On May 2, 2025, the National Intellectual Property Administration announced that Yunnan Electric Power Company Limited has applied for a patent titled “Method and System for Collective Control and Scheduling of Renewable Energy Stations and Energy Storage Power Stations”. The patent, with the publication number CN119891395A, was filed on December 2024.
The patent summary indicates that this invention pertains to the field of collaborative optimization technologies for new power systems, specifically addressing a method and system for the collective control and scheduling of renewable energy stations and energy storage power stations. This includes developing adjustable capacity models for both renewable energy stations and energy storage systems, as well as calculating their adjustable capacities.
Furthermore, the process involves computing power deficits based on the generation plan curve of the renewable energy collection station compared to its actual output. It then adjusts the generation output of both renewable energy stations and energy storage systems through an output distribution model. To ensure the state of charge (SOC) of the energy storage is properly maintained, an emergency maintenance strategy for SOC is also established. This unified control of renewable energy stations and energy storage subsystems enhances storage utilization, maximizes renewable energy absorption, and effectively alleviates the challenges associated with power tracking due to generation fluctuations.
According to data from Tianyancha, Yunnan Electric Power Company Limited was established in 1991 and is based in Kunming. The company primarily engages in the production and supply of electricity and heat, with a registered capital of 2,906,811,000 RMB. An analysis of their data reveals that they have invested in 151 enterprises, participated in 5,000 bidding projects, and hold 1 trademark and 3,481 patents. Additionally, the company has obtained 82 administrative licenses.
