What Is a PPC? Hybrid, Master and Slave Control Roles
Understand power plant controllers in wind, solar, hydro, biomass and storage projects, including master and slave roles.

A PPC coordinates generation, storage and power control. Enlogy PPC can operate in hybrid, master or slave roles across multi-source and storage projects.
Master PPC role
In a master configuration, the PPC coordinates control points and evaluates instructions from supervisory systems within a defined control flow.
Slave PPC role
In a slave configuration, another system retains the higher-level control authority. The PPC exchanges data, status and commands with that architecture.
Hybrid and storage scenarios
Wind-plus-solar, biomass-plus-solar, solar-plus-solar and hydro-plus-solar plants can coordinate sources and storage through shared control logic.
Questions and answers
Should a PPC be master or slave?
The design depends on existing SCADA, field controllers, grid requirements and project responsibilities.
Which protocols does the PPC support?
Select protocol interfaces and control functions to match equipment, grid interfaces and the defined project configuration.
