This study optimizes collaborative operation of an integrated wind-PV-thermal-storage system centered on a 660 MW coal unit. A molten salt thermal energy storage (TES) is operated based on real-time electricity price threshold (400 CNY/MWh). Simulations using Shandong Province data show improved flexibility and peak shaving, with TES generating arbitrage revenue. The multi-energy system enhances renewable energy consumption and supports low-carbon transition.

📄 Abstract（原文）
Based on the global transition towards clean energy, this study investigates the collaborative operation and comprehensive benefits of an Integrated Wind-PV-Thermal-Storage Energy System. The system architecture centers on a 660 MW ultra-supercritical coal-fired unit, complemented by wind farms, photovoltaic stations, and a molten salt thermal energy storage (TES) system. A refined system model is developed, and an operational optimization strategy for the TES is established, utilizing a real-time electricity price threshold of 400 CNY/MWh to guide its charging during low-price periods and discharging during high-price periods. Simulations for typical winter and summer days were conducted using ThermoFlex and real meteorological/electricity price data from Shandong Province, China. Results demonstrate that the integrated system significantly enhances operational flexibility and peak-shaving capability. The TES effectively mitigates renewable energy intermittency and enables energy time-shifting. Economic analysis reveals that the TES generates substantial arbitrage revenue, increasing the system's comprehensive benefit by 0.3526 million CNY and 0.1878 million CNY on the typical winter and summer days, respectively, compared to the system without storage. This research validates the proposed multi-energy complementary system as a viable and effective solution for improving renewable energy consumption, operational economics, and supporting the low-carbon transition of power systems.
