Abstract

The invention relates to a method and device for assessing the dispatchable potential of a regenerative electric heating virtual power plant, comprising the following steps: Step 1, obtaining demand response incentive period and subsidy price, obtaining user heat load data according to historical data, and obtaining user heat load data according to equipment parameters Based on the model parameters of regenerative electric heating equipment, build a day-ahead optimization scheduling model for individual regenerative electric heating, and determine the output of individual regenerative electric heating; step 2. According to the output of individual regenerative electric heating determined in step 1, construct The evaluation model of the dispatchable potential of the individual thermal storage electric heating system, and calculate the dispatchable power of the single thermal storage electric heating system; step 3, according to the dispatchable power of the thermal storage electric heating calculated in step 2, construct the thermal storage electric heating system A day-ahead dispatchable potential assessment model for electric heating virtual power plants. The invention can respond to electricity price incentives under the premise of guaranteeing user comfort, and better characterizes the demand response potential of the heat storage electric heating system.

Description

technical field [0001] The invention belongs to the technical field of electric power systems and automation thereof, and relates to the demand response of electric power systems, in particular to a method and device for evaluating the day-to-day dispatch potential of a regenerative electric heating virtual power plant. Background technique [0002] In recent years, the large-scale application of intermittent renewable energy power generation has greatly affected the balance between power generation and power load in the power system, bringing unprecedented uncertainty to the safe and efficient operation of the power system. The fluctuation of power output on the source side needs to be balanced by the configuration of large-capacity rotating standby units, which brings high costs to the construction and operation of power companies. The load demand side response can achieve a certain degree of peak shaving and valley filling by changing the user's electricity consumption be...
