Hybrid Power SystemHybrid Power System Hybrid systems by definition contain a number of power generation devices such
as wind turbines, photovoltaic, micro-hydro and/or fossil fuel generators.
The use of renewable power generation systems reduces the use of expensive fuels, allows for the cleaner generation of electrical power and also improves the standard of living for many people in remote areas

Table.1 represents the comparison among the three energy storage system such as Lead –acid battery, superconducting magnetic storage and flywheel storage system. From the above table we see that the flywheel is a mechanical battery with life time more than 20 years. It is also superior to other two with regards to temperature range, environmental impact and relative size

SYSTEM SIZING AND SIMULATION
Smart Energy (SE25) flywheel from Beacon Power Corporation is used for the system sizing which has highly cyclic capability, smart grid attributes, 20-years design life and sustainable technology.
Simulation is done in HOMER . For Homer simulation we used two conditions.
1. Simulation Without Flywheel
2. Simulation With Flywheel Fig: Beacon SE25 Flywheel

Results clearly shows that an addition of a flywheel system will
Reduce excess electricity, Increase maximum renewable penetration, Reduce fuel consumption, and number of diesel starts per year, Increase operational life and reduce emissions.
From Ramea system simulation in Simulink , it clearly shows that a step change in the load of 50kW will lead to a frequency deviation of 0.3Hz. System flywheel will provide more that 50kW for few seconds to maintain system frequency.
Based on the Experimental observations, a control system is designed for minimum input energy and maximum output energy. Visual Basic language is used for the designed control system.
RESULTS AND CONCLUSION
Therefore, we suggest an addition of a 25kWh flywheel system to Ramea hybrid power system.
