Hybrid power plant without storage
PV-diesel-hybrid-power plants without storage have rather low capital requirements. In the picture there is an option to connect the plant to the grid, which is applied in regions with an unstable grid. In the typical off-grid solution, the electricity from the solar power plant is used with priority, the diesel gensets generate the missing gap between the solar output and the load from the island off-takers..
Hybrid power plant with storage
Hybrid power plants with storage contain an additional component in comparison to the plant-type described above. A battery storage is dimensioned in such a way that it can store energy until the diesel gensets start-up, if for example a cloud deteriorates the solar output. The costs of the additional battery components are quite substantial. So obviously, this plant type is associated with higher investment costs.
The advantages of adding a battery storage
The advantages of adding a battery storage cannot be neglected either. It allows on the one hand side for turning-off the generators during daytime and on the other hand side it can increase the renewable energy penetration considerably. The penetration rate indicates the percentage of renewable energy in the total power system. systems using diesel gensets, and despite their higher initial cost, PV systems can be amortized in as little as four to five years, depending on the site and system size, and they have low operating costs.
- Fuel save
- Store solar power when load less than solar power
- Peak shaving with sudden load ( No need for to start more DG)
- Minimal CO2 emissions (protects the environment and facilitates CO2 certificate trading)
