Hybrid Mini Power Plants (HMPP) is distributed generation power plants that
combines different energy sources.These sources can be either renewable or fossil energy sources (e.g. gas engines). The use of more than one energy source allows a higher stability of the
power supply. Moreover, the complementary profile of solar irradiance and wind
speed has brought to an increasing interest in wind-solar power generation
systems. The use of a fossil energy source combined with an energy storage
device (e.g. batteries) allows providing more power network services including
the stand-alone operation mode and UPS
services
· A combination of different but
complementary energy generation technologies based on renewable energies or mixed (RES + genset). Hybrid powered mini-grids can
provide steady community-level electricity service, such as village
electrification, offering also the possibility to be up graded to either more
capable systems or through grid connection in the future
·
Total installed power up to 100 kW
(according to IEC)

·
Distribution line in Low Voltage (up
to 1.000V) (only distribution) .Single or 3-phase grid.
Configurations
Hybrid Mini Power Plants (HMPP) can present two electrical configurations:
1. Connection of power sources on the AC side
2. Connection of power sources on the DC side
Conversion and Control Systems
The presence of an innovative Conversion and Control Systems allows to:
• Have the maximum exploiting of renewable source.
• Reduce the start stop of ICE generator (if it is present)
• Improve the ICE generator efficiency avoiding low power generation
conditions
• Use the energy storage system to adapt the load and generation power.
The presence of static switching on grid side
allows a fast transition from grid connected to stand-alone operation mode if a black- out event occurs. In this way the power
feeding of sensitive loads is guaranteed and the Hybrid power plants acting as
an UPS
