Abstract

The increasing integration of renewable energy sources and the rising frequency of extreme weather events have exacerbated supply-demand imbalances and heightened power outage risks. To mitigate these risks for residential users, this paper proposes a P2P outage insurance mechanism. A chain reinsurance framework is established, involving system operators, insurance intermediaries, and residential users, based on a pool-type P2P insurance model, along with its associated business processes. Premiums are determined using the standard deviation principle, while outage losses in complex networks are calculated through a reliability assessment method based on two-way traversal search. Furthermore, a premium sharing mechanism within mutual aid groups is developed using the Shapley value, accounting for the heterogeneous outage risks and losses of different users. The feasibility and effectiveness of the proposed mechanism are validated using an IEEE-RBTS numerical example. Results demonstrate that the mechanism enables effective risk sharing and fair cost allocation, indirectly enhancing system reliability, while reducing premiums by 22 % compared to traditional insurance. Accurate reliability assessment can be realized for distribution networks with backup power and sub-feeders.

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
