Research on Modeling and Appliance of a New Price Mechanism Demand Response

To absorb new energy generation to a great extent and lighten the burden of the grid, power supply company will need to dispatch demand side resources to regulate power load and decline the peak valley difference. Based on existing time-of-use price strategy, a quasi-real-time pricing strategy is proposed in this paper. In accordance with prediction of load and new energy generation, the new model can get the peak valley difference smallest, and provide benefits for customers and the grid both, by which a day-ahead 24h price arrangement will be given. This model can adjust load transfer rate based on variety of fixed load and transferrable load. A typical load curve is tested by using a PSO algorithm and an ideal result is obtained.
