PhD Project: Hosting Capacity for Solar Power in Northern Sweden

Introduction:

This project is about the impact of large amounts of solar power on the electricity grid. The base of the project will be to determine how much solar power can be connected before the grid and / or other customers are affected in an unacceptable way; the so-called "hosting capacity".

The concept of hosting capacity was first introduced in 2004 and part of the common terminology in both research and with network companies and regulators. New mathematical models will be developed to include different types of uncertainty in the calculation of the hosting capacity. Case studies will be carried out, during which these methods are applied to existing electricity grids in northern Sweden. The project includes, among other things, how the developments on the consumption side (like data centres and electric cars) and new technological developments on the production side (like battery storage) affect the hosting capacity.

The project is being undertaken by me (Enock Mulenga), Math Bollen, Sarah Rönnberg and an added industrial input/supervision of Nicholas Etherden of Vattenfall AB- R & D department.
