In order to improve energy saving and reduction of operational cost by introducing distributed energy supply systems, control performance assessment during operation is indispensable. Thus, this paper assesses control performance of a heat recovery process in a gas engine cogeneration system, which is a typical distributed energy supply system, through numerical analyses. First, the influence of the control performance of the jacket cooling water temperature for stable operation of the gas engine on efficient heat recovery is examined. Then, the influence of environmental condition including ambient temperature and supply water temperature, and load condition such as supply water flow rate on efficient heat recovery is also evaluated. These numerical analyses show that the control performance of the jacket cooling water temperature is very sensitive to efficient heat recovery, while environmental and load conditions hardly have an influence on it.
