Multi-Time-Scale Demand Response Dispatch Considering Wind Power Forecast Error
摘要
Abstract
Wind power forecast error increases difficulty in power system scheduling,affects wind power accommodation,increases wind power curtailment and decreases system operation economy.A multi-time-scale demand response dispatch model was proposed considering wind power forecast error and characteristics of different kinds of demand responses.Firstly,a day-ahead price-based demand response dispatch swategy was built by analyzing residential users' response to price.Then in the day,the price-based demand response was dispatched again according to price deviation based on wind power forecast error.Secondly,a real-time incentive-based demand response dispatch model was established by analyzing compensate strategies for industrial and commercial users.This model took the minimal operation cost of the grid as objective function to decrease influence of the wind power forecast error on system dispatch and wind power accommodation.Lastly,case study showed that the multi-time-scale optimal dispatch could increase wind power accommodations,decrease system operating costs,ensure autonomy of consumers and reduce impact of demand response on them.关键词
