Load Frequency Robust Control Considering Intermittent Characteristics of Demand-Side Resources

Renewable energy has the characteristics of low carbon and environmental protection compared to traditional water thermal power, but it also intermittency uncertainty that power does not have. These make inertia system increase, which greatly affects frequency stability grid. To solve such problems, participation demand-side resources (DSRs) in dispatch systems become a viable solution.However, unlike generation-side resources, DSRs have their own unique characteristics. In this paper, by taking into account load control (LFC) with intermittent robust H? problem are discussed detail.A controller coordinate side resource is introduced. A critical criterion performance evaluation new LFC was carried out. Finally, simulation results based on provided demonstrate proposed strategy can effectively improve robustness grid under large disturbances, thus allowing return reference value.
