Modeling of a Controller for Fuel Cell Plants Connected to a Power Distribution Network

배전계통집 연겨계 연료전지 발전시스템의 제어기 모델링

This paper presents a methodology for effective control of fuel cell devices connected to the electric utility distribution network. A controller is designed for a fuel cell power plant to assist the conventional generators to damp out oscillations, which is possible by utilizing the fast response characteristic of fuel cells. Computer model of the controller is proposed and its effectiveness is proved by a sample test. Fuel cell devices can be used to improve power system stability when these are connected to a distribution system.
