Webbconvex barrier can be a severe limitation on the effectiveness of relaxed verifiers based upon it. While the convex relaxation barrier can be bypassed in various ways (e.g. considering relaxations for multiple neurons [34]), as noted in [32, Appendix A] all existing approaches that achieve this do so by trading off clarity and speed. Webb11 apr. 2024 · Storage-concerned Alternative Current Optimal Power Flow (ACOPF) with complementarity constraints is highly non-convex and intractable. In this letter, we first derive two types of relaxation conditions, which guarantee no simultaneous charging and discharging (SCD) in the relaxed multi-period ACOPF. Moreover, we prove that the … Webb27 mars 2024 · The convex relaxation and sensitivity methods are applied in lower-level and upper-level algorithms, respectively.
