摘要

Currently, the scheduling model using DC power flow, thus it result in indirect considering of the voltage stability with checking. At the same time, there is lack of scheduling strategy for power system with multiple energy storage. A multiple time-scales scheduling strategy for power system with multiple energy storage which can directly considering voltage stability is proposed in this paper. Specifically, firstly, a linear AC power flow model that can directly reflect the voltage magnitude is presented; secondly, in order to consume new energy (NE), a multiple time-scales scheduling model combined with the linearized voltage stability constraint is constructed. Finally, the simulation results with the improved IEEE30 bus by GUROBI, show that the methods could meet the voltage stability requirements and effectively reduce the renewable energy abandonment rate.
