Risk Assessment and Empirical Analysis of Grid connected Distributed Photovoltaic Power

Due to internal and external factors, after grid collected distributed photovoltaic power, it will bring risks for grid operation. By analyzing five aspects including policy risk, environmental risk, power quality risk, grid operation risk and grid efficiency risk, this paper proposed a risk evaluation index system after grid collected distributed photovoltaic power. Then an empirical research about that was carried out with AHP and the fuzzy mathematics method, with a hope of giving some reference to the construction and promotion of grid connected intermittent power such as photovoltaic power.
