Abstract: Copyright © 2022 The Author(s). Research on preventive generation dispatch schemes for resilient power system operation is often based on the DC power flow model, ignoring the influence of reactive power and voltage magnitude. This paper presents an in-depth study of a linearized AC power flow (LAC) model with reactive power and voltage magnitude to derive sensitivity factors, including shift factors and line outage distribution factors, for pre-contingency and post-contingency power flow calculations for N-k contingencies. Based on the derived sensitivity factors, a resilience-constrained economic dispatch (LAC-RCED) strategy is developed, which considers the security constraints of N-1 contingency for all lines and N-2 contingency for the affected lines, as well as optimization objectives to improve the power flow distribution in the transmission system. To deal with the computational difficulties associated with the N-k contingency constraints, an iterative contingency filtering algorithm based on the derived line outage distribution factor is proposed for contingency screening and creating security constraints for violated contingency scenarios. In the case study, the accuracy of the power flow solution obtained from the derived sensitivity factors is investigated by comparison with the AC model. The proposed LAC-RCED model and the iterative contingency filtering algorithm are tested on the IEEE 30-bus and 118-bus systems.
Description: Data Access Statement: This study is a re-analysis of existing data from MATPOWER (https://matpower.org) and modified datasets from MATPOWER are provided in the Appendix of this paper. Appendix: The data of the modified 30-bus system includes the data of bus, branch and generator is shown in Table A.1, Table A.2, Table A.3, respectively. The data of the modified 118-bus system includes the data of bus, branch and generator is shown in Table A.4, Table A.5, Table A.6, respectively.
