Abstract

To address the operational instability of the geothermal reheated dual-pressure organic Rankine cycle （R-DPORC） system caused by transient fluctuations in cold/heat sources

this study proposes two targeted control strategies： constant-load control and variable-load control. A dynamic simulation model of the R-DPORC system has been developed using Matlab/Simscape to analyze its dynamic response characteristics under varying cold/heat source conditions and load changes. The variations in system efficiency

degree of superheat

pressure

and mass flow rate are investigated. Results indicate that regulating the flow rate of working fluid pump is a critical method for achieving dynamic control of the R-DPORC system. Depending on specific operational scenarios

different operating modes can be flexibly combined. Through adjustments

the system can gradually achieve a new stable state and meet output requirements. Moreover

the optimized control strategy significantly improves the dynamic adaptability of the system under complex operating conditions

ensuring long-term stable operation and higher energy efficiency.
