Abstract

The current power grid is a hierarchical and partitioned power grid, and the power supply adequacy of the partitioned 220kV power grid needs to be evaluated in real time. The article analyzes the sensitivity between the branch power flow and the node load, the sensitivity between the branch power flow and the generator active power, and deduces the optimization model of the power supply adequacy of the district power grid. This paper uses a linear optimization method that takes into account the power flow section constraints and the branch power flow sensitivity to solve the model. This paper uses the IEEE30-node system as a calculation example to verify the above method. The results show that the real-time assessment of the power supply adequacy of the power grid can calculate the maximum power supply capacity of the regional power grid and reflect the current operating conditions of the power grid.
