Abstract

The invention relates to a day-ahead schedulable potential evaluation method and device for a regenerative electric heating virtual power plant, and the method comprises the following steps: 1, obtaining a demand response excitation time period and a subsidy price, obtaining user thermal load data according to historical data, obtaining regenerative electric heating equipment model parameters according to equipment parameters, constructing a single regenerative electric heating day-ahead optimal scheduling model, and determining single regenerative electric heating output; 2, constructing a schedulable potential evaluation model of the single regenerative electric heating system according to the single regenerative electric heating output determined in the step 1, and calculating the schedulable power of the single regenerative electric heating; and 3, constructing a day-ahead schedulable potential evaluation model of the regenerative electric heating virtual power plant according to the regenerative electric heating schedulable power calculated in the step 2. According to the method, the electricity price type excitation can be responded to on the premise of guaranteeing the comfort level of the user, and the demand response potential of the regenerative electric heating system is well represented.

Description

technical field [0001] The invention belongs to the technical field of power systems and automation thereof, and relates to power system demand response, in particular to a method and device for assessing the dispatchable potential of a heat storage type 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 spinning 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 behavior, alleviate the contrad...
