In the rapidly evolving energy landscape, the integration of distributed new energy power generation devices has transformed the traditional one-way power flow in distribution networks into a dynamic, bidirectional system. This shift, coupled with the emergence of end users contributing power back to the grid, has necessitated a reevaluation of the existing grid structure. Enter YIN Zhan, a researcher from the State Grid Shanghai Jiading Electric Power Supply Company, who has been exploring innovative solutions to optimize this complex network.
YIN’s recent study, published in the *Journal of Science and Technology of Harbin University*, introduces a novel AC/DC hybrid distribution network structure that leverages power routers to facilitate medium voltage DC interconnection between different distribution areas. This approach creates a networked DC energy layer, enabling optimized power flow across the entire distribution network.
The research employs AC-DC hybrid power flow calculation tools to simulate the operation of this new distribution network structure. Building on this, YIN utilizes the particle swarm optimization (PSO) algorithm to fine-tune the network’s performance. The results are promising, demonstrating significant improvements in network loss and node voltage status.
“This new distribution network structure has a large optimization effect on the network loss and node voltage status of the distribution network,” YIN explains. The implications for the energy sector are substantial. By enhancing the efficiency and reliability of power distribution, this technology can support the integration of more renewable energy sources, reduce energy losses, and ultimately lower costs for consumers.
The commercial impacts of this research are far-reaching. For grid operators, the ability to optimize power flow in real-time can lead to more efficient grid management and reduced operational costs. For energy providers, it opens up new opportunities to integrate distributed energy resources and enhance grid stability. For consumers, it promises more reliable and affordable electricity.
As the energy sector continues to evolve, innovations like YIN’s AC/DC hybrid distribution network structure will play a crucial role in shaping the future of power distribution. By optimizing the flow of electricity, this technology can help meet the growing demand for clean, reliable, and affordable energy, driving the transition towards a more sustainable energy future.
YIN’s work, published in the *Journal of Science and Technology of Harbin University*, represents a significant step forward in the quest for a more efficient and resilient power grid. As the energy sector continues to evolve, such innovations will be crucial in meeting the challenges and opportunities of the future.
