In the rapidly evolving landscape of energy, a groundbreaking study led by Yang Hu from the Electric Power Research Institute, China Southern Power Grid, is set to redefine how distributed energy systems operate within the future energy internet. The research, published in ‘Zhongguo dianli’ (China Electric Power), delves into the operational modes of distributed generation systems, proposing a novel approach that could revolutionize the energy sector.
Traditionally, distributed energy systems have relied on a “unified purchase and sale” model, where energy is bought and sold in a straightforward manner. However, Hu’s research introduces a more dynamic and efficient model: the “aggregation service provider” (ASP) mode. This mode leverages energy internet technology to create a more integrated and responsive system. “The ASP model not only optimizes energy distribution but also enhances the overall efficiency and reliability of the system,” Hu explains.
The ASP model introduces two main types of auxiliary services: frequency regulation and voltage support. These services are crucial for maintaining grid stability and ensuring a consistent power supply. The study provides detailed calculation methods for expected costs and benefits, offering a clear pathway for energy providers to adopt this new model.
To illustrate the practical implications, the researchers conducted a numerical analysis using an industrial park as a case study. The results were striking: the ASP model demonstrated significant cost savings and improved benefits compared to the traditional model. This finding underscores the potential for widespread adoption across various sectors, from industrial parks to residential areas.
The study also highlights the impact of key parameters such as grid prices, photovoltaic subsidy prices, auxiliary service prices, and output distribution coefficients on the static payback period. These insights are invaluable for energy providers looking to optimize their operations and maximize returns.
The implications of this research are far-reaching. As the energy sector continues to shift towards more decentralized and renewable sources, the ASP model could become a cornerstone for future energy systems. It offers a pathway to greater efficiency, reliability, and cost-effectiveness, all of which are critical for sustainable energy development.
For energy providers, the ASP model represents a significant opportunity to enhance their operational capabilities and stay competitive in a rapidly changing market. By adopting this model, they can better manage energy distribution, reduce costs, and provide more reliable service to their customers.
As the energy internet continues to evolve, Hu’s research provides a roadmap for the future. It challenges traditional models and offers a vision of a more integrated, efficient, and sustainable energy system. The findings published in ‘Zhongguo dianli’ (China Electric Power) are a testament to the innovative thinking and rigorous analysis that are driving the energy sector forward.
