In photovoltaic power generation systems, power conditioning systems (PCSs) and charge-discharge controllers are used to convert direct current output from solar panels into usable alternating current. The parameters that indicate the performance of a power generation system include actual amount of generated power and conversion efficiency.
This paper presents an overview of the existing PV energy conversion systems, addressing the system configuration of different PV plants, and the PV converter topologies that have found practical applications for grid-connected systems.
Perspectives in PVB research including DC distribution system and carbon trading integration are presented. Due to the target of carbon neutrality and the current energy crisis in the world, green, flexible and low-cost distributed photovoltaic power generation is a promising trend.
Photovoltaic energy has grown at an average annual rate of 60% in the last 5 years and has surpassed 1/3 of the cumulative wind energy installed capacity, and is quickly becoming an important part of the energy mix in some regions and power systems. This has been driven by a reduction of cost of PV modules.
With battery installation to cope with the intermittent and fluctuating PV generation, the distributed photovoltaic battery (PVB) system is a typical prototype for distributed energy systems, and its design optimization is paid more attention to.
Directly capturing light and heat can improve the power generation efficiency of PV and TE systems. The use of nanowires or nanorods helps increase the amount of captured light . In addition, the use of gratings also enhances the capture of light [120, 121].
