Hierarchical control architecture of co-located hybrid power plants

Utility-scale co-located hybrid power plants (HPPs) have received global attention due to enhanced controllability and efficient utilization of electrical infrastructure. While control mono-technology has been extensively studied over the past decades, HPP including sub-plants multiple technologies is yet be addressed. This paper fills such gap by proposing a novel hierarchical architecture for HPPs. Said contains four levels: asset level, plant level energy management system (EMS). The objective EMS generate optimal bidding strategies market participation, while execute real-time dispatch plans achieving expected targets regarding active energy. Attention paid interactions across different levels hierarchy, particularly between with level. Novel coordination are presented ensure all work together without counteracting against each other. Frequency fault ride-through employed as examples demonstrate coordination. • Design plants. Definition exchange variables hierarchy. Development controller relevant functions.
