A method for optimizing the capacity allocation of a photovoltaic-pumped hydro storage system in an abandoned coal mine.

ABSTRACT: The enormous potential of the photovoltaic (PV) sector has aided in the faster attainment of China's "dual-carbon" aim. However, due to a scarcity of land resources and intermittent fluctuations in solar energy, it has been difficult to build large-scale PV bases, and existing PV systems also suffer from unstable power generation and seasonal fluctuations and are unable to be directly connected to the grid for use. However, abandoned mines with huge surface collapse zones and a large underground mining area offer a potential possibility for constructing photovoltaic-pumped hydro storage (PV-PHS) systems and limiting PV variations. Based on the abandoned mine pumbed hydro storage (AMPHS) potential assessment model and the optimized discrete wavelet decomposition algorithm, this study propos
