Beketov national university of urban economy in Kharkiv popup.description1 The aim of the project is to develop the theoretical basics, models, and new techniques for enhancing the energy efficiency during the retrofit of the centralized district heating supply networks with implementation of renewable energy sources and waste heat from the industry, and to provide the recommendations concerning their step-by-step resource-saving transition to the low-temperature district heating systems. popup.description2  The fourth stage of the project focuses on developing the architecture and requirements for the control system of the individual heat point (IHP), addressing modern demands for energy efficiency and the integration of renewable energy sources (RES). As part of this stage, a dynamic model of thermal processes in heat exchange devices was developed, incorporating their design features and enabling real-time simulation of heat transfer processes. PID controllers and predictive control models were designed to ensure stable system control amid variations in key parameters, such as coolant temperature and flow rate. These solutions are particularly recommended for heat exchangers operating under unstable conditions. A dynamic model of a heat pump was also developed, enabling the estimation of its control parameters. This model includes a digital twin of the heat pump's operation for scenarios involving low-grade waste heat from industrial processes and district heating. The proposed two-stage system, which can utilize energy from RES, ensures the autonomy and flexibility of the system. The model is universally applicable for studying varying waste heat input temperatures and working fluids. Additionally, a PID control model for a butterfly-type damper, used in centralized heating and IHP systems, was proposed. Regulator parameters were optimized to reduce fluctuations and enhance operational stability. A simulation model for the optimal distribution and consumption of energy was created, facilitating the analysis of various configurations and functionalities of IHPs. This model allows the evaluation of the economic feasibility of technical solutions and the selection of optimal parameters based on cost minimization. Based on the conducted research, the architecture and requirements for the IHP management system were developed. The system aligns with the principles of 4th-generation heat supply, supports distributed generation from RES, and integrates microgrid functional Product Description popup.authors Arsenieva Olha P.
