“…As the circuit being studied has a nonganged (single phase voltage control) load tap changer the only control action that should be detected on the circuit is the switched capacitor banks located at the substation. The control of these capacitor banks is described in [10]. Generally speaking, the capacitors are switched to support the VAr requirements of the local loads and to support the subtransmission voltage.…”

High penetrations of distribution connected photovoltaic (PV) systems are becoming more common. However, the impact of these variable generators on system voltage and automatic voltage regulation equipment is not well quantified. In contrast to load which generally has some diversity, PV systems are often non-diverse over small geographic areas. Variability caused by PV can range from relatively slow changes in system voltage to high frequency impacts on real and reactive power. These changes have the ability to impact the operation of a distribution circuit from a protection, voltage control and load prediction/modeling point of view.This paper utilizes information from high resolution data acquisition systems developed at the National Renewable Energy Laboratory and deployed on a high-penetration PV distribution system to analyze the variability of different electrical parameters. High resolution solar irradiance data is also available in the same area which is used to characterize the available resource and how it affects the electrical characteristics of the study circuit. This paper takes a data-driven look at the variability caused by load and compares those results against times when significant PV production is present. Comparisons between the variability in system load and the variability of distributed PV generation are made. Additionally, the potential impacts of high-penetration PV on voltage regulation equipment such as capacitor banks and load tap changing transformers are quantified.

“…Additional analysis indicates the potential for high capacity credit at low solar PV penetration when, as in many cases, there is a high degree of coincidence between solar PV production and demand (Perez et al, 2008). Network-connected PV systems use inverters for grid interfacing, enabling in principle control of electrical characteristics relevant for grid integration (McNutt et al, 2009). With additional controls it is possible for PV to even provide active power control through the plant inverters (Achilles et al, 2008), although this is always at a loss of PV production.…”

Large penetration of rooftop PVs has resulted in unacceptable voltage profile in many residential distribution feeders. Limiting real power injection from PVs to alleviate over voltage problem is not feasible due to loss of green power and hence corresponding revenue loss. Reactive capability of the PV inverter can be a solution to address over voltage and voltage dip problems to some extent. This paper proposes an algorithm to utilize reactive capability of PV inverters and investigate their effectiveness for voltage improvement based on R/X ratio of the feeder. The length and loading level of the feeder for a particular R/X ratio to have acceptable voltage profile is also investigated. This can be useful for suburban design and residential distribution planning. Furthermore, coordination among different PVs using residential smart meters via a substation based controller is also proposed.
