DESCRIPTION:Integrated energy-system models become difficult to reuse when 
 electrical signals\, thermal-fluid states\, supervisory logic\, and evalua
 tion variables are coupled through inconsistent interfaces. This paper pre
 sents an OpenModelica platform with unit-explicit cross-domain connectors\
 , graphically encapsulated component models\, and a reusable library for r
 enewable generation\, conversion\, and storage. The thermal loop employs M
 odelica.Fluid ports and a temperature-dependent SolarSalt medium\, while t
 he wind and photovoltaic components expose available\, delivered\, and cur
 tailed power to support source-level curtailment feedback from the energy-
 management system. A DASSL-based workflow is applied to a full-year Dunhua
 ng case and complementary parameter-variation cases. The annual simulation
  maintains complete park electric-load supply\, achieves a heat-load satis
 faction rate of 90.16%\, and yields an electric LCOE of 0.307 CNY/kWh. Sta
 tevariable and sensitivity analyses indicate that renewablesource and batt
 ery sizing govern electrical absorption and economics\, whereas winter the
 rmal-storage availability and heat-side capacity constrain thermal reliabi
 lity. The platform therefore links reusable Modelica implementation with l
 ong-horizon system evaluation without requiring topology-specific reformul
 ation.
