An Evaluation Method for Power Supply Capability of Distribution System Based on Simplified Grid Structure

Abstract:

This paper proposes a method to evaluate power supply capability of distribution system considering the connection mode of high voltage network. Firstly, based on the operation mode and load transfer of distribution network, the grid structure is simplified by forming incidence matrices between main transformers and high voltage distribution lines. Then a nonlinear programming model of power supply capability is developed through N-1 contingency analysis of high voltage distribution lines and main transformers, and the power supply capability of a distribution system can be obtained by solving the relevant model. The correctness and effectiveness of the proposed method are verified by a case study.
