Job description

The research group EELAB / Lemcko is affiliated with Ghent University and located on the UGent campus in Kortrijk. EELAB/Lemcko is specialized in Power Quality, Smart µGrids, Renewable energy, Hosting capacity and Grid Flexibility. You can find more info on www.ugent.be/ea/eemmecs/lemcko/en.

Objective of the research
Photovoltaic Installations (PV), Electric Vehicles (EV), Energy Storage (ES) and Heat Pumps (HP), combined “Stochastic Distribution Grid Exchanges” (SDGE) can result in additional stress on the distribution system due to their fundamentally different behavior from traditional households and building behavior. Due to the increased use of Stochastic Distribution Grid Exchanges (SDGE), the available grid capacity becomes more unpredictable. The grid capacity, further noted as “ampacity” is important to the Distribution System Operator (DSO). Users need to be aware to what extent they can exchange power with the grid under different circumstances, and to which extent they can participate in the energy services and markets. By doing so, we take into account: (i) the impact of decentralized generation, (ii) the integration of storage and (iii) integration of intelligent systems for flexible grid use. The objective of the project can be summarized as the development of innovative concept to avoid hosting capacity problems on distribution grids, taking into maximum grid use, with the goal to improve the performance and reliability.
Jobdescription
Developing a categorical synthetic load profiles including probabilistic load duration curves, in order to develop a definition of the dynamic grid hosting capacity. This must be based on the construction of Categorical Synthetic Load Profiles.
Given the high diversity of the household and appliance stock, customer behavior and lifestyle, as well as number of people per household, it is nearly impossible to determine one generic synthetic load profile that is able to sufficiently model the complex temporal dynamics that are gaining importance for distribution network planning. Consequently, data mining techniques based on (un)supervised machine learning has to be used to generate a set of novel categorical synthetic load profiles (CSLPs) that can (i) distinguish between major types of residential consumers, and (ii) sufficiently capture the diversity in load profile features. For this, several performance indices has to be evaluated to determine suitable categories and representative load profiles per residential user category, making abstraction of the underlying grid and the spatial allocation of individual consumers. However, the LDC does not specify the exact timing of peak demands to occur. Consequently, a forecasting model has to be developed to predict the occurrence of peak demands in the point of common coupling (PCC), leading to the introduction of a stochastic charging capacity that can be dynamically adjusted based on different forecasting models and results.

Research Outcomes/Tasks:

• A set of categorical synthetic load profiles
• Prediction of tolerable number of electrical units for a given feeder model
• Forecasting of dynamic load duration curves of end users and in PCC
  
  

Additional Tasks:

• Project reporting and follow up
• Publish the gathered research results in high ranked journals
• Conduct and follow up of Ma thesis students during their projects related to your research.
• Support the Lemcko staff in teaching and lab sessions.
