Overview of technical specifications for grid-connected photovoltaic systems

Numerous countries are trying to reach 100% renewable penetration. Variable renewable energy (VRE), for instance wind and PV, will be the main provider of the future grid. Cost reduction of accelerates the large scale VRE deployment around the world. The efforts to decrease the greenhouse gases are promising on the current remarkable growth of grid-connected photovoltaic (PV) capacity. This paper provides an overview of the presented techniques, standards and grid interface of the PV systems in distribution and transmission level. This paper compares the different review studies which has been published recently and provides an extensive survey on technical specifications of grid connected PV systems. Moreover, the adopted topologies of the converters, a thorough control strategies for grid connected inverters, as well as their applications in PV farms has been studied. This study will help researchers and industry users to establish their research based on connection requirements and compare between different existing technologies.
