A microgrid is an intelligently controlled energy system designed for local power generation including traditional and renewable sources, energy storage, and distribution. It is engineered to operate reliably both when connected to the utility grid if available and as a fully independent isolated system.
By combining renewable generation, battery energy storage systems, and diesel or gas backup generators, a microgrid provides a stable power supply in remote communities, industrial facilities, or critical infrastructure where operational continuity is essential. Customers gain energy independence, improved cost control, and increased resilience against grid outages.
We design and implement microgrid control logic that automatically responds to changes in generation, load, and grid conditions. Our goal is to ensure stable, safe, and predictable system behavior, even under demanding operating conditions.
Each generation or storage unit within the microgrid is equipped with its own PLC controller responsible for safe and autonomous operation. We develop control logic that ensures both proper standalone functionality of each unit and its seamless integration into the overall system.
Our solutions include:
We design control strategies that balance active and reactive power across all units in the microgrid in real time. The system continuously considers resource availability as well as the technical limitations of individual assets.
Control logic accounts for:
This ensures a stable, efficient microgrid capable of responding to rapid load changes.
We design diesel generator control in a way that generators operate only when truly required. The system continuously evaluates the current state of generation and energy storage and optimizes generator start/stop decisions.
The logic considers:
The solution also includes controlled transitions to generator-free operation, where the system runs solely on batteries and renewable energy sources.
When available power is insufficient to supply all loads, we implement controlled load shedding strategies based on predefined load priorities.
This approach protects critical technologies and ensures controlled system operation, even in emergency scenarios.
In the event of a complete power outage, we design and implement automated recovery sequences that enable a safe and gradual restart of the entire microgrid without the need for manual intervention.
The microgrid can actively support grid stability by regulating the injection or absorption of active and reactive power at the point of connection. System behavior parameters can be customized to meet local grid requirements.
We control active and reactive power flows to:
This directly results in lower operating costs and increased system stability.
Smooth and safe connection of a microgrid to the utility grid requires appropriate synchronization protection and measurement devices that meet synchronization requirements (voltage, frequency, and phase angle). When these conditions are met, we provide automatic synchronization with the grid without any impact on system operation.
Where technology allows, we implement seamless transitions to islanded operation, during which the inverter assumes the grid-forming role and the system continues operating without any interruption of power supply.
