Title:
POWER GENERATION SYSTEM OF RENEWABLE ENERGY
Document Type and Number:
Japanese Patent JP2021083267
Kind Code:
A
Abstract:
To provide a power generation system of renewable energy for maximizing a profit.SOLUTION: A power generation system of renewable energy includes: a power generation apparatus of renewable energy, which is a power generation facility using the renewable energy; a power storage apparatus that stores an electric power; a load that consumes the electric power; and a power control device that controls the electric power. In the power generation system of the renewable energy, the power control device creates a predicted power demand which predicts an electric power to be consumed by the load, and a predicted power to be generated which predicts an amount of an electric power to be generated by the power generation apparatus of the renewable energy, on the day on which an electric power plan is carried out; sets the time when the electric power by the power generation apparatus of the renewable energy starts being stored in the power storage apparatus, and the amount of power to be stored, and stores the predicted power to be deficit which is a difference between the predicted power demand and the predicted power to be generated, in the power storage apparatus, in preparation for the case when the predicted power demand exceeds the predicted power to be generated; calculates a predicted power storage cost in the case where the power is discharged, and a predicted power receiving cost which is a cost to be paid when the predicted deficient power is supplied by a purchased power from the power system; and controls the power storage apparatus and the power to be purchased, on the basis of the predicted power storage cost and the predicted power receiving cost.SELECTED DRAWING: Figure 1
