UBLMN7-30-3 - Genset & Battery

Possible Benefits of Battery Hybrid Systems

- Reduce low-load running time
- Save fuel and improve life of generator
- Peak load with short duration
- Mainly depends on operation of batteries, low level of noise

Issues Discovered / Weakness with Battery Hybrid Systems

- Charging / Discharging of batteries will reduce life time of system
- Not suitable for system with very high peak load
- The load pattern cannot be complicated or very short life time system

Applications

Batteries application with other renewable energy is common.

Pros
- Source of renewable energy is not predictable. Excess energy can be generated (eg: PV panel, wind turbine), Batteries can help to store and to avoid waste of excess energy.
- Batteries allow temporary support to a rise in demand of energy. Therefore, they can help to prevent extension of public grid in responded to temporary demand, so reduce the investment cost.
- Flexibility of power supply can be consider to reduce cost because in some county the energy cost thought 24 hours per day is difficult. Batteries allow store at the time with cheaper energy cost.

Cons
- Batteries need repair maintenance, it increase maintenance cost.
- Control of batteries can be complicate and the interface is hard to follow
- Installation of batteries is an additional cost in a project.
