POWER DEMAND/SUPPLY ADJUSTMENT POWER PROCUREMENT PLAN SUPPORT DEVICE AND METHOD, AND POWER DEMAND/SUPPLY ADJUSTMENT POWER PROCUREMENT PLAN SUPPORT SYSTEM

摘要

The invention eliminates a power transmission bottleneck due to power transmission congestion and supports planning of procuring power demand/supply adjustment power in the market at lower cost. A power demand/supply adjustment power procurement plan support device supports a power demand/supply adjustment power procurement plan of a power system through a power transaction in the power market and is characterized by being provided with an added power transmission capacity analysis means and a target power transmittable capacity determination means. The added power transmission capacity analysis means obtains: actual power supply data including a power supply having supplied power to the power system and the actual value of a power supply amount; an actual power system stabilization data including a power supply performing power supply restriction for power system stabilization, an electric control amount or a customer facility performing a load restriction, and the actual value of a load control amount; and an actual power demand/supply adjustment power procurement data including a procurement amount of the power demand/supply adjustment power of a power supply participating in the power market and the actual value of the total procurement cost. The added power transmission capacity analysis means then performs added power transmission capacity analysis on a power transmittable capacity of each consignment route of the power system and the power supply amount of each power supply in the total procurement cost of the power demand/supply adjustment power to obtain an added power transmission capacity. The target power transmittable capacity determination means determines a target power transmittable capacity for minimizing the total procurement cost from a current power transmittable capacity and a power supply plan on the basis of the added power transmission capacity obtained from the added power transmission capacity analysis means.
