The integration of PV systems into diesel grids offers large industries and rural communities a way of saving fuel with a natural and renewable resource. This can be achieved by adding INGECON SUN inverters and Ingeteam's PV-Diesel Controller to the diesel grid.
Challenges of the PV-Diesel hibridization
- To guarantee a minimum load for the gensets, in order to ensure a longer life for the generators.
- To protect against reverse power in case of a total load disconnection.
- To ensure stability against irradiance variations due to cloud shading.
Ingeteam's INGECON SUN PV-Diesel Controller achieves all that and it also monitors the system's power flows and manages the PV power injected to the diesel grid, allowing achieving up to a 70 percent of PV penetration compared to the total diesel capacity.
Ingeteam has developed different solutions for each system type: continuous operation diesel systems (based on one or more gensets operating permanently) or on-demand diesel systems (featuring an external controller that selects the number gensets that will operate depending on the load requirement).
Furthermore, Ingeteam's PV-Diesel Controller allows adding to the system not only a PV installation, but also an energy storage system or even the public grid in order to enable some more advanced configurations. The PV-Diesel Controller will manage all of these elements.
