Development of the control system for gas-hydrate power generation systems

When CO
₂
hydrate of 273 K is heated by 283 K, the pressure difference of nearly 3 MPa can be obtained by expansion of dissociated gas. Moreover, the heat cycle of generation of CO
₂
gas-hydrate and gas dissociation can use low temperature exhaust heat and the outdoor air temperature in a cold district. When an actuator is operated using the pressure difference of this heat cycle, the power generation system with a low environmental impact can be obtained. However, there is no example of examination until now regarding the control method of the gas-hydrate power generation system. Therefore, the gas-hydrate power generation system is modeled. The optimal control system is examined taking notice of the electric-power quality of the model described in the top. The proposed system which consists of various loads is assumed, the details of the control method which the stable supply of electric power can realize were clarified.
