CIRCUTOR DISPENSER Series - Manual (Page 19)

The net metering concept is applied to customers that have their own self-powered genera-
tor (usually a solar power generator).
Customers with a self-powered generator can consume the energy that is self-generated in-
stantaneously. However, excess production of energy might not need to be consumed during
some times of day. This is when the surplus energy can be injected into the electrical network
of a micro-grid and the Dispenser will reward the user by adding energy units that can be con-
sumed later.
This surplus energy injected into the grid is subject to the operating mode of the micro-grid at
the time of injection. The unit can measure the injected energy and manage it:
Applying penalties to energy injected during bonus periods.
 Awarding a bonus to energy injected during restriction periods.
Example of net metering:
A subscriber installs solar panels at their home to generate their own electricity. At a certain time
of day, the amount of energy generated by these solar panels exceeds the current consump-
tion. In this case, the surplus energy of the panels would be injected into the electrical network
of the micro-grid. The Dispenser will apply a penalty or bonus to the injected energy, according
to the operating mode of the micro-grid.
Micro-grid operating in the normal mode (Price factor =1):
If 1 Wh is injected into the grid, the Dispenser will add 1 unit of credit to the subscriber.
Micro-grid operating in the bonus mode (Price factor <1):
If 1 Wh is injected into the grid, the Dispenser will add <1 unit of credit to the subscriber. If the
price factor is 0.8, 0.8 units will be added to the user and not 1, since the micro-grid is operating
in the bonus mode and needs no additional energy.
Micro-grid operating in the restriction mode (Price factor >1):
If 1 Wh is injected into the grid, the Dispenser will add >1 unit of credit to the subscriber. If the
price factor is 1.5, 1.5 units will be added to the user and not 1, since the micro-grid is operating
in the restriction mode and needs additional energy, applying a bonus for the subscriber for the
injected energy.
3�5�2�2�- ENERGY BLOCKS CONCEPT
In the energy block operating mode, the price of energy varies according to the consumption.
The user can define 3 energy blocks through DISPENSER-SOFT, selecting the following for
each block:
- The price of energy of each block ( Price factor).
- The consumption after which the system skips to a different block ( Energy).
