Abstract:

In order to study the impact on distribution network caused by grid-connected photovoltaic (PV), the dynamic evaluation is used for evaluating the security of distribution. The index system of security assessment for distribution network with PV is established and OpenDSS software is used to simulate the volatility and randomness of PV power generation in the paper. The combination of superiority chart and entropy method is applied to gain comprehensive weights. Besides, the dynamic evaluation method is established based on fuzzy comprehensive assessment method and applied to the security evaluation of distribution network under different PV accessed capacity on the sunny day and cloudy day respectively. Also different power usage periods with different weights is assigned and second weighting is used to obtain the final evaluation results. The analysis examples indicate that the results by dynamic evaluation method are more close to the actual power usage.
