| Abstract |
The government is pursuing a greenhouse gas reduction policy in accordance with the agreement adopted at COP21 held in Paris in 2015. Therefore, public institutions are required to install new and renewable energy facilities, and the ratio of obligations is being gradually expanded every year. KEPCO operates a regenerative braking device support system that reduces power demand through demand management. Regenerative power is the surplus power generated when the elevator is operated. The total regenerative power capacity of the elevator that can be produced in Korea is 1GW, which is equivalent to one unit of Shinwol Sung nuclear power plant (1GW). In the case of existing 15-storey apartments, the electricity consumption of the elevator is about 4% of the total electricity consumption of the apartment and 25% of the public electricity. The monthly average monthly usage of one elevator is equal to or more than the average monthly usage of the first generation. The regenerative power increases in proportion to the amount of elevator usage. When an apartment is paid for installing a regenerative power module, it is difficult for the apartment to recover the cost of installing the regenerative power module quickly due to the power saving cost. Therefore, it is only economically effective to utilize the regenerative braking device support system implemented by KEPCO. In the case of a newly installed elevator, a regenerative power type elevator must be installed, Conventional elevators should contribute to minimizing the energy use of the building while minimizing the investment cost by installing regenerative power modules through the regenerative braking system support project. |
