In the dynamic world of energy, the integration of diverse power sources is becoming increasingly complex. A groundbreaking study led by Wenhao Chao from the Engineering Research Center of Renewable Energy Power Generation and Grid-Connected Control at Xinjiang University, Urumqi, China, sheds light on a novel approach to optimizing power systems that include wind, thermal, nuclear, and carbon capture units, along with power-to-gas (P2G) technology. The research, published in ‘Zhongguo dianli’ (China Electric Power), addresses critical issues in peak regulation and wind power curtailment, offering a promising path forward for the energy sector.
The study introduces a linearized peaking depth model for nuclear units, which enhances their cooperation with P2G, wind power generation (WPG), thermal units, and carbon capture systems. “By adding continuous variables based on the load tracking mode of nuclear power units, we can significantly improve the accuracy of peak shaving depth selection,” Chao explains. This innovation is a game-changer for power systems, as it ensures that nuclear units operate safely and stably while maximizing the utilization of wind power.
One of the standout findings is the integration of a carbon capture power plant with P2G and demand response resources. This joint operation mode not only facilitates the accommodation of WPG but also contributes to a more sustainable energy landscape. The research demonstrates that this approach can reduce carbon emissions by 13.74% and comprehensive operating costs by 6.27%. “The minimization of system comprehensive operation costs, coupled with the carbon trading mechanism, builds a robust simulation model that verifies the effectiveness of our proposed model,” Chao elaborates.
The implications of this research are far-reaching. For energy providers, the ability to optimize the dispatch of power systems with multiple sources can lead to significant cost savings and environmental benefits. The integration of P2G technology and carbon capture units opens new avenues for renewable energy storage and utilization, making the energy grid more resilient and efficient. As the energy sector continues to evolve, this research provides a blueprint for future developments in optimal dispatch strategies, paving the way for a more sustainable and economically viable energy future.
