One cycle control for hybrid power system

Abstract

Solar energy and wind energy are highly depended on the climate. So, the available power is discrete. Hence two different renewable energy sources could be combined to get a demanded load power. Hence the system is known as a hybrid power system. Instead of several independent converter, in hybrid system multiple input converter have simple circuit and low cost. But multiple input converters have many modes of operation. So the control circuit is complicated. This paper explains an OCC (one cycle control) method for MIC (Multiple Input Converter) which is simple compared to other control methods. The working of OCC is explained in detail. In one cycle control no current regulator is needed and the design in different mode is simple. Thus, control design is simple.
