Generally PV power generation system consist of parallel connection of the PV strings which serially connected PVmodules. Partial shading has effect on efficiency of PV power generation system, causing mismatch between PV strings. Compensationmethods to reduce the mismatch loss have been investigated. these methods prefer to compensate the shaded PV modules increasesystem cost PV module weight. This paper suggests new method to reduce mismatch loss by compensating voltage to the string not toPV modules. Recognition of mismatch string is by comparing current between strings. only undervoltage is variably compensated toshaded string with low voltage source. imulation results with MATLAB/SIMULINK confirms the improvement of generationefficiency and compensation profit ratio.
