A recent study led by Jiawen Sun from the State Grid Xinjiang Economic and Technical Research Institute presents a significant advancement in the management of renewable energy sources. The research, published in the journal Energy Informatics, addresses the growing challenge of integrating wind and solar power into the energy grid, particularly as their usage continues to rise.
As the scale of wind and photovoltaic (PV) energy increases, so does the complexity of ensuring a reliable and economical energy supply. The study proposes a multi-energy co-generation system that combines wind power, PV, concentrated solar power (CSP), and traditional thermal power. This innovative approach aims to mitigate the issues arising from the unpredictability of renewable energy sources and load demands, which can lead to inefficiencies and increased operational costs.
A key component of the research is the development of a stochastic optimal dispatch model that takes into account the conversion of electricity into heat. This model is designed to minimize the overall operating costs of the combined energy system while ensuring reliability. “The photovoltaic and thermal power plants are used to provide the system’s backup capacity together,” Sun explains. This collaborative approach is crucial in reducing the impact of prediction errors associated with renewable energy generation.
To enhance the reliability of the energy system, the research introduces an opportunity constraint model. This model ensures that backup capacity meets reliability standards at a higher confidence level, allowing for a more stable energy supply. By implementing a sampling-based deterministic transformation method, the researchers were able to simplify the complex model, making it more practical for real-world applications.
The commercial implications of this research are significant. Energy companies and grid operators can leverage this model to optimize their operations, reduce costs, and improve the integration of renewable energy sources. As businesses and consumers increasingly demand cleaner energy solutions, the ability to efficiently manage a diverse energy portfolio becomes essential.
In conclusion, the findings from Jiawen Sun and his team at the State Grid Xinjiang Economic and Technical Research Institute provide valuable insights into the future of energy management. By addressing the challenges posed by renewable energy integration, this research opens up new opportunities for the energy sector, paving the way for a more sustainable and economically viable energy landscape. The study highlights the importance of innovative solutions in meeting the demands of a rapidly evolving energy market, as detailed in the journal Energy Informatics.
