1. A virtual power plant system using a heat conversion device, comprising:
a plurality of distributed energy resources connected to a virtual power plant;
a virtual power plant output adjustment device connected to the virtual power plant and including a heat conversion device that receives power generated from the plurality of distributed energy resources and converts the power into thermal energy; and
a virtual power plant management device configured to conduct a bidding by predicting an expected power generation amount of the plurality of distributed energy resources, analyze output of the virtual power plant due to output of the plurality of distributed energy resources, and stabilize the output of the virtual power plant by controlling a power consumption amount of the virtual power plant output adjustment device based on the analysis result,
wherein the virtual power plant management device determines an individual bidding power generation amount of an individual distributed energy resource by predicting an amount of power generated by each distributed energy resource during a bidding period, and adjusts power consumption of the heat conversion device by comparing the individual bidding power generation amount and an actual power generation amount of the individual distributed energy resource, and
wherein the virtual power plant management device divides the bidding period into a plurality of sections, derives a section average value of the actual power generation amount of individual distributed energy resources for each section, and controls power consumption of the heat conversion device by comparing the section average value of each section for each section with the variable power source.
