Solar Grid-Connected Photovoltaic Power Generation Technology

This volume outlines the global energy situation and current status of photovoltaic power generation both in and outside of China. From there, it goes on to discuss the basic principles and electrical characteristics of photovoltaic cells, evaluating various major MPPT tracking algorithms and isolated island protection technologies, and analyzing the implementation of digital phase-locked loops (DPLL). It goes on to explore a variety of circuit topologies and common principles of mode current suppression techniques for non-isolated single-phase photovoltaic grid-connected inverters, alongside examinations of partial shadow problems and their suppression methods. It also covers single-phase and three-phase control strategies for PV grid-connected inverters, and the DPWM technology used to improve the efficiency of inverters. Finally, it evaluates various low-voltage, ride-through control methods.
