| English Abstract: |
| In order to rationally use the reserve resources at the source side, a reserve risk assessment index based on stochastic power flow and semi-invariant method is proposed to accurately quantify the power flow over-limit risk caused by insufficient reserve. In order to realize the cooperative optimization of reserve resources at the source side and the controllable resources at the network side, the on-load tap changer and reactive power compensation device at the network side are included into the decision variables, and a source-grid coordination security and economic dispatching model of new power system considering reserve risk is constructed, which takes the minimum system operating cost and the minimum system operating over-limit risk index value as the optimal objects. Brownian motion and Levy flight random walk mechanism are integrated into the multi-objective differential evolution algorithm, and a novel Brownian-Levy multi-objective differential evolution algorithm is designed to efficiently solve the model. The effectiveness and superiority of the proposed method are verified by an example analysis. |
