The document discusses UK Power Networks' efforts to improve how they assess new PV connections to the electricity grid. It examines their research into monitoring local distribution networks, assumptions made in their assessment tools regarding factors like panel derating and diversity, and different tools used to evaluate voltage rise. It also analyzes records of existing distributed generation from G83 registers and Ofgem's FiT registers, finding many discrepancies. The conclusions recommend potential improvements to several design assumptions and suggest using Ofgem's more complete FiT generation data.
