분산 에너지 네트워크 시스템의 효율적인 제어기법

Distributed generation produces electricity from various prime movers, for example, fuel cells, gas turbines, gas engines, etc. without the problems associated with transmitting electricity over long distances, and thereby aids the entire grid (residential zone, commercial zone, etc.) by reducing demand during peak times and minimizing congestion of energy on the power network, which is one of the causes of blackouts. In particular, by-product heat from generation sources such as gas turbines or fuel cells could be used efficiently for local process such as water heating or space-heating, allowing flexible trade-off between the requirements for heat and electric power. However, it is never easy to manage a combined heat and power system to maximize operational efficiency. Therefore, we discuss the results of research, which identifies appropriate control methods to ensure an efficient pattern operation with regard to various electrical and thermal load patterns in two study zones by simulation. In the result, when the residential and commercial areas were connected, we concluded that the system could reduce primary energy consumption compared with considering them individually　and to primary energy consumption in conventional system.
