About the position

The Department of Energy and Process Engineering is seeking a PhD Candidate in Performance Analysis of the Combined Solar and Heat Pump Systems. The position is part of the research project “Key technologies and demonstration of combined cooling, heating and power generation for low-carbon neighbourhoods/buildings with clean energy ChiNoZEN” jointly funded by the Ministry of Science and Technology (MOST) in China and the Research Council of Norway (RCN). This announcement relates to position funded by RCN and will be hired by NTNU.

The Norwegian part of the project is linked to the four Research Centres on Environment-friendly Energy (FME Centres): FME ZEN, FME HighEFF, FME SuSolTech and FME Cineldi, hosted by NTNU, SINTEF Community, SINTEF Energy Research, and Institute for Energy Technology (IFE). The Chinese consortium comprises prominent universities and industry partners: Beijing Jiaotong University, China Academy of Building Research, Gree Electric Appliances, Inc. of Zhuhai, Solareast Holdings Co. Ltd., Lanzhou University of Technology, North China Electric Power University (NCEPU), Qingdao Somir Energy Science and Technology Co. Ltd., Shanghai Jiao Tong University, Tsinghua University, Xi’an University of Architecture and Technology.

The commitment of the ChiNoZEN project is to contribute to a significant increase in the share of low-carbon buildings and neighbourhoods through research cooperation between leading Chinese and Norwegian scientists.

The ChiNoZEN project supports the transition to a reliable, affordable, publicly accepted, sustainable built environment, aiming at reducing fossil fuel dependency in the face of increasingly scarce resources, growing energy needs, and threatening climate change. The project delivers new knowledge, solutions and innovative technologies for low-carbon buildings and neighbourhoods.

The research is carried out in five work packages (WPs): WP1 Performance of grid-connected photovoltaic technologies (PVT) with Thermal Energy Storage (TES), WP2 High temperature heat pump (HTHP) and dynamic performance, WP3 Simulation platform and control strategy of CCHP, WP4 Key CCHP technologies of low carbon neighbourhood and buildings with multiple energy sources, and WP5 Demonstration of low carbon neighbourhood and buildings with clean energy.

The Norwegian part of the ChiNoZEN project is managed by FME ZEN and hosted by the Faculty of Engineering, Norwegian University of Science and Technology – NTNU.

Two PhD and four postdoctoral fellow positions for the Norwegian part of the ChiNoZEN project are located in various departments at NTNU and IFE, ensuring the cross-disciplinary research needed in order to reach the aim of the project. All PhD and postdoctoral fellows will stay minimum six months with one of the partners in China.

The Head of Department is Professor Terese Løvås. The day-to-day position management and supervision is by Associate Professor Laurent Georges.

Duties of the position

We are looking for a PhD candidate related to WP1 Performance of grid-connected photovoltaic technologies (PVT) with Thermal Energy Storage (TES) for the topic: Performance Analysis of the Combined Solar and Heat Pump Systems (WP1 PhD Fellowship from Sep 2020 to Aug 2023)

Objective:

Distributed Photovoltaic Thermal Hybrid solar systems (hybrid PV/T) generate heat and electricity based on a same component. Using most common PV/T, water is heated by the collector and simultaneously cools down the solar cells so that the PV generation efficiency is increased compared to a stand-alone PV system. This supposes that the water is heated at a moderate temperature level to keep the PV efficiency high, a temperature level that is not useful for many building applications. To reach higher temperatures (in the range of 90°C) with high efficiency, a heat pump (HP) system driven by the PV/T electricity is coupled to the grid-connected system.

In this research work, different PV/T technologies, heat pump and thermal energy storage (TES) will be compared. The performance will be studied using dynamic simulations where both the design (e.g. temperature levels and components sizes) and the overall system control will be optimized. Two main performance indicators are the energy efficiency and the peak-shaving potential. The performance of conventional controls will be compared to predictive controls where short-term forecast will be taken into account (i.e. time-varying electricity prices, temperature and solar irradiation).

Research questions:

  • Determine the best components (PV/T, HP and TES) to form the system
  • Define the optimal design of this system (e.g. sizing and system layout)
  • Develop predictive controls to maximize energy efficiency and peak shaving
  • Compare the overall system performance with other standard heating strategies

Selection criteria

Essential qualifications

  • The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is a completed Master’s degree or second degree (equivalent to 120 credits) with a strong academic background in thermal and energy systems engineering or equivalent education with a grade of B or better in accordance with NTNU’s grading scale. Applicants with no letter grades from previous studies must have an equally good academic foundation. Applicants who are unable to meet these criteria may be considered only if they can document that they are particularly suitable candidates for education leading to a PhD degree
  • The candidate should have excellent communication skills in English (oral and written)
  • Candidates should be able to work in an inter-disciplinary environment
  • The applicant must enclose a research project description (max. 3 pages incl. references) indicating his/her view of the main research challenges in the area of the position, how they suggest to do the research work and how this is relevant for their own background and the above research objectives and questions

Desirable qualifications

  • Research or professional experience in one or several of the following domains will be highly appreciated: solar and heat pump systems, analysis of thermal systems using dynamic simulations (typically TRNSYS or Modelica), optimal control or model predictive control (typically using linear or quadratic programming), data pre- and post-processing in tools like Python or MATLAB
  • Knowledge of the Norwegian language will be considered as an advantage
  • Candidates experienced with international cooperation, particularly with China, would be preferred

Personal characteristics

  • Confidence in working independently
  • Ability and willingness to work in inter- and transdisciplinary teams
  • Creativity
  • Critical thinking
  • Excellent communication skills

In the evaluation of which candidate is best qualified, emphasis will be placed on education, experience and personal suitability.
