The utility-scale co-located hybrid power plants (HPPs) have been receiving attention globally due to enhanced controllability and efficient utilization of electrical infrastructure. While plant control has extensively studied for single-technology in the past decades, how a HPP that includes sub-plants with multiple technologies is yet be well defined. To fill gap, this paper proposes novel hierarchical architecture HPPs. This contains four levels: asset level, level energy management system (EMS) level. objective EMS find optimal strategies market participation, execute those from real time. interactions across hierarchy are firstly discussed paper, where closely paid between Novel coordination presented ensure all levels work together without counteracting against each other. Frequency fault ride-through two examples demonstrate such coordination.
