摘要

With the aggravating of environmental damage and energy shortage, it becomes a trend that distributed photovoltaic generation centrally accessed to distribution grid. Due to its vulnerability to weather, and the original power supply mode with a single power source is altered to the one with duplicate supply, which will change the power flow, the distributed photovoltaic generation increases the randomness of operational state, thus changes the operational risk of distribution grid. First, influence factors which caused by centrally accessed distributed photovoltaic generation are introduced. Then aiming at the characteristic that distributed photovoltaic generation is accessed in a single-point way, a method which uses probabilistic power flow algorithm based on sensitivity ideology is proposed to evaluate the operational risk. Finally, a case study is conducted to demonstrate the evaluation method proposed can provide standards for planning centralized access of distributed photovoltaic generation.
