Novel Partial Shading Tolerant Short-Circuit-Current Based PV Maximum Power Point Tracking Technique

摘要

Commercial string photovoltaic systems exhibit performance degradation due to partial shading and/or irradiance mismatch as a result of missing global maximum power point. Several artificial intelligence based maximum power point tracking (MPPT) techniques tackle this problem and commonly suffer performance versus computational burden trade-off. In this paper, an efficient partial-shadingtolerant MPPT technique is proposed offering simple implementation, dead-beat like performance, minimal oscillation and reduce computational burden.
