Application of DC-DC Converters for Increasing of Power Production from Partially Shaded Photovoltaic String

Popis výsledku v původním jazyce

Nowadays, one common way to build the photovoltaic power plant is by connecting photovoltaic panels in series or parallel to form a string. The string is connected to main grid with an inverter. This conception is appropriate for a case when every panelis irradiated with homogeneous solar radiation. If some photovoltaic panels are shadowed or partially shadowed the string output power is dropped. The similar problem can occur if some photovoltaic panels are oriented in different directions in the casethe photovoltaic panels are radiated with different solar radiation. The result is similar to a partial shadowing. The problem can be solved by eliminating the non optional conditions. This is possible for application located in open area. The solution can be difficult to implement in urban areas. Photovoltaic panel may be overshadowed by a cloud cover, trees, chimneys, lightning conductors or other parts of buildings in urban areas. The different orientation cans occur if an installatio
