摘要
针对分布式光伏发电具有出力波动大、易受到天气变化影响的缺点,分析了光伏并网过程中的控制策略问题,研究了分布式光伏接入低压台区后对电能质量影响的机理因素,并通过实例仿真,得到了不同容量以及不同位置的分布式光伏电站接入低压台区后对用户电能质量的影响规律,为实际应用提供了理论基础。
The distributed photovoltaic generation has weaknesses.For example,it has large output fluctuations.Moreover,the weather changes highly impacted the distributed photovoltaic generation.This paper analyzed the control strategy of the photovoltaic grid-connected and studied the reasons and mechanism of influence of the power quality after the distributed photovoltaic and low-voltage transformer area connection.This research conducted the simulation example experiment and studied the influence of different capacity distributed photovoltaic power stations in various locations connected to the low-voltage transformer station.It obtains the influence law from the simulation example and provides a theoretical basis for practical applications.
