Abstract

In this paper

on the basis of actually connection way to the system and operation condition of the station

the influence of connection way of certain photovoltaic power station on local power grid is analyzed. As for the actual problem

several kinds of solutions are proposed. Such issue as changing the way of connection system for photovoltaic station to solve voltage over limit and PV output restriction of the grid connection point

throughout theoretical analysis

power flow simulation calculation and economic validation are proposed

which have great significance in ensuring power supply quality

safe and efficient operation.
