pre374 - Power Grid Analysis and Studies (Complete module description)

By the end of this module students should be able to acquire relevant data to evaluate grid power quality, to model permanent and dynamic transient regimes of electric grid elements and to plan and optimise grid design.
Specifically, the student will
- be able to perform different studies (permanent, dynamic or transitional regimes) to undertake in electric grids to ensure correct planning and operation
- get basic knowledge on grid modelling (static and dynamic)
- be able to perform stability studies
- get to know different aspects about power supply quality
- be able to perform an optimal sizing of renewable energies installations
Engineering analysis:
Graduates will be able to formulate and solve engineering problems related to Power Supply Quality.
Investigations:
Graduates will be able to acquire relevant data to evaluate grid power quality.
Engineering design:
Graduates will be able to model permanent and dynamic transient regimes of electric grid elements, also to plan and optimise grid design.
Transferable skills:
Graduates will be able to work effectively as a professional and as team member in the resolution of technical problems related to integration of RE in electric grids. Also, graduates will demonstrate their abilities to communicate effectively in multinational groups.
