Abstract
:1. Introduction
- A comprehensive evaluation index that reflects the shiftable capacity and regulation costs has been established. The priority order for controllable loads to participate in shift control is determined based on this index.
- Compensation is provided on a time-of-use basis, with adjustable penalties for abandoning wind or solar power. The compensation amount and price are adjusted according to the varying levels of obstruction at different times.
- Controllable load enterprise engages in negotiations individually, so as to determine differentiated compensation prices. The equal revenue principle is utilized when the new energy generation enterprise negotiates with each controllable enterprises to ensure fairness.
