The Utility Problem

As electric distribution utilities aim to diversify and expand their energy generation mix, they focus on the influx of alternate energy sources, such as roof-mounted photovoltaic (PV) generation systems. This growing penetration of distributed PV generation in the grids poses new challenges for electricity distribution utilities, including their operations and planning. Distribution grid operators now face reduced and even reversed power flows at times of high PV generation and low load. This has various impacts, for example, voltage rise in the network. On the other hand, this situation brings some opportunities like the provision of locally sourced carbon offsets or credits or the chance to identify the areas of the grids which might be operated in island operations during extreme cases. 

For these reasons, knowledge of the PV generation per circuit (feeder) or substation is valuable information. Historically, distribution utilities have yet to implement a systematic approach to this insight widely. However, the datasets are becoming more readily available with the advancement of sensors and IoT devices in the grid. Distribution utilities might develop such an analysis better to understand the PV generation situation in the service area.
