Optimal Scheduling Strategy for New Energy and High-Energy-Consuming Industrial Park Self-Owned Power Plants Based on Generation Rights-Carbon-Green Certificate Trading

• • High-energy-consuming industrial parks contribute 42% of China's industrial carbon emissions with an emission intensity of 1.2 t CO2 per 10,000 CNY, underscoring the urgent need for integrated carbon-market mechanisms to avoid punitive carbon costs under the dual-carbon strategy. • • The proposed generation rights-carbon quota-green certificate conversion mechanism dynamically matches renewable output with self-owned plant regulation, enabling short-term generation rights trading that mitigates forecast deviations inherent in medium-to-long-term contracts and enhances renewable consumption. • • Integration of a CSP plant with thermal energy storage (TES) and an electric heater (EH) allows surplus wind/PV power to be stored as heat and dispatched during deficits, reducing the need for independent battery storage and lowering total system investment and operational costs. • • Simulation of a Jiuquan high-energy-consuming park validates that the ladder-type carbon and green certificate hybrid market design reduces carbon emissions and improves economic performance, achieving dual environmental and economic optimization compared to independent trading schemes.
