Abstract

When supplying natural gas, KOGAS intends to utilize the new energy by installing a system that runs the generator using the energy generated when the high-pressure natural gas is reduced to low pressure, that is, TEG. In the past, the energy generated by decompressing natural gas in the supply management station was thrown into the air, but by using this to generate electricity, high-quality new energy that does not emit greenhouse gases and consumes fuel is obtained. This paper examines the characteristics of TEG power generation, examines the TEG pilot project and demonstration project conducted by Korea Gas Corporation, and discusses the voltage control scheme and grid interconnection.
