A Pricing Strategy for Key Customers: A Method Considering Disaster Outage Compensation and System Stability Penalty

Sustainability, Journal Year: 2025, Volume and Issue: 17(10), P. 4506 - 4506

Published: May 15, 2025

When power system equipment fails due to disasters, resulting in the isolation of parts network, loads within isolated cannot be guaranteed a continuous supply. However, for critical loads—such as hospitals or data centers—continuous supply is utmost importance. While distributed energy resources (DERs) network can some loads, outages may lead compensation and fairness issues regarding unsupplied loads. In response, this study proposes methodology determine appropriate contract price key customers by estimating demand networks incorporating both outage costs voltage stability penalties. The microgrid under consideration comprises DERs—including electric vehicles (EVs), fuel cell (FCEVs), photovoltaic (PV) plants, wind turbine (WT) plants—as well controllable such battery storage systems (BESS) hydrogen (HESS). It serves residential load clusters associated with social infrastructure. proposed structured two stages. normal operating conditions, optimal scheduling simulated using second-order conic programming (SOCP). event fault, mixed-integer SOCP (MISOCP) employed shedding strategy. A case conducted IEEE 123 bus test node simulate cost calculation penalty assessment processes. Based on analysis, that considers disaster-induced impacts presented.
