Success cases

Solar integration and thermal generation coordinated through intelligent control

In Pilar, province of Córdoba, an agricultural facility operates a pivot irrigation system in an environment without access to the electrical grid. The continuity of the process depends exclusively on autonomous generation, composed of a 200 kVA diesel generator set and a photovoltaic solar plant with a GoodWe 80K-MT inverter.
The objective of the project was to reduce the generator’s fuel consumption by leveraging available solar energy, without compromising the electrical stability of the system. In off-grid applications, solar inverters require a firm voltage and frequency reference, which must be provided by the generator. This prevents their complete disconnection, even when irradiation is high.
Servintel designed and implemented a solution based on Hybrid Control 1000, enabling the integration of both sources without modifying existing equipment or performing a retrofit. The architecture established the generator set as the permanent reference of the microgrid, while solar generation dynamically adjusts according to demand and irradiation.

Under optimal conditions, the generator operates close to its recommended technical minimum, ensuring stable combustion and reducing consumption. In the event of load variations or reduced solar input, the system automatically increases thermal contribution to maintain electrical quality.

The solution made it possible to optimize fuel usage, maximize renewable contribution, and guarantee operational stability, establishing an efficient hybrid architecture prepared for future expansions.
