A zero switch and sensorless reconfiguration approach for sustainable operation of roof‐top photovoltaic system during partial shading

Abstract Photovoltaic (PV) roof‐top systems in real‐time environments are highly susceptible to the commonly occurring scenario of partial shading that occurs due unavoidable conditions such as shadow buildings and trees. The occurrence creates a serious mismatch among modules PV arrays results severe unexpected power losses arrays. conventional hybrid configurations used for loss mitigation sometimes unreliable incapable generating higher during shading. Hence, this paper focuses on development simple effective technique reliable operation reduction is applicable arbitrary array sizes having no dynamic parts requires switches sensors implementation enhance performance system. reliability have been investigated under MATLAB simulation scenarios by comparing it with various investigation reveals output proposed an average conversion efficiency than 90% enhancement 19.07% other configurations.
