Project Description
The electrical power supply systems of the future will be characterised by a high proportion of renewable energy sources, by decentralised, externally determined generation and frequently by a strongly developed electricity business. This particular integration of distributed renewable generation sources into the electricity grid poses a number of challenges for the industry. Utilities will be faced with issues of enabling high penetration of wind power into both existing and future distribution networks.
The main focus of this PhD project is to investigate the influence of renewable energies and distributed power production on the operation of active distribution networks, based on the advanced real-time digital simulation platform. The basic challenges of making accurate simulations of small coupled systems will be addressed.
Over three phases, the goal of this project is to develop a flexible digital simulation platform for the modelling, control/operation and verification of a typical Danish distribution network that incorporates several renewable energy sources combined with conventional power production plants.
The simulator needs to be capable of representing the dynamics of three phase networks for simulating operations of specific technologies/models, and for the verification of proper operations along with special emphasis on islanding operation as well as different interface methods to realize power hardware in the loop (HIL) simulations. Based on these real-time models and studies, power system operation problems are identified faster, operating schemes and technical solutions are designed and tested.
