A prosumer reliability-enhanced method coupling post-fault reconfiguration and P2P trading

Abstract

Emerging market-based mechanims provide an effective way to satisfy consumers' differentiated reliability preferences and improve system reliability level. However, these mechanisms also increase the difficulty in determining the optimal post-fault network topology. To address the issues, this paper develops a prosumer reliability-enhanced method coupling post-fault reconfiguration and peer-to-peer (P2P) trading. Specifically, a bi-level optimization model is proposed where comprehensive cost paid by distribution system operator (DSO) is minimized in the upper level and prosumers' post-fault payoffs are maximized through multi‑leaders multi-followers (MLMF) game in the lower level. Then, a hierarchical distributed algorithm is designed to protect prosumers privacy in post-fault reconfiguration and P2P trading simultaneously. Numerical results authenticate that the proposed reliability enhancement method increases total social welfare and achieves win-win situation between DSO and prosumers.
