Survey of the Current Status of Integrated PV System

Abstract

This paper briefly introduces the integrated condition of PV integrated systems. The principles and characteristics of two significant forms of PV-integrated systems (distributed PV-integrated systems and large-scale centralized PV-integrated systems) are described in detail. Analyzed are the following issues brought on by the two PV-integrated systems linked to the grid: issues with power quality (harmonics, frequency, voltage amplitude), the islanding effect problem, the problems of reliability and stability of the PV-integrated system, etc. Feasible countermeasures are put forward for the above problems. Inadequate and possible improvements to existing technology are mentioned in this paper. The major causes of each sort of issue brought on by PV-integrated power production systems connected to the electrical grid, the state of domestic and international research, and the solutions are all reviewed. The future trend of large-scale industrial application of PV power generation technology has been prospected.
