Study on interconnection standards of photovoltaic power generation

Under the force of environment issue and energy issue, distributed generation has achieved prodigious progress recently. And it is deemed to be the future development of modern power system. How to interconnect the new energy power generation with power system safely and reliably is a major challenge in the development of Smart Grid. New energy power generation interconnection standards are the technology base, which will push the development of smart grid. In this paper the distributed generation interconnection standards of home and abroad are studied. And the inadequacy of existing standards and that the distributed generation interconnection standards should focus on power quality, protection and control. This paper can be provided as a reference to improve existing standards and establish interconnection standards.
