N2 - Differential power processing (DPP) is a promising architecture to solve the issue caused by mismatches among PV submodules. With widely-researched of DPP architectures in the photovoltaic generation system (PGS), their reliability is being studied extensively. This paper presents a comparison of the reliability between PV-to-bus (PV-bus) and PV-to-isolated port bus (PV-IP) architecture. This work uses the Markov model to compare the long-term steady-state availability of PV-bus and PV-IP architectures. The mathematical model will be used to analyze the long-term availability of these two DPP architectures. The power distribution in these two architectures under different partial shading conditions (PSCs) will be considered as an important factor to affect the reliability of the system.
