Enhanced multi voltage dip ride through for renewable energy power plant with battery storage system

A controller, comprising:

• a memory;
• one or more processors communicatively coupled to the memory and configured to perform an operation to control a renewable energy power plant comprising a plurality of renewable energy generators configured to supply power to an external grid, a plurality of power dissipation systems operable to dissipate power generated by the renewable energy generators, and a battery storage system operable to absorb power generated by the renewable energy generators;
• the operation comprising:
• monitoring the statuses of the power dissipation systems;
• performing a ramped active power recovery operation following a voltage deviation, and
• controlling the battery storage system during the ramped active power recovery operation to absorb power generated by the renewable energy generators in dependence on the monitored statuses of the power dissipation systems.
