AI Technical Summary
Existing technologies make it difficult to accurately assess the time frame and sources of constraints for the risk of missing ancillary services in wind-solar-storage combined power generation systems, resulting in a gap between understanding and execution of risk assessment and on-site operation control, and making it difficult to quantify ancillary service capabilities.
By triggering sampling through changes in active power, time alignment of measured active power at the grid connection point is performed to identify ancillary service demand segments. Based on the state of charge of energy storage, available energy boundary parameters are calculated to construct the reachability domain boundary of ancillary services. The unreachability tendency coefficient and limit parameters are output by calibrating the model using monotonic constrained logistic regression.
It achieves accurate characterization of the ancillary service requirements of wind-solar-storage combined power generation systems, can identify the time intervals and sources of unreachability, output executable limit parameters, improve the stability and interpretability of assessment results, and adapt to actual operating scenarios with fluctuations in wind and solar power output and changes in energy storage status.
