DESCRIPTION - summary of the module content
AIMS - intentions of the module

The objective of this module is to consolidate and further develop candidates’ core knowledge and understanding of electrical power systems engineering, particularly the issues associated with the connection of renewable energy projects to electricity distribution grids. The overall expected level of attainment is a capability to conduct sensible dialogue with specialist electrical engineers that have been commissioned to complete grid connection studies. Economic, legal and regulatory factors, which influence the design and operation of electricity transmission and distribution networks, are also covered.
