BELECTRIC Hybrid Controller
High penetration of renewable energy requires an intelligent control system to keep the different energy sources in
balance. As the operator of a hybrid system, you will demand both grid stability and a cost-optimized system operation. And you are right to do so! The BELECTRIC Hybrid Controller focuses on these requirements and ensures
four key criteria:
Voltage

Reliability
Frequency
Stability

Features: Voltage Quality
Voltage fluctuations can cause severe problems for many consumers in a power grid. Whenever a voltage deviation
occurs, the BELECTRIC Hybrid Controller ensures the supply of reactive power via the different energy sources in
order to minimize such voltage deviations. With the right choice of inverters for your solar power plant, this can
even be done at night when the sun is not shining!

Features: Frequency Quality
You will want your grid to run at a stable frequency. The BELECTRIC Hybrid Controller uses a multiple approach
to ensure this. By allocating the required resources of conventional rotating engines and inverters with virtual
inertia, by smartly distributing primary control reserves between all connected units, and by cyclic adaptation of
all necessary power set points, the Hybrid Controller handles all kinds of dynamic load variations to be expected in
your grid. This keeps the grid frequency as stable as you want it to be!

Features: Supply Reliability
The BELECTRIC Hybrid Controller guarantees a stable energy supply 24 hours a day and 7 days a week. It takes
the potential fluctuations of renewable energy sources and possible outage of generators into account and smartly
allocates the energy sources accordingly, thereby ensuring that your power will never go off!
è Stable power supply 24/7
Features: Cost Optimization
The BELECTRIC Hybrid Controller does more than just grid stabilization:
By considering the individual characteristics of each generating unit, the
current power demand, the specific generation costs and availability of
the different power sources, the controller ensures the power mix with
the lowest specific cost at all times. Hence, you not only get a safe and
reliable power supply, but maximum cost savings too!
è Global cost optimization
Integration &
System Topology
Hybrid Controller Integration:
We at BELECTRIC understand that most customers have existing energy infrastructure that they cannot
completely replace. The BELECTRIC Hybrid Controller is a highly versatile and flexible unit which helps to easily
integrate PV and battery into your existing energy infrastructure and ensures a reliable and cost-optimized
power supply at all times.

Hybrid Controller System Topology:
The overall control unit is the Grid Control Box (GCB) which determines the required set points for the different
units of the hybrid power plant and gives commands to the distributed Power Control Boxes (PCB). The PCBs
control the different generation units through individual Programmable Logic Controllers (PLC).
