The Research on Modeling Method of Electricity Price Response Characteristics of Large Industrial Users in Spot Market

Based on the node hourly electricity price in the spot market, the price response characteristics of large industrial users are modeled and analyzed. Under the given node hourly electricity price, the load in each hour of next day is optimized with the goal of minimizing the response cost of large industrial users. The functional relationship of price response under the hourly price is obtained by curve fitting. Taking a typical large-scale industrial user as an example, the model of response characteristics of the large industrial users under hourly price is calculated and obtained with MATLAB, which verified the feasibility of this modeling method.
