Abstract

Abstract: The conventional method to satisfy grid peak load requirement is increase peak regulation installed capacity. However, short sustention period of electricity peak load leads to very low economic efficiency with this method. The stochastic and intermittent characteristics of new energy source also bring new challenges to energy dispatch. A user stimulus-response behavior model is built to coordinate and optimize resources on both supply and demand sides. The model considers roles of supply-side and demand-side incentives on power grids containing new energy resources such as wind power. The composite control strategy on demand side can effectively complement and enrich the demand response theory in wind power optimization scheduling. The model is tested with regional wind power forecasting and summer typical daily load data. Testing results show that proposed model can flatten load curve and reduce grid operation cost effectively.

Key words: demand response, energy scheduling grid, wind power, new energy resource
