The developments of the solar and the wind power energy are necessary since the future alternative, energies that have no pollution and no limitation are restricted. Currently power generation system of MW scale has been developed, but it still has a flew faults with the weather condition. In order to solve these existing problem combined generation system of photovoltaic(400W) and wind power generation system(400W) was suggested. It combines wind power and solar energy to have the supporting effect from each other. However, since even combined generation system cannot always generate stable output with ever-changing weather condition, power storage apparatus that uses elastic energy of spiral spring to combined generation system was also added far the present study. In an experiment, when output of combined generation system gets lower than 12V(charging voltage), power was continuously supplied to load through the inverter by charging energy obtained from generating rotary energy of spiral spring operates in small scale generator.

A combined cycle, 'HYBRID', is emerging as a new power generation technology that is particularly suitable for the distributed power generation system, with high energy efficiency and low pollutant emission. Currently micro gas turbines and fuel cells are attracting a lot of attention to meet the future needs in the distributed power generation market. This hybrid system may have every advantages of both systems because a gas turbine is synergistically combined with a fuel cell into a unique combined cycle. The hybrid system is believed to become a leading runner in the distributed power generation market. This paper introduces a current plan associated with the development of the hybrid system which consists of a micro gas turbine and a solid-oxide fuel cell(SOFC).

Combined generation system of Photovoltaic and wind generation have shortcoming that is different output power according to change of weather. So, the combined generation system is required backup system that such as a storage battery to supply energy, when not enough photovoltaic and wind power source for power supply equally and continually because the energy source is changeable and stable through change of weather as irradiation. temperature, wind speed. wind direction. seasons, etc.

This paper describes the economic evaluation of battery energy storage system(BESS) for the domestic application. Application target is decided on conventional combined cycle of domestic and we analyzed economics that compared conventional combined cycle with power generation cost in development and the commercialized in case that establish it on utility and customer, urban and rural. The result shows that about the same conventional combined cycle of Anyang, Bundang and Pyungtak but more economical than seoincheon conventional combined cycle. And, in case of capacity enlargment and using the maintenance free battery more economical than conventional system.

The development of the solar and the wind power energy is necessary since the future alternative energies should have no pollution and no limitation. currently power generation system of MW scale has been developed, but it still has a few faults that its operation depends on with the weather condition. In order to solve these existing problems. combined generation system of photovoltaic(400W) and wind power generation system(400W) was suggested. It combines wind power and solar energy to have the supporting effect from each other. However. since the combined generation system cannot always generate stable output with ever-changing weather condition, power compensation device that uses elastic energy of spiral spring was added. In an experiment. when output of system gets lower than 12V(charging voltage), additional power was from the stored rotational energy of spiral spring.
