Learning outcomes
After taken the course student may recognize the most important interconnection principles and technologies of distributed generation (DG) and other distributed energy resources (DERs) like demand side management (DSM) and energy storage. In addition student may explain the main points of network connection technologies from resource and network viewpoints. Student may also analyse and simulate with steady-state simulation tools the interconnection affects of distributed energy resources in electric distribution network planning and operation tasks.
