In the quest for a more sustainable energy future, researchers are increasingly turning to virtual power plants (VPPs) as a means to integrate renewable energy sources and enhance grid stability. A recent study published in *Power Engineering and Technology*, led by Zhaoze Li from the School of Automation and Electrical Engineering at Inner Mongolia University of Science and Technology, offers a novel approach to optimizing VPPs by incorporating generalized energy storage and advanced control strategies.
The study focuses on a hierarchical optimization and control scheme for VPPs, which includes both wind power and photovoltaics. The upper layer of the scheme is designed to track generation scheduling and introduce VPPs to consumers using master-slave game theory. This approach allows for the use of genetic algorithms to refine electricity pricing at different times of the day, thereby responding to user demands and reducing the net load peak and valley differences.
“The key innovation here is the integration of generalized energy storage with VPPs,” explains Li. “This allows us to better manage the intermittency of renewable energy sources and ensure a more stable and reliable power supply.”
The lower layer of the scheme involves external power trading as a guarantee, combined with generalized energy storage to balance power supply and demand. The study also employs the Sinh Cosh optimization algorithm to enhance source storage and ensure that the VPP operates under low-carbon conditions.
One of the most compelling aspects of this research is its potential to increase the level of renewable energy consumption and promote regional decarbonization. “By optimizing the operation of VPPs, we can significantly improve the comprehensive operational efficiency of these systems,” says Li. “This not only benefits the environment but also offers economic advantages for energy providers and consumers alike.”
The study compares different schemes and demonstrates that the proposed approach can effectively increase renewable energy consumption and promote regional decarbonization. This research could have significant implications for the energy sector, particularly in regions with high renewable energy potential but limited grid infrastructure.
As the world continues to grapple with the challenges of climate change and energy security, innovative solutions like those proposed by Li and his team will be crucial in shaping the future of the energy landscape. By leveraging advanced control strategies and generalized energy storage, VPPs can play a pivotal role in the transition to a more sustainable and resilient energy system.
