Building dump energy

What is dump energy?

What you call dump energy is, in my understanding, electrical power generation in a regional area, e.g. a low voltage grid area, where the power cannot be used in these moment and where the grid is on its limits (Voltage, Frequency or degree of capacity for the grid components) to receive the power.

What is a dump load in a solar energy system?

When the wind, solar, or hybrid wind-solar energy system used as a stand-alone system, the dump load (to absorb excess power when the storage unit is fully charged ) is a significant problem, due to timing mismatch between power demand and generation.

How much energy is transferred to a dump load as spilled energy?

According to the studies of Lu and Ma et al. , , , more than 50%, 48.6% (as shown in Fig. 1) and 30% of the total energy output were transferred to a dump load as spilled energy, respectively. Other studies also presented similar results , , , .

When does a battery dump occur?

Dump occurs whenever there is an excess of renewable energy (i.e. E x / d (t)> 0) and the state of charge of the battery is at maximum (i.e. SOC (t) = SOC max). This is an undesirable condition as the energy is wasted. To avoid this, dump energy could be consumed by the use of dump load , e.g. three phase resistor as utilized in .

Can dump energy be exported to the grid?

To avoid this, dump energy could be consumed by the use of dump load , e.g. three phase resistor as utilized in . Demiroren and Yilmaz put forward the possibility of exporting the dump energy to the grid, though with its attendant challenges.

Does a reduction in dump increase emission?

Plot of optimization objectives against generations. It is observed from the figure that at most instances, a reduction in dump results in an increase in emission. This is expected because a reduction in dump signifies a reduction in the number of the renewable energy sources.
