Decision-Gated Surrogate-Assisted Stochastic Optimization with Independent High-Fidelity Certification for Photovoltaic Hosting-Capacity PlanningNew

This paper addresses photovoltaic hosting-capacity planning in power distribution systems under uncertain irradiance and demand. Its decision-focused, surrogate-assisted stochastic multiobjective framework jointly optimizes penetration and total electrical loss subject to reliability constraints. A calibrated PV model coupled with a distribution-network simulator serves as the high-fidelity reference, with independent high-fidelity certification built into the proposed method.
