The invention discloses an energy conversion layered optimization
control system and method for a wave energy power generation device. The
system employs a three-layer
system architecture, a layered
control layer receives an
electric energy dispatching instruction of an island
microgrid, manages a function
control layer, and also transmits the real-time operation condition of the wave energy powergeneration device to a
monitoring system of the island
microgrid, the function
control layer receives a control instruction of the layered control layer and manages a function implementation layer ina unified mode, the function implementation layer comprises a wave energy capture
system control unit, a hydraulic energy conversion system
control unit and an
electric energy conversion system
control unit, power matching and operation optimization among the wave energy capture system, the hydraulic energy conversion system and the
electric energy conversion system are realized, and the efficiency and
controllability of the wave energy, the hydraulic energy and an electric energy multistage energy conversion system of the wave energy power generation device are improved, so that the
controllability and stability of electric energy output of the wave energy power generation device are improved, and grid-connected coordinated operation of the wave energy power generation device from the island
microgrid is facilitated.
