Device for generating optimal scheduling model about virtual power plant, and method of generating optimal management model using the same

摘要

An apparatus for generating an optimal operation plan model of a virtual power plant (VPP) includes a power price prediction part, an input part and an operation plan model generation part. The power price prediction part predicts power price per time slot on a power transaction target day. The input part is inputted with power generation amount according to the time slot on the power transaction target day of each power generator which is a distributed power included in the VPP, power demand reduction amount according to the time slot on the power transaction target day of each of power demand reduction resources which are distributed powers and loads included in the VPP, discharge power amount according to the time slot on the power transaction target day of each of energy storage devices which are distributed powers included in the VPP, compensation unit price as to power demand reduction of the power demand reduction resource, and charging power amount according to the time slot on the power transaction target day of each energy storage device. The operation plan model generation part generates an objective function by subtracting a value obtained by multiplying the compensation unit price inputted from the input part and the power demand reduction amount, and a value obtained by multiplying a power price and the charging power amount, from a value obtained by multiplying the power price per time slot on the power transaction target day predicted in the power price prediction part and the sum of the power generation amount and the power demand reduction amount and the discharge power amount inputted to the input part, and generates a function maximizing an output value of the generated objective function as an income maximization objective function of the virtual power plant.
