Identifying the Optimal Point of Interconnection Based on the Complex Network Theory

Abstract:

The issue about choosing the point of interconnection is important to reduce the impact of Photovoltaic generation to the power grid security and investment. Here we present a model to identify the optimal point of Photovoltaic generation interconnection, based on the identification method of the critical elements in the complex network theory. In the model, the critical threshold is used as the measure index which reflects the minimum capacity of power grid to maintain every element stable operation. The simulations are carried out in the IEEE-118 power system, the IEEE-145 power system and the IEEE-162 power system, and the results show that the nodes with relative large electrical betweenness are good choice of the Photovoltaic generation interconnection points and the generation nodes are better choices compared to the transmission nodes. The work may have a certain guiding significance for the selection of Photovoltaic generation interconnection point and the planning of power system.
