The multi-stage cascade converter structure can be fascinating for high-performance solar photovoltaic (PV) systems due to its interchangeability, expansion, and MPPT (Maximum Power Point Tracking) exception. However, power discrepancies in cascaded uniform PV converter modules can cause unstable voltages and system operation. This article highlights the problem, examines the effects of reactive power compensation and optimization on the safety and performance characteristics of the system and proposes a synchronized distribution of active and reactive power in the network in order to reduce this instability. Furthermore, a wind turbine is connected in parallel to the photovoltaic system to increase the reliability of the system. This document presents the standards and specifications of grid-connected photovoltaic inverters and the different topologies of grid-connected photovoltaic inverters. And he also discussed monitoring maximum credit points.
