Transmission loss minimization management system

An ESS installation system for transmission loss minimization wherein

• an energy storage system (ESS) for storing power is installed between a power plant and a substation or between a power plant or a substation and a consumer as an auxiliary means of power supply, and
• the ESS comprises:
• a database unit comprising one or more pieces of real-time accumulated information, among specifications, use, and management state of the ESS for at least one ESS;
• a state information collection unit configured to collect and update information related to a state of charge (SoC) of the ESS in real time;
• a usage state recognition unit comprising situational information checked during use of the ESS;
• and
• a central controller comprising a means configured to regulate charging and discharging of the ESS when a transmission power capacity of the power plant and the substation and a power demand of the consumer are equal to or greater than a standard value.

A transmission relay cost charging method through transmission loss minimization management, the transmission relay cost charging method comprising:

• recording a demand curve of power transmitted from a power plant or a substation to a consumer;
• a transmission assistance step of transmitting pre-stored power from at least one energy storage system (ESS) installed between the power plant and the substation or between the power plant or the substation and the consumer as an auxiliary means of power supply when a power demand exceeds a certain level;
• charging the ESS when the power demand is equal to or less than the certain level;
• estimating a loss minimization cost of the transmission power calculated by dividing a daily time period into certain sections and calculating a transmission minimization cost by Mathematical Equation 1 below;
• and receiving compensation by charging all or some of a value equivalent to the amount to a supplier.
