Dear Trnsys Users, I am Sharath Nellutla, working on a ICE system where I want to provide a power required to the load using Renewable energy sources, IC engine and Battery. Previously I changed the Fortran program of the Battery (Type 185) and I included a logic so that the max voltage at which the battery can be operated is 29.9 V. The Battery is charged using IC engine. And as per the logic I am allowing the IC engine to operate at P_setpoint = P_load + P_Charge for battery - P_Renewable. Where P_Charge of the battery= 75*Vbat But due to change in Battery Program when the voltage of the battery reaches to 29.9 V the power with drawn by the electrolyser is less and PINPUT-POUTPUT>>0. I am also attaching the plots of the system which shows how the charging of the battery varies when IC engine on and the difference beween Power Out and Power In. Is there any method I can control the SETPOINT for the IC engine so that its set point drops similar to power of the battery charging battery voltage reaches to certain point. I am also attaching the TYPE 185 Fortran program. Thanks, Sharath Nellutla 312 mail stop , Mechanical Engineering Department, University Of Nevada,Reno
