Hybrid GPM PPC

The Hybrid GPM PPC can control both photovoltaic (PV) plants and battery energy storage systems (BESS) in real time. In contrast with single technology renewable plants which produce their power from only one centrally controlled power source, hybrid sites introduce increased complexity.

The different nature of the power provided by PV plants is strictly one-directional. When combined with the storage flexibility of the BESS, it allows for a large number of possible services and requirements. In this way, the hybrid GPM PPC architecture includes all the available control modes, enabling it to meet the requirements imposed by the TSOs, while managing the required active power at the POI by distributing it between the PV plant and the BESS.

The hybrid GPM PPC adds an additional control architecture which distributes the power setpoint of the GPM PPC between the BESS and the PV inverters, while allowing site operators to choose between different control modes and functionalities. These hybrid control modes provide increased flexibility to the operation of the power plant, and allow the user to manage the power output of the BESS following different criteria.
