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
