Abstract

The invention relates to a requirement responding scheduling method for wind power uncertainty. The method comprises a scheduling trading center predicts a benchmark load curve and a wind power generation curve and releases scheduling information to load agents; the load agents perform learning and decision making according to scheduling requirement information, system operation information and historical trading information and formulate bidding strategies and reports to strategies to the scheduling trading center; the scheduling trading center performs optimal scheduling on generation and consumption power resources with the lowest scheduling cost as the target after obtaining load agent bidding information and generator set calling cost information and sends scheduling instructions and final compensation price to the load agent and the generator set; the load agents adjust consumption power by means of electricity price adjusting and stimulation with the lowest scheduling cost as the target after obtaining final scheduling instructions. According to the method, an effective way is provided for wide-area distributed medium and small volume load resources to participate in system scheduling, the wind power volume load admitting capacity is improved, and the scheduling cost is reduced.

Description

technical field

[0001] The invention relates to a scheduling method in the field of AC and DC power system operation and control, in particular to a demand response scheduling method for wind power uncertainty. Background technique

[0002] Driven by factors such as energy resource shortage, climate change and environmental pollution, human beings have realized the importance and urgency of vigorously developing renewable energy. However, due to the "unfriendly" characteristics of wind power and other renewable energy sources such as volatility, intermittency, anti-peak regulation, and low dispatchability, it poses challenges to the traditional grid regulation method of "power generation tracking load". In order to cope with this challenge, the power supply, power grid and load should be coordinated and interacted, which is not only conducive to improving the energy and power dynamic balance capability of the power system, but also conducive to the optimal allocation of larg...
