PRICE INFORMATION SYSTEM FOR POWER TRADING

The present invention relates to a price information system for an electricity transaction, and more specifically to a price information system for an electricity transaction, which provides electricity transaction price information for electricity generated according to self-generation such as solar power, and corrects the difference in unit price for each contract demand, so that a transaction can be carried out. The price information system for an electricity transaction includes: a control unit (10) in which an arithmetic expression to calculate a correction rate (R) for correcting a difference in unit price for each contract demand for an power transaction is installed; a monitoring unit (20) in which a plurality of sensors for checking and the amount of power and the amount of power generation stored in a storage such as an ESS are grouped or modularized; an information input/output unit (30) which guides optimization information by selecting a buyer and a seller who can generate the maximum profit in terms of cost during an electricity transaction; a calculation unit (40); a memory unit (50); and a line management unit (60) which analyzes the shortest distance of a power line based on the transmission capacity of the power line for power transmission to set an optimal transmission path. 본 발명은 전력 거래 가격정보시스템에 대한 것으로 태양광과 같은 자가발전에 따라 발생되는 전기에 대한 전력거래 가격정보를 제공하고, 계약전력별 단가 차이를 보정하여 거래할 수 있도록 하는 전력 거래 가격정보시스템이다.
