As a result, thermal units prioritize dispatching ones with lower carbon emission factors, and the absence of energy storage systems may lead to thermal power units taking on all peaking tasks, and requiring more frequent adjustment of output to consume wind and solar in power generation.
In Fig. 8(c), the regulation capacity of the system is improved after the introduction of the energy storage system, and the output of thermal power units is significantly reduced compared with Scenario 1 Simultaneously, the output of wind and solar power generation has increased proportionally.
When the penetration rate of wind power increases to a certain extent, relying solely on thermal power to cope with the uncertainty of wind and solar output will lead to frequent starting and stopping of thermal power units, threatening the safety, stability, and economy of the power grid operation (Ye et al., 2023).
The annual wind and solar power generation data are used to estimate the kernel density estimation function of wind and solar power generation, taking into account seasonal and temporal variations, that enables the determination of the corresponding mathematical expectations of wind and solar power generation.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
