Model of Total Supply Capability for Distribution Network Based on Power Flow Calculation
摘要
Abstract
The models and methods of total supply capability (TSC) for power distribution network do not take network loss and voltage drop into account, so it is hard to be applied to the real power system. Firstly, this paper proposed the model of TSC based on the power flow calculation which formulated the network loss and voltage drop. This model was also based on the link of feeders;and considered not only the load of feeders, but also the N-1 contingency for transformers and feeders. Secondly, considering the nonlinearity and iteration of the model, this paper proposed a method which was based on the backward/forward sweep algorithm and general reduced gradient method. Finally, the result of this paper was compared to the old feeder-based model and it passed the N-1 simulation. The results show that the TSC is just on the boundary of N-1 security, which means that the proposed TSC model is accurate. The proposed model is a foundation for the TSC application from planning to operation.关键词
