Detection of Invisible Solar PV Installations in Power Distribution System: A Review

Climate change has squeezed people to have massive coordination in carbon neutrality. Clean energy must prevail over power demand to achieve our goal. The net zero carbon emission roadmap encourages the energy sector to produce energy from alternative energy resources. Solar Photovoltaic (PV) systems, a distributed energy resource, are a promising solution to produce power with less carbon emissions. However, the high adoption of solar PV systems can cause negative impacts on distribution networks. The network operators should realize the capacity of distributed energy resources in their systems to maintain power supply and perform active local energy management. This study aims to fill the gap in the detection of invisible solar PV installations. In this paper, proposed PV identification and PV capacity estimation techniques are investigated. The processes of study are determined and summarized. The coming steps of this research area will be discussed in possible ways.
