A METHOD FOR THE IDENTIFICATION OF CONFIGURATIONS OF PV WIND HYBRID SYSTEMS FOR THE RELIABLE SUPPLY OF SMALL LOADS/

Autonomous systems on the basis of PV and wind generators in combinati on with a battery storage are an option for the supply of small electr ical loads at remote locations. The systems may be supplied by a wind generator or a PV generator alone, or by a combination of both. To dec ide on the system configuration that should be applied in a certain ca se it is necessary to identify all possible configurations that satisf y the desired level of reliability. From these configurations, an opti mal one may be extracted by the application of economic measures for e xample. For European sites we present a new approach to the determinat ion of the combinations of generator and storage sizes that will guara ntee a high level of system reliability. A set of equations has been i dentified that link the sizes of the system components (PV generator, wind generator, battery) directly with parameters that characterize th e meteorological conditions at the respective site. The meteorological parameters applied are all gained from data sets given in the Europea n Solar Radiation Atlas and the European Wind Atlas. Copyright (C) 199 7 Elsevier Science Ltd.
