过电压是限制微电网输出并注入低压配电系统的有功功率的主要原因之一。考虑到低压馈线的阻抗主要是电阻性的，R/XL比很大，因此需要重新审视中压（MV）馈线中使用的众所周知的权衡。本文首先研究了具有均匀分布负荷和不可调度（有功）电源的径向低压配电馈线的有功功率和无功功率变化对电压和损耗的影响。分析中考虑了馈线特性和母线的净有功功率。这将给出关于如何在具有过额定逆变器的PV装置之间进行决定的指示，以获得无功功率控制的附加容量或能量存储装置，从而最大限度地减少峰值功率生产期间的过电压。
Overvoltages are one of the main reasons for limiting the amount of active power that can be exported by a microgrid and injected into a low voltage (LV) distribution system. The well-known trade offs used in medium voltage (MV) feeders need to be revisited considering the fact that the impedance of LV feeders is mostly resistive with large R/XL ratios. This digests investigates the impact of active power and reactive power variation on the voltage and losses of a radial LV distribution feeder with uniformly distributed loads and non-dispatchable (active power) sources. The feeder characteristics as well as the net active power of the buses are considered in the analysis. This shall give indications on how to decide between PV units with overrated inverters, for additional capacity of reactive power control, or energy storage devices, so as to minimize overvoltages during peak power production.
