Abstract

Abstract:

Integrated wind, solar, hydropower, and storage power plants can fully leverage the complementarities of multiple energy sources, with hybrid pumped storage serving as a key energy type in such systems. However, the mathematical model for hybrid pumped storage is highly nonlinear, which has not been integrated with wind, solar, and electrochemical storage in a unified configuration yet. To address this issue, a two-stage stochastic optimization model is established for the configuration and operation of an integrated power plant comprising wind power, photovoltaics, hybrid pumped storage, and electrochemical storage. Then, the big-M method and piecewise linear fitting are employed to relax the nonlinear parts of the model. Finally, the configuration and operational status of various energy sources as well as power generation schemes under different resource endowments are derived by simulation. The results indicate the competitiveness and economic viability of hybrid pumped storage in a complementary wind-solar-hydro-storage system.

Key words: wind-solar-hydro-storage integrated power station, comprehensive energy, configuration, multi-energy complementarity
