A utility-scale hybrid renewable energy plant combines 100 MW solar PV, 100 MW wind, and 30 MW pumped hydro storage to supply firm power to the grid. The pumped hydro operates as a load when pumping and a generator when releasing water, enabling energy shifting and grid stability.
Read the decisions behind it.
Modeled pumped hydro as separate generator and load nodes on the same bus to represent bidirectional flow without a dedicated storage symbol
Used ANSI/IEC-neutral device symbols with standard breakers and transformers
Included separate breakers for each generation and load feeder for protection coordination
Selected 34.5 kV collector bus voltage and 138 kV grid interconnection to match typical utility-scale practice
Use this design when planning or documenting the electrical infrastructure of a hybrid renewable energy facility that includes dispatchable storage and requires clear representation of power flow directions for protection and control studies.
