Recently, the idea of aggregating flexible loads from residential sector as an inexpensive reserve source has gained prominence. The flexibility offered by these loads needs to be activated automatically using modern ICT systems without affecting end-user’s comfort. To activate and manage these loads in real time, their flexibility needs to be estimated first and then optimally scheduled. This requires monitoring current appliance status, its energy demand and forecasting future consumption. Installing smart plugs or temperature sensors to monitor power consumption characteristics of each flexibility source is expensive. Hence, there is a need to develop alternative cost-effective techniques for estimating flexibility of heat pumps using informatics-based approaches.
The success of future power systems largely depends on the ability of the grid to identify, activate, harness, and exploit the distributed flexibility potential offered by small-, medium- and large- scale producers/ consumers/prosumers and aggregators. Recently, there has been huge interest in providing flexibility services from distributed resources such as heat pumps to transmission grid operators through aggregated and automated demand response, especially for frequency reserves in the Nordic balancing markets.
In this context, the main task of the PhD candidate in the doctoral work will be two-fold. First, to develop machine learning based grey box models for capturing relationship between power and temperature in heat pumps to accurately estimate and maximally extract flexibility. Second to develop operational scheduling strategies for aggregated demand response of distributed heat pumps to cater to stringent technical requirements of balancing markets.
The main supervisor for the PhD position is Associate Professor Jayaprakash Rajasekharan.
Your immediate leader is head of the department
Duties of the position
The objective of the PhD education is to qualify for scientific research of high international standard. The PhD education has a nominal duration of three years of full-time study and includes required coursework or similar academic training comprising a minimum of 30 credits. The most important component of the PhD education is an independent scientific research project carried out under academic supervision, which results in the PhD thesis. The PhD degree is conferred based on these two elements and the doctoral examination, which consists of a trial lecture and a public defense of the scientific thesis.
- combining knowledge from optimization, operations research, big data and informatics to develop dynamic resource allocation methods for Nordic balancing markets through aggregated demand response from distributed resources
- reviewing existing state-of-the-art literature and collecting data
- conducting high quality research and report progress on a regular basis and in agreement with the supervisors.
