Abstract
This chapter deals with the so-called sizing ratio (Rs) of grid-connected photovoltaic (GCPV) systems and the relationship of this parameter with the maximum available power at the output of the PV generator subsystem. Additionally, the optimum value of the aforementioned sizing ratio of a GCPV system is defined as the one that maximizes the yearly energy efficiency in the PV installation considered.
The chapter defines Rs of a GCPV system with static configuration, and, starting from the respective PV generator (PVG) and central inverter models, it proposes a systematic procedure to determine its optimum value. This procedure will be adapted later to address the determination of the sizing ratio in reconfigurable GCPV systems. In fact, the chapter shows systems with adjustable Rs, differentiating between systems that adjust the sizing ratio value by modifying the rated power of the energy-processing subsystem used at each moment (the so-called MIX or Multi-master systems), and systems that adjust the Rs value by modifying the nominal power of the PVG connected to each energy-processing system (so-called team-based systems).
Finally, the chapter addresses the issues related to the design of this type of systems, with their required control, and the increase of the maximum available power at the output of the PVG that can be achieved with the use of them versus the use of systems with static configuration or not reconfigurable.
