| Abstract |
With the world`s highest density of transmission network, it is becoming increasingly difficult for Korea to build additional transmission network. Under these circumstances, decentralized power activation is a must, not an option. However, it sees the overload problem in the metropolitan area as insufficient to solve it through a traditional, distributed power source. Cogeneration is expected to serve as an alternative to eliminating transmission network congestion, as it is not only located in power demand but also contributes to power supply and can be operated immediately upon power peak, and is highly valuable as a distributed power source. However, due to differences in definitions of avoidance of transmission network according to views, the contribution of the cogeneration system is not clearly recognized for its contribution. In this paper, the benefits of using the power grid for the combined heat and power generation in the Metropolitan area were quantitatively calculated in terms of capacity[KRW/kW] and energy generation[KRW/kWh] by considering the operating conditions of the various power systems. The results were obtained by applying them to the Korea Power Corporation's 2018 power system and analyzed using the PowerWorld Simulator. As a result, we were able to learn that the cogeneration system in the metropolitan area has greatly contributed to avoiding the use of the transmission network in terms of power generation capacity and energy generation. |
