A Method for Improving the Data Availability of Distributed Photovoltaic Power Plants

Abstract The growth of distributed photovoltaics is very fast, and there have been situations such as short-term low-voltage sending power to high voltage levels, a exceeding limits, inadequate operation maintenance. If data analysis not done well, it will affect the grid income station. This article analyses reasons for limited quality existing photovoltaic monitoring platforms. It proposes method that can improve availability plants. By reviewing repairing abnormal data, efficient application be achieved. identify 6 types from 25, 535 complete correction data. After correction, by comparing nearby stations, seen root mean square deviation 8.25%.
