Obiettivo To install a 150 kW wind turbine on the small island of Agios Efstratios connected to the local grid of 270 kW in order to cover the maximum possible of the island's energy including the heating and hot water needs of a building. Innovation lies on the flywheel application for this size of machine and the very weak diesel grid.It is proposed to install a 150 kW wind turbine on the island of Agios Efstratios in order to cover part of the island's energy demand and the heating and hot water needs of a building. The island has a permanent population of 250 persons and the electricity is supplied by a small diesel plant of 270 kW (3 x 90 kW) installed capacity. The peak demand for 1987 was 180 kW and the low 15 kW. Therefore the cost of the produced energy is extremely high, reaching almost 1,2 ECU/kWh. Although the island has a very high wind potential (more than 8 m/s AMWS) no extensive use of wind energy is possible since the grid is small. A controller will keep constant the percentage of the power fed to the grid by the wind turbine with respect to the power demand. A flywheel system will be used in order to smoothen the power fluctuations of the wind turbine and thus to increase the penetration ratio of the wind to the grid.The heating of the building will be done by using a set of electric storage radiator (heater) units of 40 kW total installed capacity. Their ability to store energy for several hours during the day will help the functioning of the whole system. A hot water reservoir with electric resistance heaters ( and a small boiler for cases of emergency) will be used as dump load of the system.A load management system will be also used in order to balance the fluctuating electricity demand with the power output of the wind turbine by using a so called peak saving control strategy. The remaining energy surplus will be fully utilised as dump load either for the heating of the building or for the water heating. In this way the integration of wind energy can be optimized. For the realization of this project the manufacturer of the wind turbine will have to cooperate with RAL (design and measurements) and CRES (for the rest and measurements).
